Plastic Injection Mould Tooling
Plastic molds are tools that are matched with plastic mold makers in the plastic processing industry to give plastic products a complete configuration and precise dimensions. Due to the wide variety of plastics and processing methods, and the complex and simple structures of plastic mould fabrication making machines and plastic products, the types and structures of plastic molds are also diverse.

What Is A Plastic Mould Tooling ?
Injection molding tooling is at the heart of plastic injection mold making. Whether it’s a complex operation or simple part, plastic mould tooling – more specifically, tooling design – determines the quality of the injection molding process and the parts produced.

Scientific molding is crucial. It provides largely accurate process of plastic injection mould making that lead to top- quality corridor with constantly tight forbearance and unremarkable confines.

Injection molders and toolmakers experienced in the application and use of scientific molding help clients steer away from arbitrary injection molding tooling design decisions in favor of data-based precision. It sounds elementary, but the factors that could skew injection mould tooling design, engineering, and outcomes are numerous. Engineers specially trained in scientific plastic injection mold making can readily identify and help prevent potential missteps.

Plastic Mould Trial Tooling Capabilities
Plastic injection molds are used when there is a requirement for male or female threads on a plastic component.

An assembly of heated components used to inject molten plastic into the cavities of the injection molding mold.

Includes mechanical action incorporated into the design when a hole, slot, undercut or thread is needed that is not perpendicular to the parting line.

Provides one parting line and the plastic injection moulds splits into two halves; the sprue, runners, gates and cavities are all on the same side.

Plastic Mould Tooling Protection Investment
Preventative：Once a injection molding mould has run a set number of cycles, examinations, conservation and cleaning should be performed. Different types of mold in injection molding age at different rates, so scheduling conservation needs to be proved precisely. Our knowledge and experience gives us the capability to determine the stylish mold conservation schedule specific to each injection moulding mold.

Maintenance：Injection molding tool repairs can be costly. This means it is critically important for injection molds to receive regular maintenance; this is simply the best way to protect your investment and maintain consistent production of quality plastic components. With our on-site plastic injection mould tooling facility we provide quick and efficient mold repairs or revisions.

How To Make Injection Molds?

Injection molding is by far the most protean of all injection molding ways. The presses used in this process vary in size and are rated grounded on pressure or heftiness. Larger machines can injection earth auto corridor. Lower machines can produce veritably precise plastic corridor for surgical operations. In addition, there are types of injection moulds that can be used in the plastic molding and manufacturing process, adding its inflexibility for contrivers and masterminds.The process itself is fairly straightforward; still, there are numerous advancements and customization ways that can be used to produce the asked finish and structure. Plastic injection molds, which are generally made from sword, contain depressions that will form the corridor. Melted plastic is fitted into the earth, filling the depressions. The mold is cooled, and the corridor are ejected by legs. Injection moulding raw material list can be varied.

This process is analogous to a jello mold which is filled also cooled to produce the final product.The mold making costs in this system are fairly high; still, the cost per part is veritably provident. Low part cost along with resin and finish options have all contributed to injection molding’s fashionability in moment’s manufacturing geography.

As a professional plastic injection molding factory, we complete all plastic injection mould making, from cutting materials to cavity carving, and then to the final assembly. We have advanced high-speed milling machines, electric discharge machines, wire cutting machines, and engraving machines to ensure that the machining accuracy can meet the requirements.

Mold Making
Mold Trial
Generally, the mold is not directly regarded as the final product when it is designed, because it will have such or other defects after it is produced. However, this type of defect There is no guarantee that they will be completely avoided before manufacturing. During the manufacturing process, there may be phenomena that cannot be stored and processed. Therefore, it is necessary to go through the trial model, and then analyze, evaluate and optimize the samples produced by the trial model to meet the requirements. High quality requirements. However, most of the defects of plastic mould tooling products are caused during the plasticization and injection molding stages, and may also be caused by improper manufacturing of plastic molds. Therefore, in order to avoid product defects caused by mold design in injection molding process steps, it is necessary to analyze when making molds. Mold design and process parameters.

Mold Trial
Sample Confirmation
The acceptance of the part shall be carried out at least 16 hours after the completion of the molding of the plastic part or the required post-treatment.

