Background technique

Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). 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.

Hardware refers to traditional hardware products, also known as "hardware", referring to five metals: gold, silver, copper, iron, and tin. After manual processing, it can be made into knives, swords and other works of art or metal devices.
