Stamping relies primarily on the interaction between the die and the press. The die consists of an upper and a lower section; the metal sheet is placed on the lower die, and the press drives the upper die downward, causing the sheet to undergo plastic deformation within the die cavity. The process encompasses steps such as blanking, punching, forming, and trimming, with the processing of complex-shaped copper components requiring gradual shaping through multiple stages.
The key to the stamping process lies in die precision; high-precision dies ensure that dimensional errors are kept within ±0.05 mm, meeting the requirements for precision assembly.
