Vacuum Die Casting Process
The polyurethane vacuum die casing process has three major steps:

Building the Master Pattern.

The master pattern can be made using an subtractive manufacturing process, CNC machining or additive manufacturing process like stereolithography (SLA) or Selective Laser Sintering (SLS) 3D printing processes.

Creating the Mold.

Putting master pattern into a casting frame and filling the frame with silicone material to shape a mold. Once cured, the mold is cut into halves and the master pattern is removed, forming a cavity to cast parts. One master pattern can be repeatedly used to leave multiple molds, making the vacuum die casting process an optimal option for on-demand, mid-to-low production runs.

Casting Products.

Injecting the liquid polyurethane material into the silicone mould and then placing the silicone mold in a vacuum chamber. When the mold hardens, the mold halves are set apart and the polyurethanes can be casted in vacuum pressure. 15-25 copies can be casted throughout the casting process in a repeated way.

Vacuum Casting Tolerances
The finished dimensions of vacuum casting parts depend on the accuracy of the master piece, part structure and casting material. As a general role, ± 0.25% tolerance is expected.

Vacuum Casting Material
LC Rapid has hundreds of materials to meet your unique production needs. These casting polymers can meet industry-specific applications requirements. There is also a wide range of colors available range from opaque, translucent, completely transparent or colored to match specific color requirements.

1. The importance of plastic CNC service

With the acceleration of product iteration in various industries, how to shorten the product development cycle has become the key to quickly occupy the market. From model design, prototype verification, small batch production or trial production to final batch production, this is a strict and orderly process. Plastic CNC service provides great convenience for obtaining plastic prototypes. With only 3D drawings, many mechanical products can be obtained within 1-2 days. In CNC processing, plastic is the most commonly used material. For plastics, the commonly used board/block materials are ABS, PC, PMMA, PP, POM, PBT, etc. The material properties are close to the production level of formal injection molding.

2. Plastic CNC processing services in car lights

(1) Plastic raw materials commonly used in plastic CNC services and processing precautions

A. Commonly used plastic raw materials

The use of plastic covers all walks of life. Compared with metal, stone and wood, plastic products have the advantages of low cost and strong plasticity. For many years, the production of plastic products has been developing rapidly in the world. Therefore, a large part of product development and design is related to plastics. For CNC prototypes, plastic CNC services also have a very wide range of needs. From the analysis of customer needs, it can be said that CNC plastics account for half of the usage. Usually, depending on the design size, the material used for CNC plastics will be plate or block material.

Currently, the most widely used CNC plastics are ABS, PC (polycarbonate) and PMMA (acrylic). Among them, ABS is an opaque material, while PC and acrylic resin have both opaque and transparent materials. For example, the design of car lights usually uses transparent acrylic as a material, which is polished to make it have a perfect transparent effect, and it is also used to verify the needs of optical and aesthetic design. Even the prototype of the famous FAW-Volkswagen brand's car lights also adopts plastic CNC services.

B. Processing considerations

Unlike metal, CNC plastic processing needs to slow down the processing speed, raise the cutter more frequently and have better cooling control to prevent the material from melting due to high temperatures during processing. Poor control not only makes it easy to process poor-quality products, but also severely damages CNC tools. In addition, the processing of plastic products is related to its material characteristics, and internal materials will generate stress. As a result, deformation and cracking are prone to occur, which will eventually lead to tolerances or scrap. In order to control this problem, engineers should have richer processing experience so that they can control every detail in the process.

Although there are many plastics used for CNC processing, not all materials are suitable. For example, materials with relatively low hardness are obviously too soft to be processed. Usually, experienced prototype manufacturers can make some appropriate suggestions and provide the best manufacturing solutions according to the actual needs of customers.

(2) Plastic CNC processing services used in car lights

Usually, the officially produced car light lens is a transparent PC material with high impact resistance. However, in the design and prototyping stage of many car lights, plastic CNC processing services are selected to process acrylic to make it have better aesthetics and optical effects.

Therefore, based on the above discussion, designers of automobile lights can select plastic CNC processing services according to their own design material requirements and prototype verification purposes to achieve the purpose of verifying design points.

LOW VOLUME MANUFACTURING IS THE FUTURE OF EFFICIENCY(2024年04月25日)

lcrapid — 2024-04-25T12:56:04+0900

https://www.lcrapid.com/low-volume-manufacturing-is-the-future-of-efficiency.html

1. What is low volume manufacturing?

Low volume manufacturing is referred to as part of pre-production, which is a manufacturing technique for faster mass production. The process involves manufacturing at a rate of 50 to 100,000 parts. Production depends on factors such as manufacturing process, mold tools and materials used. In addition, small-batch manufacturing is the bridge between prototyping and small volume manufacturing.

2. Low volume manufacturing process

1) New product project team

The new product project team prepares and the manager issues a new product trial production plan → relevant operating standards → relevant process documents → product design documents → pilot test qualification report → product quality outline

2) Technical process group of production department

Process engineers and product engineers compile "Process Operation Instructions" → process engineers design production process lines → equipment engineers and test engineers debug production and test equipment → product engineers and process engineers conduct new product training for production line workers → process supervisors make test production goals, organization of trial production operations and production technical support

3) Production department

The production line workers receive the ingredients according to the trial production plan for trial production → on-line production → production department technical process group engineers check whether the production line workers operate in accordance with the process requirements and the adaptability of the process route feedback → the quality department conducts a full inspection → the product is qualified after inspection success.

3. Low volume manufacturing strategy

Due to the short life cycle, frequent update iterations, and complex switching processes between varieties, small-batch manufacturing places higher requirements on the production management of manufacturing enterprises. So how to promote lean production in the low volume product industry? Quick changeover and balanced planning are the main solutions to promote lean production in low volume industries.

The solution with rapid model change and balanced plan as the main content, not only to improve on the production site, but to sort out the value flow of the entire process from the beginning of the customer order to the delivery of the product, and optimize the process of product change and improvement through the establishment of a post-complementary production mechanism, adjust the scheduling method of production orders, and finally realize a flexible production line to meet the needs of multiple varieties and low volumees of products, so that it has a digital foundation.

4. The comparison between mass production and low volume manufacturing

1) Mass production:

Mass production is usually tens of thousands, and the product needs to be opened. Large-scale processing requires molds: such as plastic molds, die-casting molds, cold stamping molds, etc. Work equipment: special fixtures such as milling fixtures, grinding fixtures, car fixtures, and drill fixtures for fitters. In short, their processing efficiency is greatly different.

2) Low volume processing:

In industrial production, issues such as materials, processes, costs, and quantities used are involved. Many parts cannot be mass-produced by machines. In this way, small-scale or small-batch processing is required through some special processes. In the middle, manual processing may also be involved in low volume manufacturing, which can save time and material costs, and speed up the product launch cycle. low volume manufacturing is inseparable from the prototype model. The prototype model is the prerequisite for low volume processing, and the low volume processing is based on the prototype model. Focusing on low volume processing can largely meet more personalized product customization.

Injection Mold Manufacturing Services
Plastic injection mold machining is a manufacturing process that requires an injection molding machine, raw plastic resin, injection mold tools.

The precision plastic injection molding process consists of the following key steps.

Step 1: The plastic resin begins as raw plastic pellets. These have been treated by drying, and then if necessary dyeing with pigments or master batch colorants.

Step 2: The pallets are fed into the machine through a funnel-shaped hopper. A reciprocating screw inside the barrel of the machine will inject these resins into the mold’s runner system.

Step 3: Resin pallets are loaded into a heated and compressed chamber called the barrel where they will be melted, forming the liquid resin.

Step 4: The melted resin enters into the mold cavity through a nozzle under high pressure.

