The die used for stamping is called a stamping die, abbreviated as a die. A die is a special tool for batch processing of materials (metal or non-metal) into the required punching parts. Dies are very important in stamping. Without a die that meets the requirements, it is difficult to carry out mass stamping production; without an advanced die, advanced stamping technology cannot be achieved. Stamping process and dies, stamping equipment and stamping materials constitute the three elements of stamping processing, and stamping parts can be obtained only when they are combined with each other.