1. Inspection of product matching size

The matching dimensions of injection molding mold products refer to the matching dimensions between products or between injection moulding products and related components, including partial matching dimensions and overall relative position dimensions.

2. Trial assembly inspection

When the inspections of basic dimensions, external dimensions, and matching dimensions are completed and the design requirements are basically met, trial assembly inspection can be carried out. This is a very important means in product inspection. It can verify the matching dimensions and verify the space surface.

3. Injection molding quality inspection

When the pre-installation meets the requirements, the apparent quality of the part needs to be comprehensively inspected. At this time, the apparent quality refers to whether the apparent quality meets the requirements under the condition that there are no common defects.

The plastic injection moulding product is easy to update, and it can be made into complex shapes. Parts, injection molding/injection moulding is suitable for mass production and plastic molding processing fields such as products with complex shapes.

Plastic Injection Molding Basics
Keyplast plastic injection molding is a molding process that two metal mold halves (called core and cavity) come together and manufacture a formed part by injecting plastic materials into the cavity at a predetermined temperature and pressure, until left to cool and solidified to the shape of the mould.

As a professional injection moulding business in the plastic injection molding field, Keyplast plastic injection molding manufacturer not only provides different types of injection mold toolings such as double shot molding, insert injection molding, overmolding injection molding and materials used in injection moulding with competitive injection molding prices, but offers custom injection molding as well.

Plastic Injection Molding Process
Plastic injection molding is the process of melting plastic particles (thermosetting/thermoplastic polymers) and, once malleable enough, injecting them under pressure into a mold cavity, filling and curing to produce the final plastic injection moulding products.

How Does Plastic Injection Molding Work ?
The molding machine heats the plastic to a liquid state. The nozzle of the plastic injection machine then injects the melted plastic into the mold (injection pressure). The cavity of the mold is filled with plastic fluid and then cool to form a solid plastic molded product.

Plastic Injection Molding Technology
01
Cylinder temperature
The temperature that needs to be controlled during the injection plastic moulding process includes the temperature of the barrel, the temperature of the nozzle and the temperature of the mold, etc.

02
Nozzle temperature
The nozzle temperature is usually slightly lower than the maximum temperature of the barrel during the injection molding processs of plastic mold tooling, this is to prevent the "salivation phenomenon" that may occur in the straight-through nozzle of the molten material.

03
Mold temperature
The mold temperature has a great influence on the internal performance and apparent quality of the plastic mould tooling. The temperature of the mold depends on the crystallinity of the plastic, the size and structure of the product, and the performance requirements.

04
Injection pressure
In the current production of plastic injection moulding for sale, almost all the injection pressure of the injection machine is based on the plunger or the top of the screw to the plastic.

05
Plasticizing pressure (back pressure)
When using a screw injection machine to produce injection moulds for sale, the pressure on the top of the screw when the screw rotates and retreats is called plasticizing pressure, also known as back pressure. The size of this pressure can be adjusted by the overflow valve in the hydraulic system.

FOW1 — 2024-06-06T15:30:59+0900

https://www.key-plast.com/injection-molding-surface-finish/

Injection Molded Parts Surface Finish
Do not use the finest whetstone, sandpaper, or abrasive polishing paste at the beginning of mold polishing, as you can't throw away the rough lines. The living surface polished in that way looks very shiny, but when you take a side view, the rough lines appear. Therefore, it is necessary to polish from coarse whetstone, sandpaper or abrasive polishing paste, then change to finer whetstone, sandpaper or abrasive polishing paste for polishing, and finally polish with the finest abrasive polishing paste. This seems to be cumbersome and there are many processes. In fact, it is not slow. One process after another, the rough processing lines in the front are polished off, and then the following plastic injection molding china process step is carried out without rework, and the plastic injection molding surface finish can meet the requirements with one step.

Textured Finish
Industrial injection molding finishing is to create various patterns on the surface of different metal products through the action of chemical potions, such as sand patterns, stripes, images, wood patterns, leather patterns and silk patterns. Different technical processes produce different texture styles.

Polishing
Injection mold polishing has two purposes; one is to increase the smoothness of the mold, so that the surface of the product from the mold is smooth, beautiful and beautiful, and the other is to make the mold easy to demold, so that the plastic will not be stuck on the mold and cannot be taken off.

