The punch is used in conjunction with the punch rod, punch nut and punch nut. Generally used for punching purposes in iron tower factories.

     At present, the precision of punches produced by domestic professional manufacturers can reach ±0.002mm, which is at the international leading level.

     In the cold stamping process, stamping dies process materials into parts. Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. It is relatively common in industrial production. Stamping dies are technological equipment for stamping production and are technology-intensive products. The quality, production efficiency and production cost of stamping parts are directly related to the precision and quality of mold design and mold parts.
