How to avoid damage measures during plastic mold processing

December 11, 2023

How to prevent damage during plastic mold processing? To prevent damage, we need to improve our own strength. If we don't have the strength, why do customers choose us? Why don't customers choose better ones? They all say that in order to keep customers, we need to increase our awareness of prevention, but this is not enough. We must do it to give customers a kind of trust.
Preventive measures for damage during plastic mold processing:
1. Good casting structure design
The wall thickness of the casting should be as uniform as possible to avoid the generation of hot spots and reduce thermal fatigue caused by local heat concentration in the mold. There should be appropriate casting rounded corners at the corners of the casting 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 stiffness and strength to withstand pressure without deformation. The mold wall thickness needs to be sufficient to reduce deformation.
(2) The design of the pouring system should minimize the impact and erosion on the core as much as possible.
(3) Correctly select the tolerance fit and surface roughness of each component.
(4) Maintain thermal balance of the mold.
3. Standardize heat treatment process
Heat treatment can alter the metallographic structure of materials, maintaining necessary strength, hardness, dimensional stability at high temperatures, thermal fatigue resistance, and material cutting performance. The correct heat treatment process can achieve very good results, and the performance of steel is controlled by quenching temperature and time, cooling rate, and tempering temperature.
4. Control of die-casting production process
(1) Temperature control: preheating temperature and working temperature of the mold; The pouring temperature of the alloy should be lower while maintaining good molding.
(2) Reasonable die-casting process: specific pressure and filling speed.
(3) Adjust the locking force of the machine to evenly distribute the force on the mold. Pay attention to cleaning the residual fragments on the surface of the mold to avoid uneven force on the surface of the mold and deformation caused by these excess materials during mold closing.
(4) Strictly control alloy melting and reduce gas in the molten metal.