Step 5: After the mold’s cooling and solidification, the part has been demoulded to the shape of the mold cavity.

Step 6: The mold halves (cavity or “A” side and core or “B” side) open up and a cycle begins again for the next part.

IMPACT HYDROFORMING TECHNOLOGY: NO MORE MANUAL MACHINING FOR AEROSPACE SHEET METAL FABRICATION(2024年04月25日)

lcrapid — 2024-04-25T12:49:45+0900

https://www.lcrapid.com/impact-hydroforming-technology-no-more-manual-machining-for-aerospace-sheet-metal-fabrication.html

1. Development of aerospace sheet metal fabrication (ASMF)

Among the aerospace equipment, sheet metal components are accounted for over 20% out of the total number of manufacturing workload. In contrast, high-strength aluminium, magnesium, titanium and other lightweight alloys of sheet metal components are prone to wrinkling and cracking during formation due to their low plasticity. This issue has always been plaguing the aerospace industry and hindering the light-weighting and integral development.

In particular, the manufacture of alley-complex-shaped thin-walled sheet metal components made of aluminium, magnesium, titanium with the boss, reinforcing ribs and small rounded corners has become an important issue to improve the skill level of aircraft aerospace sheet metal fabrication industry.

2. The formation of new technologies in aerospace sheet metal fabrication

In the process of ASMF operations, the correct and scientific selection of ASMF technologies can ensure the quality of the product processing, in addition to effectively regulate and guide the aerospace sheet metal fabrication working process. This is the reason that it is necessary to carry out a compelling and in-depth study of the product processing to ensure that the ASMF technology can meet the needs of sheet metal processing.

The combination of fluid-filled deep-draw forming technology and high-speed impact forming technology resulted in a new impact hydroforming technology, and a sheet impact hydraulic forming limit tester was designed from this. Through extensive experiments, it has been proven that this technology and device are also suitable for the formation of aluminium alloys, aluminium-lithium alloys, magnesium alloys, titanium alloys and other materials.

3. The role of the new technology of aerospace metal fabrication

The impacting hydroforming technology enables the formation of complex thin-walled buccal-frame components in ASMF, and the world's first production-ready impacting hydroforming device has been successfully developed based on this new principle.

This technology can change the traditional aluminium alloy sheet forming process of more than eight times of manual-assisted manufacturing process to two times of automatic production process, without intermediate process heat treatment, which can increase the production efficiency by four times, and is expected to promote and enhance the development level of aerospace sheet metal manufacture industry. Previously, the drop–weight forming technology of the Soviet Union had been inherited, which required a combination of mould pressing and manual operation, but the formed parts had defects such as scratches on the surface, low yield and poor precision and consistency.

HOW ARE CAR DASHBOARDS MADE? THESE ARE 6 INJECTION MOLDING PROCESSES YOU MUST KNOW(2024年04月25日)

lcrapid — 2024-04-25T12:48:16+0900

https://www.lcrapid.com/how-are-car-dashboards-made-these-are-6-injection-molding-processes-you-must-know.html

Ⅰ. The automotive injection molding car dashboard manufacturing process can improve the product quality
In the production of auto parts, dashboards are one of the most common auto parts requirements. Nowadays, the design of automobile dashboards is mostly produced by plastic manufacturing. With the development of automobiles in terms of safety and environmental protection, people's requirements for safety and environmental protection of automobile trims are also increasing; at the same time, more and more dashboards of car dashboard manufacturing company adopt the appearance design of seamless airbag doors, which puts forward higher and higher requirements on the manufacturing process of the dashboard.

What are car dashboards made of? Take Chevrolet's dashboard as an example. The total weight of the dashboard system is about 17KG. Its component structures mainly include: dashboard body, airbag frame, dashboard lower body, sub-instrument panel body, interior trim panel, decorative panel, wind pipe, mobile ashtray; main car dashboard material: general-purpose plastic PP+EPDM-T20, PP-T20, ABS, PC+ABS, HDPE; engineering plastic PA+30GF%, POM, etc., based on a rough calculation, the amount of modified PP accounts for 80% of the plastic used in the dashboard. If you want to improve the product quality of the car dashboard, you must pay attention to the car dashboard manufacturing process of small volume manufacturing in automotive industry.

Ⅱ. The injection molding car dashboard manufacturing process of the instrument panel

The dried plastic particles are cut in the injection molding machine through the screw and the barrel is heated and melted and then injected into the instrument panel mold to cool to obtain the finished product. Used to manufacture rigid plastic instrument panel body, blister and soft instrument panel skeleton and most other related parts. Hard plastic instrument panel materials mostly use PP, and the materials of instrument panel skeleton mainly include modified materials such as PC/ABS, PP, PPO (PPE). For other parts, ABS, PVC, PC, PA and other materials that what car dashboard made of are selected according to different functions, structures and appearance requirements.

The injection molding processing of the instrument panel can be further divided into: gas-assisted injection molding, sequence valve injection molding, compound injection molding, insert injection molding, two-color injection molding, two-shot injection molding, etc.

1. Gas-assisted injection molding

Gas-assisted injection molding is an injection molding process in which molten plastic particles are injected into the mold while a certain amount of inert gas is injected, and a specific area of the part is formed into a hollow structure through the design of the gas path, structure and process control. The hollow structure not only enhances the mechanical properties of the parts, but also reduces the wall thickness of the parts, improves the appearance of the parts, and reduces the material cost and forming cycle.

2. Sequence valve injection

Through the valve interlocked with the equipment, the opening and closing of different gates of the mold hot runner are controlled to control the injection molding process of the material flow. This process is suitable for thin-walled and long-process products, reduces the requirements for the clamping force of the equipment, optimizes the surface quality, and shortens the forming cycle.

3. Composite injection

Place a sheet that matches the shape of the mold or a shapeless sheet on the side of the movable mold of the injection mold, and then injection molding, so that the product has a two-layer structure while using the mold to give the shape. The advantage of sheet metal fabrication services is that the processing procedures are reduced, the product appearance is good, and the adhesion between parts is strong.

4. Instrument panel insert injection molding

It is more popular in the home appliance industry, and this process is used in the manufacture of electrical switches in the production of instrument panels. It is to place the metal parts that need to be embedded in the injection molded parts in the mold before injection molding, and the molten plastic after injection molding partially wraps them into parts.

5. Two-color injection molding for dashboard

On the two-color injection molding machine, different colors/types of raw materials are injected into the special injection mold at the same time/sequentially in the same production cycle, so that the product has different appearance/performance, but it is gradually being repaced by the two-shot moulding because of the huge investment in equipment and molds.

6. Double injection of instrument panel

Over-injection is an insert injection where the injection part is an insert. It is mainly used for parts with high mechanical performance and appearance requirements. Injection molding materials selection is the key to this process.

With the continuous exploration of the automotive industry in the research and development of vacuum casting applications, instrument panel materials and process improvement, automotive instrument panels will gain more and more beautiful and ergonomic appearance and experience design.

FOUR SIMPLE INJECTION MOLDING METHODS(2024年04月25日)

lcrapid — 2024-04-25T12:47:43+0900

https://www.lcrapid.com/four-simple-injection-molding-methods.html

Some factors of a part, whether material, rough, cycle time, or more, greatly affect their price. there are four tips for lowering part prices without sacrificing the components you need for success.

1.Material

By knowing what the best rapid injection molding materials for parts is, you can improve economic efficiency. The first factor in deciding which material to use is where your parts will live. Will it be outdoors, indoors, next to the oven? The durability, temperature and stability need of the parts will help meet the material what you real need. Professional Tip: A quick way to determine materials is to look at the materials of existing products running in a similar environment - no need to reinvent the wheels.

