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
