Aluminum alloy shell products are now everywhere in daily life, stamping is a relatively basic and common method in the processing of aluminum alloy shells. The combination of stamping and CNC machining can obtain aluminum shells for various products, while some products only require or exceed pure stamping. Most aluminum alloy shells are obtained by secondary processing of aluminum alloy plates. In mass production, aluminum alloy shells are mainly stamped. The aluminum alloy shell is particularly vulnerable to crushing and scratching during stamping production.

The complex structure aluminum alloy shell requires pure stamping, so the determination of the number of processes is very important. The number of processes has a certain impact on product dimensional accuracy, production efficiency, production cost, etc. What issues should be considered when determining the number of stamping procedures:

　　 (1) Order quantity of aluminum alloy shell: In large order production, each process should be combined as much as possible, using compound stamping or skip stamping to improve production efficiency and reduce production costs as much as possible. In the production of small and medium-sized orders, simple die stamping can be used, thereby reducing die manufacturing costs.

　　 (2) Dimensional accuracy requirements of aluminum shell; when the dimensional accuracy is very high, some auxiliary processes can be added appropriately to ensure product accuracy and reduce waste products.

　　 (3) The company's existing molding conditions and stamping equipment; overly complicated mold manufacturing and assembly is a huge test of the company's mold manufacturing conditions standards.

　　 (4) Stability of aluminum shell mold production; there are many factors that affect mold stability, such as mold material, mold assembly accuracy, lubrication conditions, etc. When determining the number of processes, some processes can be added appropriately to avoid the ultimate deformation during the stamping process, thereby effectively improving the stability of the stamping process.

　　 Aluminum alloy material is relatively soft, in order to prevent deformation and displacement of aluminum alloy during the stamping process. Accurate positioning must be set on the stamping die, and the positioning device needs to have a smooth surface without diamond corners. This can effectively reduce the disqualification caused by the stamping of the aluminum alloy shell.
