Owing to low requirement of the roughness of button contact used by high voltage switch, it's hard to get to the precision requirement with common processing of punching die.

Therefore, the research of the fast manufacture technology method that develops the steel - based ramming mold is an important topic in the Material Forming and Process Engineering field.

Stamping is the main process for body, the design and technique of stamping die concern on body surface quality directly. This paper is emphasis on body die design and stamping process.