The price of the material per pound/KG will vary greatly depending on the characteristics and advantages. For example, HDPE (high density polyethylene) costs about $1.50 per pound, while materials like polysulfone cost $12-15 per pound. When you can use cheaper materials without sacrificing parts needs, you can save money by choosing the most cost-effective option.

2. Cycle time

The faster the cycle time, the less overhead each part will be. The cycle time is the time it takes for the part to form during molding. The cycle time depends on the mold build, the water circuit, and its ability to cool the plastic to solid state.

The cooling time of the part will depend to a large extent on the material you choose. As an example, HDPE cools very fast, while a material like Polysulfone needs to heat its mold and then cool it (increase cycle time). Pro Tip: If your mold needs to be heated/cooled, make sure that your mold has water circuits that will change the cycle time and appearance of the part.

Injection mold manufacturing can also set cycle times according to the material you choose. As an example, aluminum has a faster heat transfer rate, which results in faster cycle times, but aluminum can also be easily damaged, especially with complex mold geometry or plastic material types running through it. Steel takes longer to process because it has a slower heat transfer rate but is more durable.

3. Surface finish

Knowing the surface finish required for a part can reduce a lot of unnecessary costs. We've seen the customer refer to a Class A complete (mirror polishing) part, but after further discussion, it has been found that the D-1 surface treatment is equally effective (matte) for using its parts. Choose to finish according to your needs, you can save some money. We suggest that you refer to the SPI completion diagram to compare with the industry standard for roughness and determine the part that is best for you.

In conclusion, the higher the gloss you need for a part, the higher the price of the tool. Because more labor time is required to brighten the parts, which greatly saves the time and upfront costs.

LC Rapid provides a wide range of CNC surface finish for injection molding. We can also offer additional completions based on the case - just add what you need to the quote request.

4. Post-molding operation

The more you operate after styling, the more you'll have to increase your price because of the extra labor involved.

Only processing slots, holes, tapping, etc. are considered, as these will increase their costs. Design these functions into part designs and mold them.

Well-designed cooling fixtures can increase costs, but you can eliminate the need for cooling fixtures based on the material and part design of your choice.

Packing levels of the parts will reduce extra costs - if your parts are not fragile, it doesn't require additional packaging. As an example, if you don't need an egg box, gaylord is enough to protect your delivery. The same applies to the special handling requirements of your delivery.

It is also significant to decide how many special tests and tests the parts will be performed. If you are manufacturing a lot of parts, do you need to check each part? Or is it only a dozen or one-hundredth? Do you require our parts to be tested before delivery, or can you test them after receiving them? Understanding what you can do will help you save the costs.

The best way to save part costs is to understand exactly what the part is for, which will help notify you what the part does and what you don't need. Whether it's the surface finish of the part, the material, or the post-molding operation, you can reduce the costs in your choice by finding break-even points.

Common Problems and Corresponding Solutions of Injection Molding for Bumpers(2024年02月23日)

lcrapid — 2024-02-23T15:37:41+0900

https://www.lcrapid.com/common-problems-and-corresponding-solutions-of-injection-molding-for-bumpers.html

1. The application of plastic parts in automobiles is becoming more and more extensive

With the rapid development of the automotive industry, plastic parts are used more and more widely in automobiles. The application of plastic injection molding automotive parts has significant advantages in terms of reducing the quality of cars, saving fuel, promoting environmental protection, and recyclability. Most automotive plastic injection molding parts adopt injection molding processes, such as bumpers in BMW cars. However, tiger skin patterns, poor surface replication, sink marks, weld lines, warping deformation, etc. are also common defects in injection molding automotive parts. These defects are not only caused by materials, but also have a lot to do with the structural design, mold design and molding process. Here are some common problems and solutions for bumper injection molding in automotive industry.

2. Common problems and corresponding solutions of injection molding for bumpers

(1) Pressure line

There are obvious pressure lines around the bumper fog lamps, which affect the appearance and surface quality of the product. Because the bumper is part of the outer surface of the car, it has strict requirements on the apparent quality, and the pressure line will have a serious impact on its apparent quality.

Possible cause analysis and improvement measures:

a. Mold: a gate G5 is set near the hole around the fog lamp. When this gate is opened, due to the influence of the hole, the pressure on both sides of the hole will reach a balanced pressure line again.

b. Solution: try to reduce the pressure difference around the weld line, or make the pressure difference insufficient to push the solidified melt to move.

(2) Tiger skin pattern

Tiger skin pattern is a surface defect of wavy stripes, which is approximately perpendicular to the direction of melt flow, forming markings with different gloss on the surface of the part, which looks like the pattern on the skin of a tiger, commonly known as tiger skin pattern.

How to improve tiger skin pattern?

a. As for mold design, increasing the diameter of the runner and expanding the thickness and width of the gate are all effective measures to eliminate the occurrence of tiger skin patterns. The thickness of the gate is preferably 0.7 to 0.8 times that of the wall thickness, the purpose of which is to reduce the pressure loss of the melt in the runner and gate, and reduce the expansion effect when entering the cavity.

b. In the injection molding process, increasing the melt temperature and the mold temperature, and adjusting the injection speed will help eliminate the occurrence of tiger skin lines. Under normal circumstances, using a lower rate of fire is beneficial to eliminate tiger skin patterns, because the melt flow is more stable at a low speed.

(3) Material flower

The flower-like cold material near the car bumper not only affects the apparent quality of the part, but also affects its mechanical properties. The car bumper is a safety device that absorbs and relieves external impact and protects the front and rear of the body. Generally, it is better to choose PP with better mechanical strength.

Possible cause analysis and improvement measures:

As for injection molding processing, some needle valve gates may not be sealed tightly, there is residual cold material on the gate, and the air pressure for closing the needle valve is very low, which cannot play the role of sealing glue. The air pressure of the needle can be increased by using an air pressure booster, and the cold material will disappear when there is no leakage around the hot gate.

(4) Peeling

Because the surface area of automobile bumper parts is large and the defect rate of it is low, it is rather difficult to find out the peeling defects, but this defect seriously affects the surface quality of the parts.

Possible cause analysis and improvement measures:

a. Forming process: due to the manual pickup during the production process, when the pickup takes a long time, each hot nozzle will have different degrees of salivation. After shortening the pickup time, it was found that the salivation phenomenon of the hot mouth was effectively improved. Therefore, it is possible that the cold material produced by the drool is washed into the cavity, which causes the occurrence of delamination and peeling.

b. Solution: increase the injection distance of the injection molding machine so that the hot nozzle will no longer produces salivation.

CNC Cutting Services for Aluminum Profile of New Energy Automotive Industry(2024年02月23日)

lcrapid — 2024-02-23T15:32:37+0900

https://www.lcrapid.com/cnc-cutting-services-for-aluminum-profile-of-new-energy-automotive-industry.html

1. Importance of CNC cutting service for aluminum profiles

The aluminum profile production and processing process includes cutting, opening, tapping, slot milling and installation. As the key production process, the aluminum profile CNC cutting has an extraordinary effect. A piece of aluminum profile has a length of 6 meters, and generally all of them must be cut before they can be assembled and applied. The CNC plasma cutting of aluminum profiles is carried out based on the production and processing engineering drawings, and the cutting accuracy must be ensured so as not to harm the subsequent applications. At the same time, it also fully saves labor costs, saves the enterprise operating costs, promotes enterprise standardized production, and improves product quality and good rate.

2. Application of CNC plasma cutting aluminum in new energy vehicles

The density of aluminum alloy for automobiles is only 1/3 of that of steel, and it is lightweight, recyclable and easy to form. Aluminum can absorb a lot of energy when it collides, which can improve the safety of the car while reducing weight.

