machine@hongancn.comThe structural design and process of the mold are the foundation of the mold, and the sophisticated process and reasonable mold structure ensure the life of the mold to a certain extent. Shunhao Machine and Mould Factory has several years of experience in melamine tableware compression molds making and has been served for lots of customers home and abroad. For the prevention of mold damage, the molding making is better to follow the following three aspects.
1. Good casting structure design
The wall thickness of the castings should be as uniform as possible to avoid hot spots and reduce the thermal fatigue caused by the local heat concentration of the mold. The corners of the castings should have appropriate casting fillets to avoid stress caused by sharp corners on the mold.
2. Reasonable mold structure design
3. Standardize the heat treatment process
The metallographic structure of the material can be changed by heat treatment to ensure the necessary strength, hardness, dimensional stability at high temperature, thermal fatigue resistance and material cutting performance.
The correct heat treatment process can get the best mold performance, and the performance of the steel is controlled by the quenching temperature and time, cooling rate and tempering temperature.
