The main factors affecting mold life.

1. The structure of the mold -effective mold structure helps to improve the load carrying capacity of the mold and reduce the mechanical load on the mold;

2. The material of the mold - should be selected according to the size of the production batch of the product parts;  The hardened mold will bring more shots and meet the high require for the mold treatment.

3. The quality of the mold machining  - the defects of the mold parts in machining, EDM, hardening and surface treatment will have a significant impact on the wear resistance and anti-seizure ability of the mold;

4 The mold working state when production - the accuracy and rigidity of the equipment used, the lubrication conditions, the pretreatment state of the material to be processed, the preheating of the mold and the cooling conditions all affect the life of the mold;


The design of the mold life is also an index paper that affects the cost of the mold. In the actual production process, we must balance these factors according to product parts and objective needs to obtain the best economic benefits and meet the needs of production.