Lightweight and high safety have made automotive aluminum alloy battery shells the mainstream of power battery shells. The battery shell made of aluminum alloy is thinner and lighter than the steel shell. In addition, once the battery explodes, the lithium battery aluminum shell is also weaker than the steel shell in explosiveness, and the damage caused by the aluminum shell power battery is relatively lower. When producing aluminum alloy battery shells for new energy vehicles, precision plasma cutting is often used.

The battery box, liquid-cooled plate, anti-collision beam, shock absorber, new energy vehicle electrical bracket, CCB instrument panel bracket and lower body aluminum profile parts in new energy vehicles can all be made of aluminum alloy. For example, the battery box of FAW-Volkswagen cars adopts cnc plasma cutting service to improve the performance and quality of the car.

This kind of aluminum alloy sheet after CNC cutting has the following characteristics:

1) Low density

2) Excellent thermal conductivity

3) Good damping and shock absorption

4) Good corrosion resistance

3. Several ways of CNC cutting

(1) Cutting quality: excellent inclination angle and small area affected by heat. Basically no slag; excellent fine cutting effect can be achieved under the narrowest bend condition;

(2) Production capacity: The cutting torch can be quickly disengaged, which improves the production efficiency. It is extremely fast when cutting metal materials with a thickness of less than 6mm. The thicker the metal, the lower the speed, the thicker the metal, and the longer the perforation time. Generally laser cutting is used in non-metal cutting metal, only high-precision laser cutting is used.

Plasma cutting

(1) Cutting quality: excellent inclination angle, small area affected by heat, basically no slag, good to excellent fine cutting effect

(2) Production capacity: when cutting metal materials of various thicknesses, the speed is extremely fast, and the perforation speed is extremely fast

In the future, with the continuous development of CNC profile cutting services, the cut aluminum alloy sheets will have higher strength, more and more complex cavities, thinner walls, higher welding performance and lower costs.

WHAT TOLERANCES WOULD YOU WANT WHEN MANUFACTURING THE PARTS AND PRODUCTS(2023年)

lcrapid — 2023-09-18T17:22:27+0900

https://www.lcrapid.com/what-tolerances-would-you-want-when-manufacturing-the-parts-and-products.html

When you offer us the 2D and 3D drawings for quotes on new projects, you must specify the dimensions of the key areas on the part and the required industry standard sheet metal fabrication tolerances. In most cases, very strict tolerances are neither practical nor desirable, so let's focus on the tolerances that we specified for most projects at LC Rapid, why our rapid prototyping factory do this, and what it means for your parts and products.

What are sheet metal fabrication tolerances?

Tolerances are acceptable deviations away from precise measurements or dimensions. It's often expressed as a value of "+/-". If the dimensions on a given feature are 50 mm, the tolerance will be at a number slightly higher or slightly below a certain number. 50.1mm - 49.9mm represents a tolerance of 0.1mm of +/- but sometimes the tolerance is expressed as a +0/-.2. In this way, the specification states that a given feature cannot be bigger than the nominal value, but can be slightly smaller.

Since there will be many possible movements and must be explained, we should find a compromise within the shortest time frame, tolerance, and minimum costs. Perfection is impossible, so we need a standard to make parts and products.

What is ISO 2768-1 standard tolerances for sheet metal fabrication?

This is the industry standard for covering linear, flatness, radius, determining tolerances, and angular dimensions, and more. At LC Rapid, as a rapid prototyping factory, we validate our sheet metal fabrication services for tolerance classification of ISO 2768-1 fine (metal) and media (plastic). The most recent tolerance in this classification system drops to 50 microns or .002 inches. It’s very small.

That's what most of the projects we're referring to expect, and that's enough for most applications. The standard is agreed by manufacturers around the world to produce lots of parts and products every day for our customers. It’s reliable and repeatable on modern CNC machines, using high-grade materials and cutting tools, making it the bottom line for high-quality manufacturing of mass-produced products.

How will the industry standard sheet metal fabrication tolerances affect your parts and products?

What do the numbers mean for the way your section looks, feels and executes? ISO 2768-1 fine allows all features, holes, mating faces and grooves to be in the right position. The screw will smoothly enter its mating thread, no free play (too loose) or no binding (too tight). The cover will close flat with a nice uniform seam around. Parallel will will be parallel, vertical will be vertical, all degrees exceeding most normal expectations in the real world. To be honest, in most cases, you don't want to be more tolerant than this.

Why are the strict sheet metal fabrication tolerance standard not always a good thing?

All materials expand and contract with temperature. They can be deformed under load, moved by vibration, or worn over time. So, even if a feature or size is "perfect" manufactured in the factory, it’s not perfect once it is put into use. This is a reality for all objects that need some free play to combine and pull apart.

In addition, from the manufacturer's point, the pursuit of perfection in any function - such as the position of the screw hole -it means that you will lose it. In production, the small, incremental improvement of tolerances is hard to achieve in some ways. They require longer processing times specialized equipment, higher costs and climate-controlled clean rooms. Such investments may be necessary for luxury, aerospace components and watches sophisticated scientific instruments but they are rarely or desirable for rapid prototyping or low volume manufacturing.

What standard sheet metal fabrication tolerance is best for your project?

It depends on what your part and product are for and how it’s used. We can confidently say that the tolerance better than a 2768-1 fine is rarely necessary and you will improve economic efficiency and still get a big portion if you use the above recommendations as a guide. When you're ready to learn more about engineers submitting offers, our engineers are on hand to help you with the technical information.

THE WORKING PRINCIPLE OF VACUUM CASTING AND ITS ADVANTAGES OF THE THREE TYPES(2023年)

lcrapid — 2023-09-18T17:22:00+0900

https://www.lcrapid.com/the-working-principle-of-vacuum-casting-and-its-advantages-of-the-three-types.html

Vacuum die casting is a process that uses vented molds. The molten metal flows into the mold by air pressure, and then the air is purged to form a vacuum. This vacuum permanent mold casting method is mainly used for small parts or jewelry with delicate details.

1. The working principle of vacuum casting aluminum

Using vacuum casting applications is a physical modeling method that combines vacuum technology with sand mold casting, and seals the cavity surface and back of the sand mold with plastic film, generating the negative pressure with the help of vacuum pump, and the pressure difference between the inside and outside of the sand mold is caused to tighten the molding sand. Besides,the mold sand will then collapse to obtain the casting after placing the sand core, closing the mold, casting, waiting for the casting to solidify, releasing the negative pressure or stopping the air extraction.

2. The advantages of the three types of vacuum casting metal

Vacuum casting can be roughly divided into three types: vacuum suction casting, vacuum low pressure casting, and vacuum differential pressure casting:

Vacuum suction mould casting

Placing the casting mold in a closed container, and drawing out the air in the casting mold to cause a certain negative pressure in the casting mold, which will lead to the molten metal to be sucked into the mold cavity. When the ingate of the casting is solidified, removing the negative pressure, so that the unsolidified molten metal in the down gate flows back into the molten pool. The advantages are as follows:

(1) Vacuum suction casting is conducive to the elimination of gas in the mold, suppresses the generation of turbulence and air entrainment, also overcomes the disadvantages of low-pressure casting and differential pressure casting, so that improving significantly the filling capacity of molten metal.

(2) Due to the improvement of filling capacity during vacuum suction casting, the casting temperature of molten metal can be 20~30℃ lower than that of gravity casting.

(3) The castings with large wall thickness differences, thin walls and high quality requirements can be cast.

(4) A smooth filling effect can be obtained by selecting a suitable vacuum degree change rate and controlling the speed of molten metal entering the cavity.

