Difference Between SMC and BMC
Difference Between SMC and BMCSMC is a combination of long chopped glass strands, mineral fillers and liquid thermosetting resin in the form of a malleable sheet material. Processing of SMC of is typically done by compression or injection molding.
Sheet Molding Compound (SMC) is a compression molding compound often used for larger parts where higher mechanical strength is needed. SMC is a fiber reinforced thermoset material. Glass reinforcement is between 10% and 60%, and glass length is slightly longer than Bulk Molding Compound (BMC) - between 1/2-inch and 1-inch (25mm).

BMC is a combination of short chopped glass strands, mineral fillers and liquid thermosetting resin in the form of a bulk material. BMC is suitable for either compression or injection molding.
Bulk Molding Compound (BMC) is a thermoset plastic resin blend of various inert fillers, fiber reinforcement, catalysts, stabilizers, and pigments that form a viscous, 'puttylike' injection molding compound. Bulk Molding Compound (BMC) is highly filled and reinforced with short fibers. Glass reinforcement represents between 10% and 30%, with glass length typically between 1/32-inch and 1/2-inch (12.5mm).

SMC Moulding Process
The basic process of the compression molding process is to place a certain amount of the pre-treated molding material into a preheating compression mold, and apply a higher pressure to fill the mold cavity with the molding material. Under the predetermined temperature conditions, the molding material is gradually solidified in the cavity, and then the SMC product is taken out from the stamper, and the necessary auxiliary processing is performed to obtain the final product.

BMC Material & Injection Molding Processes
BMC is the initial abbreviation of English Bulk Molding Compound, and the Chinese name is a group molding compound. Pre-mixed into a paste by unsaturated polyester resin, low shrinkage/low profile additive, initiator, internal mold release agent, mineral filler, etc., and then added thickener, colorant, etc., with different lengths of glass fiber, in special Stirring in the kettle is carried out to carry out a thickening process, which finally forms a dough-like intermediate material which can be used for molding and injection molding.

The BMC injection molding process basically follows the same rules as the injection mold. However, SMC and BMC composite molds also have different characteristics from injection molds, such as flow path, exhaust, heating, cavity pressure and balance, parting structure, mold steel used and precision, shrinkage and injection molds. Differently, the BMC mold is molded at a high temperature, and the plastic mold is molded at a normal temperature. Waiwai Tree can offer high-quality bmc injection moulds at very competitive prices, contact us for more information!

Bulk Molding Compound Manufacturing/SMC Mould Manufacturing
SMC and BMC molds require heating rather than cooling systems. The temperature of the mold is usually between 130 and 160. It is very important to keep the temperature of the mold and the exhaust gas when designing the mold. The mold is easier to fill, the product is not easy to be deformed, and the surface is better. Commonly used heating systems are steam, oil and electric heating rods.

Vacuum assisted systems for BMC and SMC molds: Products with Class A surfaces are usually vacuum-assisted, and the internal cavity and vacuum insulation of the mold are very important. The mold must have a sensor and a vacuum system to measure the mold temperature and pressure vacuum. Production SMC and BMC molds must guarantee high quality, long life and economy. Aobang Technology Co., Ltd.'s years of experience in the production of SMC and BMC molds and proficiency in machine, mold, material and process can ensure the maximum benefit of customers.

What Is a BMC Mould?
BMC is the abbreviation of Bulk Molding Compounds. It is also cluster moulding plastics.

What is a BMC mould? What are the features and applications?

BMC is a kind of thermosetting plastic, which mixes various inert fillers, fiber reinforced materials, catalysts, stabilizers and pigments to form a kind of adhesive "putty" composite material for compression or injection moulding. It is usually made into grains, logs or strips by extrusion method in order to facilitate subsequent processing and moulding.

BMC has many unique characteristics, such as high hardness, light weight, corrosion resistance, ultraviolet resistance, good insulation, excellent thermal characteristics. These make BMC more satisfying than thermoplastics. At the same time, because many components can be moulded at the same time with these components, there is no need for post-processing, so it is more economical from the production point of view.

At present, BMC composite products have been used in automotive, energy, electrical appliances, catering services, household appliances, optical instrument components, industrial and building supplies and other areas.

Zhejiang Aobang Technology Co., Ltd. has developed many BMC die products, such as taillight hood, electrical box, watt-hour meter box, new energy battery cover, automobile bumper die, die for automobile wing plate, guide hood die and so on.