Sandblasting
Sandblasting is to shoot quartz sand to the surface of the mold through an air gun with a certain pressure, thereby forming a layer of frosted surface on the surface of the plastic mold design. When a plastic mold injects a product, it will form a matte effect on the surface of the product. Generally, sandblasting is divided into two types: fine sand and coarse sand. For sandblasting, the surface of the plastic part is easy to wear off.

Within this companion, you ’ll see some charted comparisons to traditional manufacturing styles that are intended to help position set AM material prospects for certain mechanical or physical parcels.

Generally, one or two materials used in injection moulding distinguish an cumulative material from all others. Feting that a many parcels will separate one material from the others, the recommended approach for opting a material for 3D printing is to first define what mechanical or physical parcels are crucial and identify critical- to- quality features. Also review the material and manufacturing options to find a fit grounded on your timeline and end- use thing.

What Plastic Is Used In Injection Moulding?
Opting a suitable material for injection moulded corridor is one of the most important aspects of any engineering product design. It's vital to consider the materials used in injection moulding selection at an early stage of product design as it impacts both part functionality and drivingcost. Plastic injection molding materials is important for producing plastic factors. The process requires an injection moulding machine, mould, and raw injection material. The injection moulding machine melts the plastic, which cools inside the mould to take the shape of the finished product.The consumption of plastics used in injection moulding has increased unprecedentedly in recent times due to the global demand for consumer products.

This demand has driven companies to find new and advanced polymers to repel any operation and terrain, performing in thousands of plastics and further than 45 polymerfamilies.According to the mat web database, there are over 70000 Thermoplastics and 18000 Thermosets available to choose from, pressing the challenges faced by engineering product contrivers.Narrowing down this vast selection of common injection molded plastics is an inviting task, so choosing a starting point is essential.

How to Determine the Types Of Plastic Used In Injection Molding?

Over Molding
One category of injection molding that integrate different materials, like rubber or silicone, into existing plastic parts, such as the soft elastomer material on the handle of a toothbrush.

Custom Injection Molding
When considering custom injection molding, it's of great importance to assess the complexity level of your project and let that dictate the customization level you need not only from the injection mold toolings themselves, but from front-to-back in working with molders.

Custom injection moulding depends on multiple scientific methods, analytical tools and injection moulding process technology in order to meet the precision and performance requirements for complex plastic components and applications. Although faster time to market is a definite consideration for custom injection molding projects, it isn't pursued at the cost of part design, injection moulding material selection, mold design and injection moulding process control. In order to achieve product design and end-use goal accurately, custom injection molders will use these key product development stages to inform choices about the appropriate injection moulding process step by step such as scientific molding, insert molding, multi-shot molding, overmolding, etc.

Custom Injection Molding

What Is Injection Moulding Used For?
Injection moulding application: Injection molding involves injecting hot, molten plastic material into a mold, which is then cooled and solidified to form the product. Injection moulding method is suitable for the mass production of complex products, especially in the field of plastic processing that occupies a large proportion.

Injection Molding Process Steps
Step 1: The tool closes and resin pellets are fed from a hopper into the barrel, which signifies the start of the injection moulding process steps.

Step 2: The screw rotates to auger the pellets forward toward the tool and resulting friction plus barrel heaters make pellets melt. The screw is pushed forward and injects the material at the force and speed necessary to properly fill the tool cavity.

Step 3: After the tool cavity is filled, the resin must be allowed to cool.

Step 4: When the injection moulding plastic part is cooling within the tool, the screw retracts and reloads with melt in order to prepare for the next injection.

Step 5: As long as the molded material reaches its ideal ejection temperature, the tool opens and the part is pushed out by the forward motion of the ejector rod and pins.

How to Produce a Good Plastic Turnover Box Mold?(2024年04月16日)

FOW1 — 2024-04-10T18:48:24+0900

https://www.key-plast.com/how-to-produce-a-good-plastic-turnover-box-mold.html

How to Produce a Good Plastic Turnover Box Mold?
Ⅰ. Types of turnover boxes

The turnover box is mainly used to transport various products, so it is also called the logistics box.