Vacuum low pressure mould casting

The vacuum low-pressure casting method is to vacuum the mold during the vacuum die casting process of pressurizing and filling, after the filling is completed, the pressure is maintained to make the casting crystallize and solidify under a constant pressure, and then the casting gets fully fed, so that the casting structure is compact and the mechanical properties are improved. The advantages are as follows:

(1) The existence of vacuum negative pressure can compact the mold sand and increase the strength of the mold.

(2) Increasing the degree of vacuum moderately to shorten the filling time, which not only accelerates the filling speed but also stabilizes it.

(3) Vacuum low-pressure casting can accelerate the fluidity of aluminum alloy at low temperature, avoiding the phenomenon of aluminum alloy suction caused by high temperature casting, and increasing the pinhole defects of castings.

(4) The casting has good formability, which is conducive to the formation of castings with clear contours and smooth surfaces as well as large thin-walled castings.

(5) The casting such as the vacuum casting silicone mold has compact structure and high mechanical properties.

(6) Under normal circumstances, there is no need for riser, so that the yield of molten metal can be greatly improved, usually up to 90%.

(7) Good working environment and simple equipment are helpful for mechanization and automation.

3. Vacuum differential pressure mould casting

Vacuum differential vacuum die casting process is mainly to seal all the resistance holding furnace and the casting mold, and inject compressed air with a larger pressure such as 500kPa into the sealing cover. At this time, since the pressure inside the mold and the crucible is equal, the molten metal will not rise, and then add 50kPa pressure on the molten metal surface, the molten metal will rise to fill the cavity. The advantages are as follows:

(1) Compared with the traditional gravity casting and vacuum suction casting, the vacuum differential pressure casting shows a good filling ability on the 1mm thick sheet sample.

(2) The small volume manufacturing castings have denser crystalline structure and mechanical properties. In terms of the the strength of castings, it is about 20% to 25% higher than that of vacuum suction casting and gravity casting, and the elongation is about 50% higher.

(3) Vacuum die casting can effectively reduce the pores of die castings and increase the density of castings by more than 1%.

As a rapid prototyping factory, we will do our best to meet all the needs of customers.

There are many pressure die casting dies manufacturers in China, but we are one of the best choices for you.

https://www.lcrapid.com/the-introduction-to-3d-stereolithography-sla.html

The most commonly used technology in 3d printing in automotive industry is stereolithography, which is applied to create models, prototypes, patterns, etc. Next, we will introduce 3D stereolithography technology to you.

I. What is 3D stereolithography (SLA)

Research in the field of 3D stereolithography was carried out in the 1970s, but the term was created by Chuck Hull in 1984. At that time, he applied for a patent for the process, which was granted in 1986. 3D stereolithography can be used to manufacture products such as product prototypes, medical models, computer hardware and many other applications. Because stereolithography technology can print fast and generate almost any design, SLA series molding machines occupy a large share of the 3D printing and manufacturing equipment market.

SLA process is based on the principle of photopolymerization of liquid photosensitive resin. Under the irradiation of UV light with a certain wavelength (325 or 355 nm) and intensity (w =10-400mw), this liquid material can rapidly undergo photopolymerization reaction, and the molecular weight increases rapidly, then the material changes from liquid to solid. The liquid bath is filled with liquid light-cured resin. The laser beam can scan on the liquid surface under the action of the deflecting mirror. The scanning track and the presence or absence of laser are controlled by computers. The place where the liquid is scanned by the light spot will solidify. At the beginning of molding, the working platform is at a certain depth below the liquid surface, and the liquid surface is always in the focal plane of the laser. After focusing, the light spot will scan the liquid surface point by point according to the instructions of the computer, that is, point-by-point solidification. When a layer of scanning is completed, the unexposed area is still liquid resin. Then the lifting platform drives the platform one layer down, and the formed layer is covered with another layer of resin. The scraper will scrape the resin liquid level with high viscosity evenly, and then the scanning of the next layer will be continued. The newly solidified layer will firmly adhere to the previous layer. This process will be repeated until the whole part is manufactured, and a three-dimensional solid model will be obtained.

II. A brief history of stereolithography

Stereolithography is an early widely used 3D printing technology. In the early 1980s, Hideo Kodama, a Japanese researcher, first invented the modern layered stereolithography technology by using UV-cured photosensitive polymers.

However, the term stereolithography was created by Chuck Hull when he submitted the patent of the process in 1984. The patented stereolithography technology of Chuck Hull is a method to create 3D objects by continuously printing thin layers of objects from the bottom to the top using a medium that can be cured by UV light. Hull's patent describes a process that a beam of concentrated ultraviolet light focuses on the surface of a barrel filled with liquid photopolymers. The beam focuses on the surface of the liquid photopolymer, and each layer of the desired 3D object is produced by crosslinking (creating intermolecular bonds in the polymer). His invention aimed to enable engineers to create prototypes of their designs in a more efficient way. After obtaining a patent in 1986, Hull co-founded 3D Systems, the first 3D printing company in the world, and commercialized it.

The success of stereolithography technology in the automotive industry has established the industry status of 3D printing, and innovation uses of this technology is continuously applied in many research fields. Now we are trying to build a mathematical model of the stereolithography process and design algorithms to determine whether 3D printing and manufacturing can be used to construct the proposed object.

III. Why choose SLA 3D printing?

1. It has the longest development history, the most mature technology and the most extensive application. Among the rapid molding machines installed all over the world, the UV-cured molding system accounts for about 60%.

2. The molding speed is fast and the system is stable.

3. It is highly flexible.

4. The precision is very high, which can achieve micron level, such as 0.025mm.

5. Good surface quality and smoothness make it suitable for fine parts.

IV. Material types commonly used in stereolithography

1. Engineering plastics

Engineering plastics are widely used 3D printing materials applied to FDM equipment. They are plastics with excellent strength, impact resistance, heat resistance, hardness and aging resistance. Engineering plastics include thermoplastic materials and thermosetting materials.

2. Photosensitive resin

Photosensitive resin is generally in a liquefied state, and objects printed with this material generally have high strength, high temperature resistance, water resistance and other characteristics.

The specific characteristics of photosensitive resin are as follows: low viscosity; small curing shrinkage; fast curing rate; small swelling; high photosensitivity; high curing degree; high wet strength. The properties are stable before curing, which makes the transportation and storage easy, and there is no dark reaction. Due to its fast curing speed, the photosensitive resin has excellent surface dry property, and the product appearance is smooth after molding, which can be transparent to translucent frosted. Due to its good liquid fluidity and instantaneous photocuring property, liquid photosensitive resin has become the preferred material for stereolithography consumables in high-precision product printing.

3. Metal materials

Metal materials for stereolithography exist in the forms of metal powder, metallic foil and metal wire. At present, the market share of metal materials is small, but the expansion speed is fast. If metal materials are added to some engineering plastic materials (such as ABS), wires with certain metal properties that are suitable for FDM models can be made.

4. Ceramic materials

Aluminosilicate ceramic powder can be used for the stereolithography of ceramic products. Ceramic powder is usually in powder form and generally used in selective laser sintering (SLS) printers. The ceramic powder for stereolithography is a mixture of ceramic powder and a certain binder powder.

Ceramic materials have the advantages of high strength, high temperature resistance and corrosion resistance, which enable them have potential applications in aerospace and automotive fields. At the same time, there are various colors of ceramic materials for selection, so vivid and colorful products can be printed with ceramic materials. Ceramic materials are ideal choices for handicrafts, architecture and sanitary products.

Compared with the traditional manufacturing technology, the ceramic stereolithography technology using ceramic materials has faster molding speed, is free from the shackles of the mold, and does not depend on the complexity of the parts; the traditional ceramic manufacturing technology can only produce products with simple structures, and has the disadvantages of high cost and long production cycle. Instead, the ceramic stereolithography technology can make up for the shortcomings of traditional ceramic manufacturing technology with its simple operation, high speed and high precision. At present, ceramic stereolithography technology is mainly used in industrial products, jewelry / luxury goods, medical industry, etc. Of course, it is also an essential technology for universities and research institutes engaged in scientific research.

