【正文】 asure of a national product manufacturing quality, and it largely determines the product quality, efficiency and new product development capability.In stamping processing stamping die is a kind of special process equipment that materials (metallic and nonmetallic) are processed into parts (or semifinished products) , it is called cold stamping mould (known as cold extrusion die) .Stamping, at room temperature, which use the molds installed in the press to put pressure on the material to occur separation or plastic deformation, and thus to obtain a pressure processing methodof the necessary parts.
