Standard Precision Mold Base Process

2022-02-17
If the heat treatment is improper during the Standard Precision Mold Base treatment, it will cause the mold cracking and the premature newspapers, especially the injection, no quenching, and then surface nitridation process, there will be surface cracks and cracks after the die casting thousands of modes.

Most Standard Precision Mold Base are medium and high carbon alloy steels. After quenching, partially cold cockhysite does not transform into martensite, continue for processing in the form of residual austenite, affecting processing performance. Stress in steel quenching is a result of tissue stress in the heat stress and phase change during the cooling process. The quenching stress is caused by deformation and cracking.