5. High polymer materials for biological use

High polymer materials for biological use mainly include scaffold materials and direct cell printing materials. Scaffold materials should meet the following requirements: They shouldhave good biocompatibility but no toxicity to cells and body; good biodegradation characteristics ensure that they can be completely degraded and absorbed by the body or excreted from the body; the materials should have good mechanical properties, certain mechanical strength and plasticity, so the structure can be stable for a long time with high porosity; a good surface compatibility is conducive to cell adhesion and growth on the material surface.

V. Applications of SLA 3D printing

SLA 3D printing technology can be used in product development and the creation of prototypes (concept, geometry, vision, functional model) in mechanical engineering, especially in automobile industry and medicine.

Since the 1990s, stereolithography models have been used in medicine to create accurate 3D models of various anatomical regions of patients based on data from computer scanning. Stereolithography models can also be used in auxiliary diagnosis, preoperative planning as well as implant design and fabrication.

It is expected that the use of stereolithography equipment in the direct production of terminal products (rapid manufacturing) will increase in the next few years.

As a rapid prototyping factory, LC Rapid offers a complete turnkey solution for achieving the perfect engineering surface finish. We offer a broad spectrum of industrial finishing services, from anodizing to plating, sanding to painting, such as aerospace anodizing, automotive powder coating and industrial powder coating. we can complete whatever finishing that tailored to exceed your expectation by CNC surface finish. We are not simply manufacturing experts, we are also experienced in achieving the desired color, texture, and luster.

Surface Finishing Process

Plating

Plating and metal finishing services is the process of applying one or more layers of a metal to a part. Plating improves strength, wear resistance, lubricity and cosmetic appearance on parts. Many industries use the plating process, including the medical, aircraft, automotive, electronics, mechanical, diagnostic, and etc.

Sanding and Brushing

Sanding is used to remove the machining cutter marks, burrs, and etc. Sanding typically starts with a coarse grit paper to quickly remove surface imperfections and follows with the finer grit to improve the surface quality. Sanding is applied to reduce the roughness, get a cosmetic appearance, make the preparation for later plating or painting.

We can also provide a brushed and non-mirror-like metallic effect for a handful of metals such as aluminum, steel, copper, and bronze. The brushing process is to grind the surface to achieve the unidirectional satin finish with 120 grit - 180 grit paper or 80 grit -120 grit abrasive belts.

Blasting

Blasting can be used to remove machine marks, surface deposits, scratches and other surface imperfections by spraying the abrasive materials against surface of your part with the aid of compressed air. The abrasive materials we use include sand, garnet, walnut shells, glass beads, and high-pressure water. Blasting can also improve some of the mechanical properties of metal, such as shot-penning is a process deigned to enhance fatigue strength and improve corrosion resistance.

Polishing

Polishing is the process of reducing the surface roughness by utilizing physical rubbing or chemical agent to obtain a high quality smooth and bright surface. Polishing can get a shiny or mirror look that improve the final surface of the product. Polishing is generally for aesthetic purposes.

Vapor Polishing

Vapor polishing is a frequently-used method for achieving optical clarity on plastic for most applications. This process utilizes a chemical vapor that melts the surface of the plastic, causing it to flow. Both internal and external features can be polished to be transparent by applying vapor polishing. The surface of parts doesn’t have any dust, water, scratch, etc. Usually, the vapor polishing is not more than three times, because vapor polishing too many times will generate a crack on the PC materials.

Powder Coating

Powder coating services excellent durability, corrosion and wear resistance onto the surface. The process is completed by spraying the powder particles on the surface of the work piece from the powder spraying machine. Powder coatings can gives you a wide variety of color selections similar as the painting finish. Customers can specify colors which can match color reference number in PANTONE or RAL or provide us with the physical color sample to match.

Anodizing

There are many advantages to choose advanced anodizing options on aluminum anodizing chemicals，such as non-ferrous metals, aluminum, magnesium or titanium. Aluminium anodizing process is popular to provide good corrosion resistance and wear resistance, increase surface hardness. The parts will be more durable and long-lasting after being anodized. Through electrochemical oxidation, the defects of the surface can be removed, thus improving the cosmetic appearance of the metal surfaces. Anodized parts can be seen in a wide range of industries, from electronic, automotive, to telecommunication, aerospace industry.

We are aluminum anodizing manufacturers, offering aluminum anodizing colors or clear (type II) and Anodizing hard coat (type III).

Type II anodizing allows us to get different colors on parts.

Type III anodizing is also suitable for functional applications that require excellent durability and hardness.

Painting

The painting process is completed by spraying the paint on the surface of the work piece from the spraying machine. Our experienced painters can supply virtually any colors, in matte, satin, high gloss, metallic or soft-touch (rubber-like effect). We can even create custom textures according to customers' requirements. After painting, you can get a aesthetic and uniform-coated appearance. The painted parts have many benefits. Painting can serve as protection for the parts.

Painting can be used to coat both metal and plastic parts.

https://www.lcrapid.com/stainless-steel-pumps-can-be-manufactured-with-stainless-steel-cnc-machining-services.html

1. CNC stainless steel machining is widely used

Stainless steel shows advantages in corrosion resistance and wear resistance, and the finished stainless steel has high strength and toughness. It is widely used in mechanical equipment, molds and other fields. The stainless steel part is a key component of a certain mechanical equipment and requires high precision.

Precision CNC stainless steel processing parts have become the first choice in many industries due to their good physical properties. Stainless steel has become one of the most popular industrial alloys in many processing projects due to its excellent physical properties. The best and fastest way to manufacture stainless steel parts is CNC machining. Stainless steel CNC machining services have a very wide range of processing.

2. Stainless steel CNC custom machining services for stainless steel pumps

1) Introduction of stainless steel water pump

All flow parts of the stainless steel water pump series are made of stainless steel, with good corrosion resistance, using hard alloy bearings and mechanical seals, and rigid coupling transmission. Stainless steel water pump has the characteristics of small size, light weight, corrosion resistance, low vibration, low noise, small footprint, long service life, beautiful appearance, etc., especially high efficiency and energy-saving property.

In the production of stainless steel water pumps, stainless steel CNC machining services are often adopted. For example, the famous Siemens stainless steel water pump has CNC processing on stainless steel materials during the manufacturing process to improve its performance.

2) Advantages of CNC stainless steel processing service

When machining parts are changed, generally only the NC program needs to be changed, which can save production preparation time.

Mass production, product quality is easy to control.

The machine tool itself has high precision and high rigidity, can choose a favorable processing amount, and has high productivity (generally 3 to 5 times that of ordinary machine tools).

Multi-coordinate linkage can be carried out, and parts with complex shapes can be processed.

It has high processing precision and high processing quality.

The machine tool has a high degree of automation, which can reduce labor intensity.

3) Advantages of the stainless steel water pump after CNC stainless steel processing:

Compact structure and small space occupation.

The stainless steel pump can be directly installed in the sewage tank because it is submerged in the liquid. There is no need to build a special pump room to install pumps and machines, which can save a lot of land and infrastructure costs.

There are no problems such as cavitation damage and irrigation.

Especially the latter point brings great convenience to the operators. But everything is divided into two. The most critical issue for stainless steel pumps is the availability. Because stainless steel pumps are used under liquid; the conveying medium is some mixed liquid containing solid materials; pump and motor Very close; the pump is arranged vertically, and the weight of the rotating parts is in the same direction as the impeller receiving water pressure. These problems make stainless steel gear pumps have higher requirements than ordinary sewage pumps in terms of sealing, motor load capacity, bearing arrangement and selection.

