Stamping is a method of forming and processing workpieces (stamping parts) of required shape and size by applying external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation. Compared with castings and forgings, stamping parts have the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with ribs, ribs, undulations or flanges that are difficult to manufacture by other methods to increase their rigidity.
The stamping method can be used to obtain workpieces with complex shapes and difficult processing, such as thin shell parts. The dimensional accuracy of the stamping parts is guaranteed by the mold, so the dimensions are stable and the interchangeability is good.