According to the different products to be transported, the turnover boxes mainly include the following categories: fruit turnover boxes, fish turnover boxes, industrial product turnover boxes, bottle turnover boxes, bread turnover boxes, etc.,

The two shot molding design guide of turnover boxes for different purposes needs to consider details such as shape design, superposition effect, load-bearing strength and production cost.

Below are some crates we made for reference.

Ⅱ. Focus on the details of the turnover box mold design

1) Design of cooling water circuit

The cooling of the turnover box mould is very important. Reasonable cooling can reduce the deformation of the product and shorten the injection molding cycle.

The size of the diameter of the waterway and the uniform distance of the arrangement need to be precise.

The diameter of the water channel is too small and the cooling is not timely, resulting in excessive mold temperature and resulting in deformation of the product, thereby increasing the production cycle of the product and reducing the production efficiency.

2) The slider core pulling and ejecting system of the turnover box mold

1. Slide core pulling

Most of the structure of the turnover box mold are fixed mold four-slide core pulling, this injection mold design engineering can make the surrounding of the turnover box smoothly draw out without scratching the surface of the product, and can also control the size of the mold, thereby reducing the cost of the mold.

2. Ejection system

The turnover box mold is usually ejected by the top plate. According to the actual situation, the design of the ejector system should be as simple as possible to reduce the probability of failure.

3) Gate design

For the gate design of the turnover box mold, we can choose either hot runner or cold runner.

Cold runners are recommended if return material will be added to the plastic material. The large gate is placed in the center of the bottom of the turnover box to avoid gate blockage.

If the turnover box is produced with new injection molding materials, it is recommended to choose multiple hot runners, which can not only reduce the excess runner waste, but also reduce the process of shearing the runner gate.

For the number of points of the hot runner, it is generally 2, 4, 6 or more points into the gate, which is finally selected according to the structural design and weight of the product.

3. Selection of mold steel

The steel of the turnover box mold is generally P20, 718, and 2738, which are more cost-effective.

The steel used for different mold parts of the turnover box mold is also different, and the steel needs to be selected according to the cost budget of the mold.

4. The requirements of processing equipment

The processing accuracy of the turnover box mold is not low, especially in the processing of the core, the cavity, the four-slider and the stripper plate, which requires good equipment processing to make the assembly easier and avoid flash and scratches.

5. The production experience of turnover box mold

As a professional plastic injection molding factory in china, Keyplast has made hundreds of turnover box molds. Keyplast has very sufficient experience in product design advice, mold design review, mold processing control, and comparison and inspection between samples and designs.

Below are some of the crate moulds we made by Keyplast.

Five Methods Control the Color Difference of Injection Molding Products(2024年04月14日)

FOW1 — 2024-04-10T18:47:27+0900

https://www.key-plast.com/five-methods-to-control-the-color-difference-of-injection-molding-products.html

Five Methods Control the Color Difference of Injection Molding Products
Color difference of plastic products is a common defect in injection molding. There are numerous factors that affect color difference, such as raw resin, masterbatch, mixing of color masterbatch and raw materials, injection molding process, injection molding machine, etc. Injection moulding processing manufacturers generally control the color difference from the following five aspects in the actual production process.

1. Eliminate the influence of injection moulding and mould factors

It is necessary to choose an injection molding machine with the same capacity as the injection molding products. If the injection molding machine has problems such as material dead ends, it is best to replace the equipment. The chromatic aberration caused by the mold gating system, exhaust groove, etc., it can be solved by the maintenance of the corresponding part of the plastic mold by injection moulding supplies suppliers. The problem of injection molding machines and mold must be solved first before production can be organized to reduce the complexity of the problem.

2. Eliminate the influence of raw resin and color masterbatch on injection molding products

Controlling injection moulding raw material list is the key to completely solving chromatic aberration. Therefore, especially in the production of light-colored products, the obvious influence of the thermal stability of the raw resin on the color fluctuation of injection molding products cannot be ignored. Given that most injection molding manufacturers do not produce plastic masterbatches or color masterbatches themselves, the focus can therefore be placed on production management and raw material inspection.