Easy maintenance.

Small stainless steel gear pumps can be installed easily, and large stainless steel gear pumps are usually equipped with automatic coupling installations that can stop automatic devices, which are quite convenient for installation and maintenance.

Long continuous operation time.

Because of the coaxial of the pump and the motor, the stainless steel gear pump has a short shaft and light-weighted rotating parts, the load (radial) on the bearing is relatively small, and the service life is much longer than that of ordinary pumps.

PROCESS FLOW AND APPLICATION OF DIE CASTING(2023年)

lcrapid — 2023-09-18T17:19:11+0900

https://www.lcrapid.com/process-flow-and-application-of-die-casting.html

Pressure die casting is a metal casting process, which is characterized by applying high pressure to the molten metal using the cavity of the mold. The die casting mold is usually processed with a higher strength alloy. Pressure die casting is particularly suitable for manufacturing a large number of small and medium-sized castings, so die casting is the most widely used one among various casting processes. Compared with other casting technologies, the die-casting surface is flatter and has higher dimensional consistency.

1. Design of Die Casting Mould
Die casting mold is an important process equipment in die casting production, and its design will directly affect the quality of die casting results.

The following points should be paid attention to when designing die casting mold:

(1) Use advanced and simple structure as much as possible to ensure stable and reliable operation and daily maintenance and repair.

(2) The modifiability of the gating system should be considered, and necessary modifications can be made during the debugging process.

(3) Reasonably select various tolerances, scales and machining allowances to ensure reliable mold fit and required die casting accuracy.

(4) Choose suitable mold materials and reliable heat treatment technology to ensure the service life of die-casting molds.

(5) It should have sufficient rigidity and strength to withstand the clamping pressure and expansion force without deformation during the die-casting production process.

(6) Use standardized die casting mold parts as much as possible to improve economy and interchangeability.

When designing the mold, it is necessary to calculate the total projected area and specific injection pressure during die-casting production according to the projected area of the casting to select a die-casting machine of suitable tonnage. The formula is as follows:

F expansion force = 100 P injection specific pressure × S projection area

F clamping force = F expansion force / K factor

2. Die casting process
The traditional die-casting process is mainly composed of four steps. The four steps include mold preparation, filling, injection, and sand falling. They are also the basis of various improved die-casting processes.

During the preparation process, a lubricant needs to be sprayed into the mold cavity. In addition to helping to control the temperature of the mold, the lubricant can also help demold the casting. Then you can close the mold and inject the molten metal into the mold with high pressure. The pressure range is about 10 to 175 MPa. When the molten metal is filled, the pressure will be maintained until the casting solidifies. Then the push rod will push out all the castings. Since there may be multiple cavities in a mold, multiple castings may be produced during each casting process. The process of falling sand requires separation of residues, including mold openings, runners, gates and flash. This process is usually done by extruding the casting with a special trimming die. Other methods of falling sand include sawing and sanding. If the gate is fragile, the casting can be beaten directly, which can save manpower. The excess mold opening can be reused after melting. The usual yield is about 67%.

3. Pressure Die Casting Applications
Die-casting has high production efficiency and can die-cast parts with complex shapes, precise dimensions, clear outlines, high surface quality and strength, and hardness, so it is widely used and developed rapidly. The die-casting process has a wide range of uses and is widely used in the production of daily production equipment and consumer goods. Globally, 60% of die-casting parts are used in automobile manufacturing. For example, various parts of Mercedes-Benz cars also use the die-casting process.

TWO TYPES OF PRESSURE DIE CASTING AND THEIR ADVANTAGES(2022年12月18日)

lcrapid — 2022-12-08T17:16:49+0900

https://www.lcrapid.com/two-types-of-pressure-die-casting-and-their-advantages.html

TWO TYPES OF PRESSURE DIE CASTING AND THEIR ADVANTAGES

Pressure die casting is a metal casting process, which is characterized by applying high pressure to the molten metal using the cavity of the mold. Molds are usually made of higher-strength alloys. This pressure die casting process is somewhat similar to injection molding. Our pressure die casting china is mainly divided into two types: high pressure die casting and low pressure die casting.
1. High Pressure Die Casting

The essence of high pressure die casting is to fill the cavity of a high pressure die casting mold (die-casting mold) with liquid or semi-liquid metal at a higher speed under high pressure, and form and solidify under pressure to obtain castings. Its commonly used injection pressure is from several thousand to several ten thousand kPa, even as high as 2×105kPa. The filling speed is about 10~50m/s, and sometimes even more than 100m/s. The filling time is very short, generally in the range of 0.01 to 0.2s.

2. Advantages of Pressure Die Casting

1) Good product quality;

2) Its productivity is high, and the die-casting mold can be used for many times;

3) Good economic benefits;

High pressure die casting products are very common in the automotive industry. For example, bearing retainers, cylinder blocks, cylinder heads and oil pump bodies in BMW cars can all be manufactured by high pressure die casting.

3. Low Pressure Die Casting

Low pressure die casting is a casting method in which liquid metal completes the filling and solidification process under pressure to obtain castings. Its acting pressure is relatively low (generally 20~60kPa).

4. Advantages of Low Pressure Die Casting

1) The filling speed can be accurately controlled, and the filling of liquid metal is relatively stable;

2) High metal utilization rate and low material cost;

3) Low labor intensity and good working conditions. The equipment is simple, it is easy to realize mechanization and automation, and is not affected by the proficiency of the operator;

4) Bottom injection type filling is used to improve the qualification rate of castings;

5) There are few internal defects; less gas and debris are involved; and the castings are dense.

Low pressure die casting is suitable for manufacturing products with medium wall thickness and high-performance requirements, such as chassis safety parts for Ford cars.

The medical device industry and CNC precision machinery processing industry are highly related industries that promote each other and develop in coordination. There are many medical equipment R&D companies and many CNC processing manufacturers. Medical equipment companies are often interested in product research and development, and considering a large number of mold opening risks, they will find some regular CNC processing manufacturers to cooperate, and require some CNC precision machining models to be produced first, which can be assembled and used, and the effect is verified first. This will test the raw material molding technology of CNC processing manufacturers.

Many small medical device model factories are definitely not up to standard in accuracy and do not meet customer needs. So they found our CNC processing plant to handle this difficult situation well, thanks to the provision of multiple five-axis processing machines. The accuracy can reach +0.01mm, which can meet the requirements of customers on 3D drawings. If you are worried that the use environment will affect the product, the professional project manager of our technical department will negotiate with the customer to come up with a plan, and then select the use of raw materials.

ALUMINUM EXTRUSION ACCESSORIES OF DIFFERENT SPECIFICATIONS FOR MEDICAL DEVICES(2022年12月15日)

lcrapid — 2022-12-08T17:15:19+0900

https://www.lcrapid.com/aluminum-extrusion-accessories-of-different-specifications-for-medical-devices.html

1. Aluminum extrusion parts are an important component of medical equipment
The production of aluminum extrusion parts will use an extrusion process. This process uses the original form of aluminum to heat the billet to a specified temperature. At this temperature, the aluminum becomes soft and ductile, and then it is transferred to the press container. The press presses the aluminum billet through the container by applying greater pressure and squeezes it through the final shape of the die. Then, the extruded parts pass through various stations, where they can be cooled, stretched and cut to the required length.

Aluminum extrusion parts are one of the important materials for building medical aluminum frame structures. When assembling various medical aluminum products, you must also use the matching aluminum extrusion parts. It can be seen that aluminum extrusion parts are useful for medical aluminum products. It has a great influence, so when choosing aluminum extrusion parts for medical devices, it is necessary to put forward higher requirements for its quality.

