[0002] Automotive fasteners are parts used to fix various components or connecting parts on a car. Automotive fasteners are usually made by stamping during the preparation process. When performing the stamping operation, it is necessary to select a stamping die that matches the automotive fasteners. The raw material is placed between the upper die and the lower die and pressed into the required shape by a hydraulic cylinder or the like. When drilling holes in the stamped automotive fasteners, a punching device is required.
