Characteristics:
 
(1) stamping parts is on the premise of material consumption is not big, created by the stamping, light weight, good stiffness, its parts and sheet metal after plastic deformation, metal internal organizational structure to improve, to improve strength of stamping parts.
(2) Stamping parts with high dimensional accuracy, with the module size uniformity, good interchangeability. Don't need to be further mechanical processing to meet the requirements of the general assembly and use.
(3) stamping parts in stamping process, due to the surface of the material are not destroyed, therefore, have good surface quality, smooth and beautiful appearance, for the surface paint, electroplating, phosphating and other surface treatment provides a convenient conditions.

Problems of stamping:
 
1. Punch as materials, the cause of the distortion in the progressive die, die-cutting stamping surrounding by the method of excess stock, to form the appearance of salt pieces.
2. To suppress stamping materials, twist method:
Reasonable mold design; Add crush function; Punch edge end builds a inclined plane or curved; Daily mold production, should pay attention to maintenance of convex and concave die cutting edge sharpness; Cutting clearance is not reasonable or uneven clearance is also produce stamping parts material, the reason of the distortion, need to be overcome