Principle Analysis of Over Moulding Technology for Injection Mold(2024年02月07日)

waiwaitree — 2024-02-05T14:54:39+0900

https://www.waiwaitree.com/principle-analysis-of-over-moulding-technology-for-injection-mold.html

In the past 10 years, Over Moulding technology has completely changed the aesthetic standards, design ideas and functional requirements of consumer goods. Medical device manufacturers also recognize the potential advantages of the technology and continue to expand its application in the medical field. Secondary injection moulding technology is famous for creating "soft surface". But it also has many other functions, such as ergonomic design, two-color appearance, brand identification and feature improvement. Using this technology, we can increase the functions of products (such as noise reduction, shock absorption, waterproofing, collision avoidance) and added value. Secondary injection, like co-injection, double injection and sandwich injection, belongs to multi-material injection technology. The basic idea of multi-material injection moulding is to combine two or more materials with different characteristics to improve product value. In this paper, the first kind of injection material is called base material or base material, and the second kind of injection material is called cover material.

In the over-moulding process, the covering material is injected into the upper, lower, surrounding or inner parts of the substrate to form a complete component. This process can be accomplished by multiple injection moulding or embedded injection moulding. The commonly used covering material is elastic resin.

Development System of BMC Rotor Mould(2024年02月05日)

waiwaitree — 2024-02-05T14:53:33+0900

https://www.waiwaitree.com/development-system-of-bmc-rotor-mould.html

At present, in the development process of BMC mold, the BMC material is thermosetting resin. In the process of mold heating and curing, because of the expansion performance of BMC material, the pressure in the mold cavity suddenly increases, which makes it difficult to demould the BMC products, and the products are difficult to separate from the mold. Especially some products with long straight surface can not separate from the mold, resulting in die scrap and product development failure.

The BMC Rotor Mold can successfully complete the production process. Compared with the existing technology, it has the following advantages: there is a long straight surface product in the BMC rotor moulding, so it can not be separated from the mold, and it can be used when it can not set a large demoulding slope on the product surface. In the process of mold locking, the lock insert is locked up and down through the lock surface, so that the insert will have a fully fitted balance state, and the fit between the insert and the middle sleeve plate will leave a large space for fit clearance, which effectively prevents the die expansion during the injection molding process. When opening the die, the lock surface is removed and the insert is peeled off from the product quickly, so that the ejection production process can be completed smoothly and the stability of the whole die can be further improved.

If you want to know more about bulk molding compound process, please visit our website.

The high-composite precision molds produced by Waiwai Tree have the characteristics of low energy consumption; our SMC and BMC molds have no waste, and there is no need to clear the inner cavity. Having only a small temperature difference, our SMC/BMC composites have stable mold temperature, good appearance, and high efficiency. Thus, they are now widely used in new energy vehicles, high-speed rail, and electric motors.

https://www.waiwaitree.com/bmc-smc-products/smc-bmc-antenna-reflector.html

SMC/BMC Antenna Reflector
High precision, high efficiency, and high gain

The most important job of using SMC for the manufacture of antennas is to fully exploit its features and achieve high precision in antenna design from product design and process. Under the condition that the shrinkage ratio of the material and the SMC molding shrinkage rate have been considered in the mold size design, the SMC antenna reflective surface has a smaller shape from the original design paraboloid after molding. That is, the accuracy of the SMC molded antenna is completely guaranteed by the accuracy of the mold. The rms value of the SMC antenna molded integral reflection surface is 0.25 mm, and the rms value of the single-piece reflection surface of the split antenna is less than 0.3 mm, and the rms value of the reflective surface after assembly is less than 0.6 mm.

Corrosion Resistance of SMC/BMC Reflector
Conventional antenna materials such as aluminum plates and steel plates are made of metal materials, not as good as SMC which as a non-metal dielectric composite material in terms of acid resistance, alkali, salt, and corrosion resistance. The Pikington laboratory in the United States used infrared to analyze the surface of SMC materials and found that its surface is covered by additives, resin, and very fine calcium acid filler. It has good acid resistance, water resistance and corrosion resistance. The antenna reflection made by this material is solved the disadvantage of the traditional metal material antenna is easy to corrode. In coastal areas, rainy, humid areas and areas with excessive acid rain, the anti-corrosion advantages of SMC molded antennas are particularly prominent. The SMC molded antenna samples were placed in 130 highly corrosive chemical environments at an ambient temperature of 50 ° C. The results showed that the test samples showed little or no change.

