A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) in cold stamping. It is called a cold stamping die (commonly known as a cold stamping die). Existing stamping dies are suitable for processing single-hole, equal-wall-thickness aluminum plates. They lack supporting force for multi-hole, unequal-wall-thickness aluminum plates. Thin-walled areas are subject to large forces and are easily deformed. Multiple holes cannot be punched at the same time. Therefore, we designed a multi-hole, unequal-wall-thickness aluminum mold for automobile parts.
