How to Prevent Mold Damage? Aug 11, 2021

The reasonable structure design can ensure the service life of the mold, therefore it's the foundation for molds. Shunhao Machine and Mould Factory has lots of successful cases in melamine compression molds making. Since 2002 customers from 30 more countries recognize and have been maintaining long-term cooperation with Shunhao.

In order to make sure the mold working for a long service time, the molds making must obey the following 3 rules.

1. Good casting structure design

  • The casting must have a uniform thickness to reduce the thermal fatigue caused by the local heat concentration of the mold.
  • Except the thickness, the castings must have rounded corners to avoid stress caused by sharp corners on the mold.

2. Reasonable mold structure design

  • Maintain the thermal balance of the mold.
  • In order to ensure that it is not deformed under pressure, the mold should have sufficient rigidity and strength.
  • The purpose of casting the mold is to reduce the impact and erosion on the core.
  • The tolerance and surface roughness of each component should be selected correctly.

3. Standardize the heat treatment process

  • The correct heat treatment process can obtain the best mold performance, that is, strength, hardness, high temperature dimensional stability, thermal fatigue resistance and material cutting performance.
