The surface and intrinsic properties of stamping sheets have a great influence on the quality of the finished stamping product. The requirements for stamping materials are:

The die used in stamping processing generally has specificity, sometimes a complex part needs several sets of molds to be processed and formed, and the precision of mold manufacturing is high, the technical requirements are high, and it is a technology-intensive product.

In recent years, the level of stamping dies in China has been greatly improved. Large stamping dies have been able to produce a single set of molds weighing more than 50 tons.

In the case of producing dozens or hundreds of stamping parts per minute, the processes of feeding, stamping, discharging, and discharging waste are completed in a short period of time, and personal, equipment and quality accidents often occur.
