BMC Communication Devices Plastic Injection Mold

Professional degree of the company:

The company has been engaged in mold making for 16 years, has a very rich experience in plastic precision injection mold making, proficient in the mold making from design to production, BMC plastic injection Mould is one of the molds that our company is good at making from the source of BMC Communication Devices Mould production quality control. The company has a strong and professional design team, which can produce high-quality moulds for customers.

injection molding process of BMC:

Material simple temperature and building temperature, during processing, BMC is required to maintain the fluidity of the material for a long time under the high temperature of the material cylinder. The temperature of the material cylinder is generally controlled in two sections, the temperature is lower near the hopper end, and the temperature close to the nozzle is higher.

BMC material has poor fluidity when the temperature is low, curing quickly at high temperature, and the combination of the BMC plastic mold is more complex. When the precision BMC plastic injection mould machine is in injection molding, it will increase the pressure of injection molding, so that the pressure of injection molding is about 80~160MPa.

The high speed of injection molding helps to improve the surface quality of the injection parts, shorten the curing cycle of BMC materials, but is not conducive to the exhaust, so the injection molding machine in the injection molding machine will appropriately reduce the injection molding speed to ensure the surface quality of the injection parts.

S136 steel advantages：

S136 is a kind of plastic die steel with corrosion resistance, which is the daily high-grade steel we say. Its corrosion resistance is very strong, and the machinability and hardenability are also very good. Moreover, its deformation rate is low, which can ensure good surface accuracy for BMC mobile case mould production. Even if it is used for a long time, it can maintain the previous high precision and is not prone to deformation and other problems.