That is to strengthen the inspection of raw material storage. In production, the same product should be produced by the same manufacturer, the same brand masterbatch and color masterbatch as much as possible. For the color masterbatch, we need to conduct random inspection and test color before mass production. It is not only necessary to proofread with the last time, but also to be compared in this time. If the color difference is not large, it can be considered qualified. Just like the batch color masterbatch has a slight color difference, it can be The color masterbatch is re-mixed before use to reduce the color difference caused by the uneven mixing of the color masterbatch itself. At the same time, we also need to focus on testing the thermal stability of the raw resin and color masterbatch. For those with poor thermal stability, we recommend that the manufacturer replace them.

3. Reduce the influence of barrel temperature on the color difference of injection molding products

In production, injection moulding supplies are often encountered that a heating ring is damaged and failed, or the heating control part is out of control and the temperature of the barrel changes drastically, resulting in chromatic aberration. The color difference caused by such reasons is easy to determine. Generally, the color difference caused by the failure of the heating ring will be accompanied by uneven plasticization, and the uncontrolled long burning of the heating control part is often accompanied by product gas spots, severe discoloration, and even coking. Therefore, it is necessary to check the heating part frequently in production and replace and repair it in time when it is found that the heating part is damaged or out of control, so as to reduce the probability of such chromatic aberration.

4. Reduce the influence of automotive plastic injection molding injection molding process adjustment

When it is not necessary to adjust the injection process parameters due to non-chromatic aberration, the injection temperature, back pressure, injection cycle and the amount of color masterbatch added should not be changed as much as possible. At the same time, it is necessary to observe the influence of process parameter changes on the color. If the color difference of injection molding products is found, it should be adjusted in time. Avoid using high injection speed, high back pressure, and other injection molding processes that cause strong shearing effects as much as possible to prevent color difference caused by local overheating or thermal decomposition. Strictly control the temperature of each heating section of the barrel, especially the nozzle and the heating part close to the nozzle.

5. Master the influence of barrel temperature and color masterbatch on the color change of injection molding products

Before adjusting the color difference, it is also necessary to know the trend of the product color changing with temperature and color masterbatch. Different color masterbatches change with the production temperature or color masterbatch amount, and the injection molding color change rules of automotive plastic injection molding products are different. The change rule can be determined through the color test process. It is impossible to quickly adjust the color difference unless the color change law of the masterbatch is known.

What is the Difference Between Overmolding and Insert Molding?(2024年)

FOW1 — 2024-01-26T11:19:40+0900

https://www.key-plast.com/what-is-the-difference-between-overmolding-and-insert-molding.html

What Is the Difference Between Insert Molding and Overmolding?
Plastic injection molding is one of the most widely used processes for manufacturing high-quality and extremely precise parts. The process is known for its multiple advantages. Consequently, a wide range of industries have adopted this part manufacturing method. There are many types of injection molding technologies currently in use, depending on the parts to be produced. Among the many types, overmolding and insert molding are the two most common injection molding technologies.

1. Overmolding

As the name implies, overmolding is a process of molding one material on another. The first component is made in an injection mold and then placed in the second mold, where overmolding material is added. This technology combines a variety of plastics to achieve practical or aesthetic purposes. For example, people may use plastics of different hardness to mold soft plastics over hard plastics to make the parts easier to grasp. The use of multiple colors of plastic in overmolding parts can also distinguish the products from those of other brands. Overmolding is often used on the handles of tools such as screwdrivers, electric drills, or toothbrushes.

The advantages of overmolding injection molding are:

(1) Improve material flexibility

(2) Long service life

(3) Enhance security

2. Insert molding

Insert molding is a subset of plastic injection moulding china technology, similar to overmolding. Before the actual injection molding, the metal part is put into the mold cavity, and the insert is accurately positioned in the mold by manual operation or mechanical arm. Then the mold is closed and the plastic is molded on the insert to form a part. Most of the finished parts produced by this method are a combination of thermoplastics and metal parts, which are often used in aerospace, automotive and medical fields.

The advantages of insert injection molding are:

(1) Reduce assembly and labor costs

(2) Reduce the weight of parts

(3) Shorten assembly time

The above is the insert molding vs overmolding difference. Both have their own advantages and applications. The corresponding technology can be selected according to the type of parts to be manufactured.

