Stamping is a cold stamping processing method, which uses the power of standard or special stamping equipment to punch the material (metal or non-metal) to cut, bend or shape it into the finished shape and size of the mold. Stamping processing can be roughly divided into several different processing types such as shearing, bending, forming and extension. The machine tool used for stamping is called a punch, and the mold uses is called a stamping mold. Stamping is usually carried out on cold metal plates.
