Metal stamping processing is by punching and stamping die on the plate, strip, pipe and profile, so as to produce plastic deformation or separation, so as to obtain the required shape and size of the workpiece (metal stamping) forming processing method.

Compared with castings and forgings, metal stamping parts are thin, even, light and strong.

Hardware stamping can improve the rigidity by producing workpieces with stiffeners, ribs, undulations or flanges that are difficult to manufacture by other methods.

Due to the use of precision stamping die, the workpiece precision up to micron level, and high repeatability, specifications consistent, can metal punching holes and pits, boss, etc.

Cold punching hardware stamping parts are no longer generally by cutting, or only a small amount of cutting processing.

The precision and surface condition of hot stamping parts are lower than that of cold stamping parts, but still better than castings and forgings.