Types Of Plastic Injection Mold Polishing(2024年)

FOW1 — 2024-01-26T11:19:06+0900

https://www.key-plast.com/types-of-plastic-injection-mold-polishing.html

Types Of Plastic Injection Mold Polishing
Introduction to the plastic injection mold polishing
These days, industrial products are developing in the direction of product high quality as well as product diversification, in this way mold quality is going to have an influence on product quality directly, so improving mold quality has become an important task. Injection mold polishing service is a technology that helps to obtain a smooth mold surface. It is very different from the surface treatment of other industries. It has higher standards for polishing process, smoothness, and geometric accuracy.

Types of plastic mould polishing tools
(1) Mechanical polishing

Mechanical polishing is a method of removing the protruding part on the workpiece surface by cutting or plastic deformation on the surface of the material to obtain a smooth surface. Whetstone, wool wheel, and sandpaper are usually used for manual operation; if the surface quality is high, the processes of ultra-precision grinding and polishing should be used. This technology can reach a surface roughness of Ra0.008 μm, which represents the best value for mold polishing.

(2) Chemical polishing

Chemical polishing refers to the plastic injection mold polishing process of immersing a material in a chemical medium to ensure the micro-protrusions on the surface of the material dissolve before the dents to obtain a smooth surface. The method can be used to polish workpieces with complex shapes and can polish multiple workpieces at the same time, with high efficiency. The surface roughness that can be obtained by chemical polishing is usually Ra 10 μm.

(3) Electrolytic polishing

The basic principle of electrolytic polishing is the same as that of chemical polishing, which is to selectively dissolve the surface of the material to form a smooth surface. Compared with chemical polishing, it can eliminate the influence of the cathode reaction to produce a more significant effect.

(4) Ultrasonic polishing

Ultrasonic polishing is a method that uses ultrasonic vibration of the tool part and uses abrasive suspension to polish brittle hard materials. The workpiece is immersed in the abrasive suspension, and then placed in an ultrasonic field together with the suspension, and the surface of the workpiece is ground and polished by the action of ultrasonic waves. Ultrasonic machining has a small macroscopic force, so it will not cause the deformation of the workpiece.

(5) Fluid polishing

Fluid polishing relies on the flowing liquid and the abrasive particles it carries to erode the surface of the workpiece to achieve the purpose of polishing. Hydrodynamic grinding is driven by hydraulic pressure, the polymer in the medium flows at low pressure, and the abrasive particles are usually silicon carbide powder.

(6) Magnetic grinding and polishing

Magnetic grinding and polishing of plastic molding china refer to the use of magnetic abrasives to form a brush under the action of a magnetic field to grind the workpiece. The method has high processing efficiency, good quality, and easy control of processing conditions. The surface roughness obtained by this method can reach Ra0.1 μm.

As a china plastic injection manufacturer, we will do our best to meet all the needs of customers.

Two Shot Molding(2024年)

FOW1 — 2024-01-26T11:18:25+0900

https://www.key-plast.com/two-shot-molding/

Two Shot Molding Design Guide
Two shot molding, also called double shot moulding, dual shot injection molding, multi shot injection molding or 2k injection moulding is one category of injection molding using two different thermoplastic materials to produce injection molded parts in two colors or two components in the double injection molding process to produce 2 shot moulding in large quantities quickly, economically and efficiently. Multi multi injection molding has characteristics as below:

Two shot moulding , co-injection, two color injection molding and multi component injection molding are all variants of advanced molding techniques.
A combination of hard plastics and soft materials.

Contact us today to discuss your project and experience the excellence of KeyPlast's double shot molding capabilities.

Two Shot Molding Process
Two shot plastic injection moulding has two stages in the whole process.

Firstly one shot of materials is injected into a mold and cooled to form a solid part. Secondly, the mold opens and rotates 180 degrees and then closes. The second shot of materials is injected into the mold, through or around the first molded part. After sufficient cooling, the mold opens and the multi-resin molded part is ejected. 2 shot moulding has key factors as below:

Melting temperature for the materials
Wall temperature for the mold
Injection speed for the molded parts
Delay time between injections
Temperature of the components

Two Shot Injection Molding Design Guide
The mold used in two shot molding consists of different tool sets. In rotating platen settings, these two shot injection molding tools share the same core, but different cavities. The runner must be designed to close during its inactive forming step.

