How do plastic molds prevent damage during injection molding? If we want to prevent damage, we have to improve our own strength. If we don’t have strength, why should customers choose us? Why don’t customers choose better ones?

Everyone says to shop around. If we want customers to stay, we have to improve our awareness of Plastic household mould/mold prevention, but this is not enough, we must do it to give customers a kind of trust. Today, Shenzhen Will Carter Mould Products Co., Ltd. will share with you: Measures to prevent damage to plastic molds during injection molding 1. Good casting structure design The casting wall thickness is as uniform as possible to avoid hot spots and reduce local heat in the mold Concentrated thermal fatigue.

The corners of the castings should have appropriate casting fillets to avoid stress caused by sharp corners on the mold.　　2. Reasonable plastic mold structure design　　1) Each component in the mold should have sufficient rigidity and strength to withstand pressure without deformation. The wall thickness of the mold must be sufficient to reduce deformation.　　 2) The gating system is designed to minimize the impact and erosion on the core.　　3) Correctly select the tolerance and surface roughness of each component.　　4) Maintain the thermal balance of the mold.　　3. Standard heat treatment process　　The metallographic structure of the material can be changed through heat treatment to maintain the necessary strength, hardness, dimensional stability at high temperature, thermal fatigue resistance and material cutting performance. The correct heat treatment process can get very good results, and the performance of the steel is controlled by the quenching temperature and time, cooling rate and tempering temperature.　　4. Die casting production process control　　 1) Temperature control: mold preheating temperature and working temperature; alloy pouring temperature, under the premise of maintaining good molding, use a lower pouring temperature.　　 2) Reasonable die-casting process: specific pressure, filling speed.　　3) Adjust the clamping force of the machine to make the mold evenly stressed. Pay attention to cleaning the residual debris on the surface of the mold, so as not to cause uneven force on the surface of the mold and cause deformation when the mold is closed.　　4) Strictly control alloy melting to reduce gas in molten metal.
