The easy pull cover die is a necessary technological equipment in the stamping production process, which plays a decisive role in improving product quality, prolonging product life and improving production efficiency.

However, it is difficult to meet the production requirements due to the loss of working size due to frequent wear and tear during the production process.

Therefore, it is very important to improve the durability of the die with easy pull cover.

Whether the design of easy pull cover mold is reasonable is the foundation of improving the durability of easy pull cover mold.

Therefore, effective measures should be taken to improve the durability of the easy pull cover die when designing the easy pull cover die. For example, the life of the easy pull cover die is often shown in punching the punch.