Long Life SMC/BMC Antenna Reflector
The average aluminum plate antenna is as small as 2-3 years in the coastal area, and more often 4-6 years, and it will generally be damaged by salt spray erosion and aging. The most obvious example is the cable TV (CATV) in Taiwan, which was built earlier than the mainland. It is estimated that there are nearly 1000 satellite TV receiving antennas on the island, all built in the mid-1980s, all of which were aluminum plate antennas, until the early 1990s. , that is, has begun to replace. The service life of SMC molded antennas is generally more than 15 years; PROMLIN's prototype SMC molded antennas in 1985 are still working normally, and they are subject to typhoons and heavy rain every year.

Strong Wind Resistance of SMC/BMC Antenna Reflector

Since the antenna reflection surface is designed during the molding process, multiple longitudinal and circumferential rib structures are designed. According to the structural strength calculation, the SMC antenna can withstand a wind load of 45 m/s, which shows its remarkable structural rigidity and strength.

Special Reflective Layer Technology of SMC/BMC Antenna Reflector

The reflective surface of the SMC antenna uses a metal aluminum mesh as a reflective layer of electromagnetic waves. The aluminum mesh in the finished antenna is evenly embedded under the surface SMC, which can reflect electromagnetic waves and insulate the atmosphere, and plays a good protective role.

Good consistency, no deformation, easy to transport and install
Because SMC antenna adopts membrane pressure technology under high temperature and high pressure. Its material properties and processing technology determine the unparalleled consistency of SMC antennas with other antennas. This not only ensures the accuracy and high gain of the antenna, but also is very easy to install and debug. SMC, commonly known as "glass reinforced plastic", has the characteristics of no deformation, which eliminates the adverse effects of antenna deformation on the satellite receiving system during transportation.

Difference Between SMC and BMC
Difference Between SMC and BMCSMC is a combination of long chopped glass strands, mineral fillers and liquid thermosetting resin in the form of a malleable sheet material. smc moulding process of is typically done by compression or injection molding.
Sheet Molding Compound (SMC) is a compression molding compound often used for larger parts where higher mechanical strength is needed. SMC is a fiber reinforced thermoset material. Glass reinforcement is between 10% and 60%, and glass length is slightly longer than Bulk Molding Compound (BMC) - between 1/2-inch and 1-inch (25mm).

Bulk Molding Compound (BMC) is a thermoset plastic resin blend of various inert fillers, fiber reinforcement, catalysts, stabilizers, and pigments that form a viscous, 'puttylike' injection molding compound. Bulk Molding Compound (BMC) is highly filled and reinforced with short fibers. Glass reinforcement represents between 10% and 30%, with glass length typically between 1/32-inch and 1/2-inch (12.5mm).
SMC Material & Compression Molding Processes
SMC Material & Compression Molding ProcessesThe basic process of the compression molding process is to place a certain amount of the pre-treated molding material into a preheating compression mold, and apply a higher pressure to fill the mold cavity with the molding material. Under the predetermined temperature conditions, the molding material is gradually solidified in the cavity, and then the SMC product is taken out from the stamper, and the necessary auxiliary processing is performed to obtain the final product.

The pressing process of the composite molded product is a process of solidifying into a product in a cavity after the binder is loaded or heated under the condition that the curing agent is present or heated. Like smc plastic molding, smc injection molding temperature, molding pressure and mold exhaust, temperature balance, and mold structure all affect the quality of SMC products. It is necessary to determine the best solution under the consideration of various influencing factors.
BMC Material & Injection Molding Processes
BMC Material & Injection Molding ProcessesBMC is the initial abbreviation of English Bulk Molding Compound, and the Chinese name is a group molding compound. Pre-mixed into a paste by unsaturated polyester resin, low shrinkage/low profile additive, initiator, internal mold release agent, mineral filler, etc., and then added thickener, colorant, etc., with different lengths of glass fiber, in special Stirring in the kettle is carried out to carry out a thickening process, which finally forms a dough-like intermediate material which can be used for molding and injection molding.

