Stamping is a process of cutting, bending, or molding the material to desired shape and size of the finished product. It can be divided into different processing types such as shearing, bending, forming and drawing. By the action of simple stamping and the automatic/ semi-automatic feeding of materials, products of simple or even complex shapes can not only be produced automatically, but can also be consistent and interchangeable. From small parts such as washers and electronic parts to car covers, they can be molded by stamping. The commonly used raw material is stainless steel plate.
