Stamping is applied to the mold by the press and on the plate, strip, pipe and profiles and other external forces, thus producing plastic deformation or separation, to obtain the desired shape and size of the workpiece (stamping) of forming methods. Stamping and forging belong to plastic processing (or pressure processing), collectively known as forging. Stamping billet mainly hot and cold rolled sheet and strip.
Cold stamping generally no longer by cutting, or only a small amount of cutting. Hot stamping accuracy and surface state less than cold stamping, but still better than castings, forgings, machining less.