The BMC injection molding process basically follows the same rules as the injection mold. However, SMC and BMC molds also have different characteristics from injection molds, such as flow path, exhaust, heating, cavity pressure and balance, parting structure, mold steel used and precision, shrinkage and injection molds. Differently, the BMC mold is molded at a high temperature, and the plastic mold is molded at a normal temperature. Waiwai Tree can offer high-quality bmc injection moulds at very competitive prices, contact us for more information!
BMC/SMC Mould Manufacturing
SMC and BMC molds require heating rather than cooling systems. The temperature of the mold is usually between 130 and 160. It is very important to keep the temperature of the mold and the exhaust gas when designing the mold. The mold is easier to fill, the product is not easy to be deformed, and the surface is better.

In recent years, with the rise of all electric injection molding machine, there are some new trends in mold technology. One of the most striking changes is the application of servo motor in mold.

In the production of traditional screw cap, the process of die opening, oil pressure action and reaming is generally experienced. After replacing the traditional oil pressure system with servo motor, the servo motor rotates synchronously in the process of die opening, and the reaming is completed at the same time of die opening, which greatly shortens the forming period. This point has the incomparable attraction to the screw cap manufacturer.

For another example, the traditional core pulling action is generally completed by mechanical slanting guide post, which is generally core pulling while opening the mold. But in some cases, people want to pull the core after opening the mold completely. This exposes the disadvantage that the traditional oil pressure system can't control the time. The introduction of servo motor can precisely control the time of core pulling action, thus bringing greater production flexibility for manufacturers.

At present, the application of servo motor in the mold industry is quite common in foreign countries, but the mold industry in China is very rare. For the whole mold manufacturing cost, the use of servo motor will not significantly increase the cost, but it can bring more efficient and flexible production mode for the SMS injection molding and BMC injection molding industry.

Specification of Glass Fiber Content in SMC Moulding Process(2022年)

waiwaitree — 2022-01-13T15:59:56+0900

https://www.waiwaitree.com/bmc-smc-mould/

The SMC moulding process is the most widely used in the United States. It is mainly used for housings, chassis, bumpers, spoilers in the automotive industry, high-voltage switch cabinets in the electrical industry, building water tank boards, farmland irrigation, and construction accessories.

In the SMC moulding process, the glass fiber content can reach 30%, and the performance requirements of SMC are as follows:

1. Excellent clustering and low solubility, proper permeability. It requires excellent yarn bundling and low solubility. In this way, it can be ensured during the SMC moulding process that the resin paste with high viscosity can penetrate vertically through the thick chopped glass fiber accumulation layer. This requires that the insoluble content of the main film-forming agent of the sizing agent is greater than 90%, the yarn has no tendency to monofilament and is easy to shape.

2. The stiffness is high, preferably greater than 160 mm. This requires high hardness and strength of the sizing agent film, and high solid content of the sizing agent, sometimes up to 13%, to ensure that the yarn oil content LOU is above 1.5%.

3. Excellent cutting performance, good yarn rigidity, low static electricity, and low ribbon formation. Under the premise of ensuring the uniform force of each strand of yarn, each strand of yarn can be dispersed and arranged in parallel. This ensures that it is easy to disperse on the unit and is evenly dispersed after settlement. To further improve the cutting and bundling properties of the yarn, 0.2-1% polyurethane emulsion can also be added to the formulation.

During film formation, a macromolecular network structure is formed due to the action of the crosslinking agent, which improves the rigidity and strength of the film, and at the same time makes it insoluble in styrene. The compound coupling agent used in the formula is also to improve the stiffness of the yarn. When drying the SMC yarn precursor tube, the temperature should be high, generally up to 135°C, and the time should be more than 10 hours to ensure the full progress of the crosslinking reaction of the film-forming agent.

Details determine success or failure, It is believed that everyone must understand this truth. This is especially true in industrial production, and even more so for the production of SMC molds, otherwise, the slightest error will be greatly affected, and the entire product quality will be affected later. Let's briefly talk about the details that need to be paid attention to in the production of SMC molds, which are as follows:

1. The silicone rubber material is in a fluid state before use, with good fluidity and filling properties. After being formulated, a rubber elastomer is formed through a cross-linking reaction, which can have greater elastic deformation, and the water in the original mold has no effect on its cross-linking reaction. The cross-linked silicone rubber has good sealing performance and does not adhere to the original mold and FRP. Using it as the surface layer material of the SMC mold can not only produce the shape of the work with high quality but also ensure smooth demoulding.