Wall thickness is an important two shot molding design consideration when designing parts for a number of reasons:

Due to the molding pressure from the second step, the substrate wall should be thick enough to withstand the force without collapsing.

Walls should not exceed traditional thickness guidelines to produce effects attributable to irregular cooling.

To ensure accurate and thorough flow of 2k molding material into all parts of the cavity, the wall thickness should not fall below a certain minimum value.

Ideally, materials should be injected in a certain order, taking into account the following factors:

The first shot should be the harder plastic of the two.

If transparent and opaque materials are used, inject transparent materials first.

Generally speaking, the material with higher temperature is injected first.

For mold frame and insert design:

Make sure the mold can be rotated 180 degrees.

Any insertion should be symmetric.

The push rod plate and thimble are stabilized by a return spring to prevent damage during mold rotation.

The cooling system of double shot molding must be able to function adequately on the first and second shots.

As a china plastic molding company, we will do our best to meet all the needs of customers.

Over Molding(2024年)

FOW1 — 2024-01-26T11:17:10+0900

https://www.key-plast.com/over-molding/

Over Molding
Over molding of keyplast is a special plastic molding process. Molding over molding injection molding is similar to the two-color molding or two-shot molding process. Over moulding can make the surface of the product full of softness and increase product functionality and added value.

With this technology, product functions can be increased, such as noise reduction, vibration reduction, waterproof, anti-collision and added value. Overmolds is widely used in mobile phone protective shells/mobile phone protective sleeves.

Overmolding Process
Plastic injection overmolding has a process in which a certain materials used in injection moulding is molded in a primary plastic mold, and the molded part is taken out and placed in a secondary molding mold to inject the same or another plastic material into overmolding process. Overmolding process has key factors as below:

1. The chemical or mechanical bonding strength between the polymers is not enough, and the material of single or multiple parts is not completely filled;

2. Flashing of burrs on single or multiple material parts.

3. The injection molding machine must maintain the consistency of injection molding.

Insert Molding VS Overmolding
Insert molding and overmolding custom injection moulding are very similar, but there are significant differences between the two processes. Injection overmolding is a two-step process in which two separately molded parts are combined to enhance product functionality. While insert injection molding is a slightly faster process because the two plastic materials are molded at the same time. Besides, over molding can not only give designers and engineers more creative freedom, but cost-savings of assembled parts as well. Whether you choose insert molding or over moulding, we understand the importance of creating a strong bond between components. We'll recommend the right innovative polymer solution, like thermoplastic polyurethane overmolding (TPU overmolding) to deliver the chemical adhesion you need.

Overmolding VS Two Shot Molding
01
Two-shot injection molding
Two-shot injection molding is also called two-color mold injection. 2 shot injection molding, also called 2k injection moulding, is to inject two plastic materials on the same injection molding machine in two moldings, but the product is only ejected once. The mold is usually completed by a set of molds and requires a special two-color Injection molding machine.

The same back mold, different front molds, high production efficiency, good product quality, suitable for mass production.

02
Over molding
Over molding, the two plastic materials are not necessarily injected on the same injection molding machine, but are molded in two parts; after the product is taken out from one set of molds, it is placed in another set of molds, inject molding. Therefore, this molding process is usually completed by two sets of molds, without the need for a special two-color injection molding machine.

Injection overmolding is to first take part of the product out of injection molding, and then put it into another injection molding machine for injection molding. The efficiency will be slower and the cost will be higher, so it is suitable for small batch production.

Why so many manufacturers like over molding?
Regarding this problem, we can learn one or two of the advantages of overmolding injection molding.

First, the product quality of over-molding can be improved. Injection overmolding can optimize the copolymerization of hard and soft materials to form strong molecular bonds. The result is a single part with production and feature advantages. It can be used for various product designs in injection moulding applications. The injection overmolding also allows the use of transparent plastics, colorful graphics, and fashionable finishes for molding, thereby improving your product functionality and market value.

Second, plastic injection overmolding can reduce the cost of production. Complete the entire production process in one injection molding machine, overmolding injection molding effectively reduces unit costs, reduces processing and secondary assembly, and reduces costs and waste associated with assembly defects, thereby shortening the molding cycle and improving work efficiency.