2. Aluminum extrusion parts of different specifications for medical devices

Aluminum extrusion parts for medical devices are classified according to specifications. Generally, 1010 aluminum extrusion, 1515 aluminum extrusion, 3030 aluminum extrusion, 3060 aluminum extrusion, 4020 aluminium extrusion, 4040 aluminum extrusion and 4080 aluminum extrusion can be used.

There are many commonly used medical aluminum accessories, and the specifications and materials of each accessory are different, and the connection methods are also various. Medical aluminum is light in weight, and there are various types of medical aluminum accessories, which can basically meet the needs of users. Common medical aluminum accessories include bolts, nuts, corner pieces, connectors, end connection plates, spacer connection blocks, and elastic buckles. For example, Medtronic's medical trolley uses aluminum extrusion parts.
3. Medical aluminum production process

1) Casting

Casting is the first process of aluminum machining. Electrical appliance profiles are mainly used in various fields such as bus bars, overhead wires, conductors, electrical components, refrigerators, air conditioners, and cables.

The important processes are:

Ingredients: According to the specific alloy grades to be produced, calculate the increase of various alloy components, and match various original materials reasonably.

Smelting: The prepared raw materials are added to the melting furnace according to the process requirements for melting, and the slag and gas in the melt are effectively removed by degassing and slagging refining methods.

Casting: Under a certain casting process, the molten aluminum is cooled and casted into round casting rods of various specifications through a deep well casting system.

2) Extrusion

Extrusion is a means of forming profiles. First, design and manufacture a mold according to the profile product section, and use an extruder to extrude the heated round cast rod from the mold. Commonly used 4080 aluminum profiles require an air-cooling quenching process and subsequent artificial aging process during extrusion to achieve heat treatment strengthening. Different specifications of heat-treatable and strengthened alloys have different heat treatment systems.

3) Coloring

Oxidation: The extruded medical aluminum has a weak surface corrosion resistance and must be treated by anodizing to increase the corrosion resistance, wear resistance and aesthetic degree of the aluminum.

Under the guidance of high quality standards, the aluminum extrusion technology of LC Rapid carries out strict quality control over the entire manufacturing process. We conduct regular tests and verifications at all stages of manufacturing to ensure that we deliver excellent quality products every time.

https://www.lcrapid.com/3d-printing-mold-is-the-future-of-lowvolume-injection-molding-production.html

In the past, the molds used for injection molding were usually made of steel or aluminum, and used reducing material manufacturing technology, such as CNC machine tools. But recently, more companies have tried to use more advanced 3D printing processes to simplify the mold making process. This technology is very suitable for low volume injection molding.

3D PRINTING & MOLD IS THE FUTURE OF LOW-VOLUME INJECTION MOLDING PRODUCTION
Date: Dec 11 2020 | By:LC Rapid
Tag:3D Printing, Low-volume Manufacturing,
In the past, the molds used for injection molding were usually made of steel or aluminum, and used reducing material manufacturing technology, such as CNC machine tools. But recently, more companies have tried to use more advanced 3D printing processes to simplify the mold making process. This technology is very suitable for low volume injection molding.

1. Why do we need to perform low volume plastic injection molding?
At the moment when the customer market is changing, a new product is mass-produced without market verification, which is extremely risky. The significance of low-volume injection molding is: first small-scale production to verify market demand, and then mass production under the condition of market approval, this method is obviously more secure. For example, when a new type of Apple computer heat sink is developed without market verification, a low-volume injection molding process can be performed first, and then a large number of them can be put into the market after testing.

2. Low-volume injection molding process
In the low volume plastic molding process, 3Dprinting and manufacturing may be a better choice. Unlike the vacuum compound mold, the injection mold can be used repeatedly more than 100,000 times, so usually only one mold is needed. The low-volume injection molding process is as follows:

First, we need to make a mold, usually using 3D printing technology to make it. After the mold is made, the granular injection material is turned into a liquid by hot melting, and then the liquid is compressed and injected into the cavity of the mold, solidified quickly and then ejected. The production time of each part depends on its size and the materials used. From small and simple to large and complex designs, the required unit production time may range from a few seconds to two minutes.

3. The cost of low-volume injection molding
The molds printed by 3D printing technology make the process of low-volume injection molding cheaper. Compared with other processes, the unit price is significantly lower, and prototypes and samples can be manufactured faster, or low-volume production at reasonable cost.

The Working Principle of Vacuum Casting and Its Advantages of the Three Types(2022年11月18日)

lcrapid — 2022-11-11T18:07:36+0900

https://www.lcrapid.com/the-working-principle-of-vacuum-casting-and-its-advantages-of-the-three-types.html

Vacuum mould casting is a process that uses vented molds. The molten metal flows into the mold by air pressure, and then the air is purged to form a vacuum. This vacuum permanent mold casting method is mainly used for small parts or jewelry with delicate details.

1. The working principle of vacuum casting

vacuum-casting-1.jpg

2. The advantages of the three types of vacuum casting

Vacuum casting can be roughly divided into three types: vacuum suction casting, vacuum low pressure casting, and vacuum differential pressure casting:

Vacuum suction mould casting

(2) Due to the improvement of filling capacity during vacuum suction casting, the casting temperature of molten metal can be 20~30℃ lower than that of gravity casting.

(3) The castings with large wall thickness differences, thin walls and high quality requirements can be cast.

(4) A smooth filling effect can be obtained by selecting a suitable vacuum degree change rate and controlling the speed of molten metal entering the cavity.

vacuum-casting-2.jpg

Vacuum low pressure mould casting

The vacuum low-pressure casting method is to vacuum the mold during the vacuum casting process of pressurizing and filling, after the filling is completed, the pressure is maintained to make the casting crystallize and solidify under a constant pressure, and then the casting gets fully fed, so that the casting structure is compact and the mechanical properties are improved. The advantages are as follows:

(1) The existence of vacuum negative pressure can compact the mold sand and increase the strength of the mold.

(2) Increasing the degree of vacuum moderately to shorten the filling time, which not only accelerates the filling speed but also stabilizes it.

(4)The casting has good formability, which is conducive to the formation of castings with clear contours and smooth surfaces as well as large thin-walled castings.

(5) The casting such as the vacuum casting silicone mold has compact structure and high mechanical properties.

(6) Under normal circumstances, there is no need for riser, so that the yield of molten metal can be greatly improved, usually up to 90%.

(7) Good working environment and simple equipment are helpful for mechanization and automation.

3. Vacuum differential pressure mould casting

Vacuum differential pressure casting is mainly to seal all the resistance holding furnace and the casting mold, and inject compressed air with a larger pressure such as 500kPa into the sealing cover. At this time, since the pressure inside the mold and the crucible is equal, the molten metal will not rise, and then add 50kPa pressure on the molten metal surface, the molten metal will rise to fill the cavity. The advantages are as follows:

(1)Compared with the traditional gravity casting and vacuum suction casting, the vacuum differential pressure casting shows a good filling ability on the 1mm thick sheet sample.

(2)Vacuum die casting can effectively reduce the pores of die castings and increase the density of castings by more than 1%.

Vacuum Casting
Vacuum Casting is a mid-to-low production volume manufacturing process in which a liquid polyurethane material is filled into a silicone mold, and then the plastic part can be produced in a vacuum chamber. We produce parts with showroom quality out of polyurethane material which is plastic-like and rubber-like material. These materials have the properties close to real injection moulding plastics, such as ABS, PP, POM, PC, PMMA (Acrylic), Rubber, etc. We can also offer a wide range of finishing services to exceed your desired look. Typically, a silicone mold can cast about 15-25 parts in a fast turn-around and with cost-effectiveness, which make vacuum casting a better choice over other plastic manufacturing process like injection molding.