2. The specific SMC mold making method is: apply the prepared silicone rubber to the original mold several times, the silicone rubber layer should be more than 1mm thick (note the details, not too thick).

3. After the silicone rubber is cross-linked, an FRP layer with a thickness of about 3mm is formed on the silicone rubber.

4. After the glass fiber reinforced plastic is cured, cut the overall mold along with the divided unit blocks, and pay attention to simultaneously cut the glass fiber reinforced plastic layer and the silicone rubber layer when cutting. The connecting ribs are made between the unit blocks, and a slot should be set at the connecting ribs to ensure that the unit block molds are combined into a whole through the connecting ribs.

5. After the above work is completed, demould the glass fiber reinforced plastic unit block, then remove the silicone rubber layer, and put the removed silicone rubber block back into the glass fiber reinforced plastic unit mold immediately.

Generally speaking, the main process of making the SMC mold is as follows: Dust removal from the original mold → silicone rubber preparation → silicone rubber layer production → glass fiber reinforced plastic layer production → mold segmentation → connection rib production → demolding and assembly mold. Every link needs to be paid attention to details to ensure the results of the entire SMC mold.

BMC/SMC -- High Strength Energy-Saving Building Materials(2022年)

waiwaitree — 2022-01-13T15:59:00+0900

https://www.waiwaitree.com/

Aviation polymer fireproof board (German abbreviated as GFK), is a new type of high-strength energy-saving panels made of fiber, flame-retardant resin, aluminum hydroxide, and other materials, produced by special ultraviolet photochemical reaction, and the surface of the mold is made by nano-processing technology. While the BMC/SMC antibacterial board has the characteristics of ordinary building board polyurethane board, it also has many characteristics that other metals and non-metal building materials do not have.

It is promoted as a new energy-saving material in Europe and is widely used in the construction industry, aerospace, wind power generation, new energy vehicles, medical equipment, and mining crawler transportation.

As a new type of high-strength and high-energy-saving building board, its main characteristics are as follows:

1. It can fully replace color steel tiles, polystyrene sandwich panels, polyurethane sandwich panels, and other steel plates saving a lot of steel and ore resources for the country, saving coal, electricity, and other energy for steelmaking.

2. Energy saving, heat insulation, and heat preservation performance: low thermal conductivity and less heat loss. Thermal conductivity refers to the heat transfer through an area of 1 square meter in 1 second for a material with a thickness of 1m and a temperature difference of 1 degree (K, °C) on both sides under stable heat transfer conditions. It is expressed by λ, the unit is watt/(meter·degree), w/(m·k), (GFK antibacterial board has a thermal conductivity of 0.073W (m·K), which is very low compared to metal materials. As we all know, metals are good conductors of heat. The thermal conductivity of aluminum is 237W/(m·K) and the thermal conductivity of iron is 80W/(m·K). We know that the lower the thermal conductivity, the less likely it is to lose heat. Because of the low thermal conductivity of the GFK antibacterial board, it has been tested that GFK antibacterial board can save 15%-30% of energy consumption when used in places requiring constant temperature, saving a lot of energy for the country.

3. Fire resistance: The SMC/BMC antibacterial board has been improved, and a large number of environmentally friendly flame retardants have been added on the premise of reducing organic components. The "National Fireproof Building Material Quality Supervision and Testing Center" has tested its combustion value-added rate index ≤50; The total heat value of combustion is ≤2.7; the smoke generation rate index is ≤10, and there is no burning drop, and the fire rating reaches A and A2.

4. Low combustion hazard: A large amount of aluminum hydroxide is added to the raw materials of the BMC/SMC antibacterial board. In the event of a large fire, the only combustion products are water, carbon dioxide, carbon monoxide, and dust, without nitrides, sulfides, halogens, heavy metals, and others. The poisonous gas is less toxic than pine burning, and there are no burning droplets.

5. Scratch resistance and super anti-fouling: The molding surface of the BMC/SMC antibacterial board is made by the mold using nano-processing technology. The surface is smooth and dense. There are no small honeycomb pinholes when magnified, and it is not easy to adhere to dust and liquid. The surface can be washed directly with water; the surface hardness is relatively high, the Barcol hardness can reach 70, and the surface is not easy to be scratched.

6. Anti-ultraviolet, after 1000H destructive anti-ultraviolet aging test (equivalent to 30 years of outdoor exposure), there is no cracking, bulging, powdering, and it can completely isolate ultraviolet rays.