Furthermore, China injection mold supplier can also improve people's experience. Over the past 10 years, it has completely changed the aesthetic standards, design ideas, and functional requirements of consumer products. The use of plastic materials with different textures has improved the touch and function of products. Many of the common toothbrushes and mobile phone protective cases in our lives are products produced by using injection overmolding technology.

Processing Performance and Conditions of ABS Injection Molding(2024年)

FOW1 — 2024-01-26T11:14:55+0900

https://www.key-plast.com/processing-performance-and-conditions-of-abs-injection-molding.html

Ⅰ. ABS Injection Molding Processing Performance
(1) Because of the strong moisture absorption as well as high water content of ABS, the plastic parts that are made of ABS have low gloss and poor internal quality. As a result, ABS injection molding should be dried so that the water content is not more than 0.3%.

(2) ABS melt has obvious non-Newtonian properties. Increasing the molding pressure can significantly reduce the melt viscosity, and its viscosity will also decrease with the increase of temperature.

(3) ABS has a small molding shrinkage rate, and the shrinkage rate changes in the range of 0.3% to 0.8%, so the precision of plastic parts is high.

(4) ABS injection molding has good processing performance, and there are no special requirements for injection molding machines. Both general screw and plunger injection molding machines can be used, but multi-purpose screw injection molding machines have better product quality.

(5) In order to improve the quality, dimensional stability, surface gloss of plastic parts and eliminate residual internal stress when using screw injection mold tooling machine, it is more appropriate to control the injection volume at about 50% of the maximum injection volume.

(6) The viscosity of ABS melt is medium, better than PC and PVC, but worse than PS, so it is better to use straight-through nozzle.

(7) The main channel of the ABS mold is preferably conical, and the main channel should be short, generally about 50mm, and the longest should not exceed 100mm.

(8) The cross-sectional area of the runner must be large enough so that the molten material can fill the cavity before the runner solidifies and compact in the mold. The diameter of the section should generally be greater than 5mm, but not more than 10mm.

(9) The ejection force of the ejection mechanism of ABS should not be too large, otherwise the surface of the plastic part is prone to whitening.

(10) Although the shrinkage rate of ABS injection molding is small, it is easy to generate internal stress, so the plastic parts generally need to be heat treated, and the plastic parts can be treated in hot air at 70 ° C for 2 to 4 hours.

Ⅱ. Conditions for ABS injection molding

(1) Barrel temperature

ABS is an amorphous plastic with no obvious melting point, and the melt flow temperature is not too high. It has sufficient fluidity above 160 °C, but if the temperature is too high, it will not increase the fluidity. There are many varieties of ABS, and the barrel temperature of different varieties is different. The barrel temperature of general ABS is 180~230℃, the temperature of heat-resistant ABS is 190~240℃, and the temperature of flame retardant ABS is 170~220℃. The nozzle temperature is 20~30℃ lower than the barrel temperature.

(2) Mold temperature

The level of abs injection molding temperature has a great influence on the quality of plastic parts. During ABS injection molding, the mold temperature should be controlled within the allowable range. Generally, the mold temperature should be controlled at 50-70 °C.

(3) Injection pressure

The size of the injection pressure mainly depends on the structure and wall thickness of the plastic part. Usually, the injection pressure of general ABS is 50-70MPa, the injection pressure of heat-resistant ABS is 60-85MPa, and the injection pressure of flame-retardant ABS is 60-100MPa. If the flow resistance during filling is large, use a higher injection pressure. Conversely, use a lower injection pressure.

Do not use the finest whetstone, sandpaper, or abrasive polishing paste at the beginning of mold polishing, as you can't throw away the rough lines. The living surface polished in that way looks very shiny, but when you take a side view, the rough lines appear. Therefore, it is necessary to polish from coarse whetstone, sandpaper or abrasive polishing paste, then change to finer whetstone, sandpaper or abrasive polishing paste for polishing, and finally polish with the finest abrasive polishing paste. This seems to be cumbersome and there are many processes. In fact, it is not slow. One process after another, the rough processing lines in the front are polished off, and then the following injection molding process step is carried out without rework, and the plastic injection molding surface finish can meet the requirements with one step.

Textured Finish
