[0002] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. It is called a cold stamping die (commonly known as a cold stamping die). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the desired parts. The shape of a traditional stamping die is usually a die plate fixed to a lower pressure plate by bolts. When it can be replaced, the entire lower pressure plate needs to be disassembled before it can be replaced. Traditional dies require manual demolding, and the mold and model fit too closely and are difficult to demold.