7. Green and environmental protection: BMC/SMC antibacterial board raw materials are made of pure natural green materials, the molding temperature is 150 degrees, and the solidity degree is more than 99.9%, so there will be no volatilization of harmful substances. The samples were processed by the National Authorized Testing Center with reference to USEPA3052: 1996 digestion method and LCP was used for quantitative measurement. (LUSEPA6010C:2007) test, lead, cadmium, mercury, refer to USEPA3540:1996 processing sample. GC-MS measurement (LUSEPA8270D:2007) detects ten polybrominated biphenyls (PBBS). The ten polybrominated biphenyls (PBOES) are far higher than the national safety standards. For details, see the ROHS test report. GC-MS measurement (LUSEPA8270D:2007) detects ten polybrominated biphenyls (PBBS). The ten polybrominated biphenyls (PBOES) are far higher than the national safety standards. See the ROHS test report for details.

8. Zero formaldehyde: BMC/SMC antibacterial board products are tested by the national authorized testing center with reference to the "steam distillation method" to test the formaldehyde content of the product. Testing equipment is UV-YIS MQ=20mg/kg. The testing result is N.D (not contained).

9. Antibacterial and mildew proof: Imported silver ions are added to the raw materials of the BMC/SMC antibacterial board, and the BMC/SMC antibacterial board added with silver ions can effectively kill bacteria. The tested anti-bacterial and fungal rate is over 99.9%. Mildew is caused by humidity or dirt. After testing, the water absorption rate of the BMC/SMC board is only 0.013%, there will be no damp conditions, and its surface is smooth and dense and will not condense dirt. In order to achieve an effective anti-mildew effect, the national authorized testing center has carried out "Aspergillus niger ATTCC9642, rope green plum ATCC11797, Chaetomium globosum ATCC6205, Gliocladium viridis ATCC9645" various tests, and the anti-mold grade is level 1.

10. Lightweight and high strength: BMC/SMC antibacterial board has a density of 1.75 g/cm3, and a 2MM plate is about 4.2Kg per square. It has very good mechanical properties, high elasticity, high impact resistance, and has very good static resistance under large amplitude. The force value has a small linear thermal expansion coefficient. Through the DIN EN 356 test, the impact strength can reach 55 KJ/㎡, the bending strength is 65 Mpa, and the shrinkage rate is 0.03%.

11. Acid and alkali resistance: BMC/SMC antibacterial board has excellent chemical stability and is inert to acids, alkalis, salts, and oxidants. For example, there is no blistering, bulging, pulverization in concentrated phosphoric acid, hydrochloric acid, sulfuric acid, and their salt solutions at 100°C, and they are all stable, and they are widely used to replace metals and aluminum products on sailing ships.

12. The waste is easy to handle: instead of polystyrene and polyurethane sandwich panels, it will not produce white and other pollution caused by polystyrene, polyurethane sandwich panels after fires, and scrapping, reducing environmental pollution, and it is an environmentally friendly product. Thermal power stations are willing to recycle such waste as raw materials for power generation.

13. It has certain functions of blocking radar waves and anti-radar detection and has national defense application value.

Note: DIN series standards are German standards.

Development System of BMC Rotor Mould(2021年06月10日)

waiwaitree — 2021-06-10T11:10:53+0900

http://www.waiwaitree.com/development-system-of-bmc-rotor-mould.html
At present, in the development process of BMC mold, the BMC material is thermosetting resin. In the process of mold heating and curing, because of the expansion performance of BMC material, the pressure in the mold cavity suddenly increases, which makes it difficult to demould the BMC products, and the products are difficult to separate from the mold. Especially some products with long straight surface can not separate from the mold, resulting in die scrap and product development failure.

The BMC Rotor Mold can successfully complete the production process. Compared with the existing technology, it has the following advantages: there is a long straight surface product in the BMC mold, so it can not be separated from the mold, and it can be used when it can not set a large demoulding slope on the product surface. In the process of mold locking, the lock insert is locked up and down through the lock surface, so that the insert will have a fully fitted balance state, and the fit between the insert and the middle sleeve plate will leave a large space for fit clearance, which effectively prevents the die expansion during the injection molding process. When opening the die, the lock surface is removed and the insert is peeled off from the product quickly, so that the ejection production process can be completed smoothly and the stability of the whole die can be further improved.
