The efficiency of precision stamping and general stamping are generally more than twice as fast. The main reason is that the mold structure of fine blanking is different. The development cycle is twice as long as that of single punching, and the cost is more than three times higher.

1. Keep the surface of the convex and concave molds clean, and the blanks of the precision stamping parts need to be wiped clean before drawing, to avoid the unclean cleaning of the die working surface or the material surface and the inclusion of debris, which can damage the surface of the precision stamping parts and affect the quality.

What are the characteristics of aluminum alloy shell stamping forming technology?

⑴ Simple operation, easy to master, save time and effort, easy to achieve mechanization and automation;

Aluminum alloy stamping, because of its relatively low hardness compared to iron, is easy to break and is expensive. Therefore, when making molds from aluminum alloy materials, you should pay attention to the following issues:
