    The sheet metal stamping is one of machining process, It's also named pressing. Stamping is a forming method to use presses and dies to exert external forces on plates, strips, pipes and profiles, resulting in plastic deformation or separation, thus obtaining the desired shape and size of the work piece ( Metal stamping parts ). Stamping and forging belong to plastic processing(or pressure processing), collectively known as forging. The blanks are mainly hot-rolled and cold-rolled steel sheets and strips. Of the world's steel, 60 to 70% are plates, most of which are stamped into finished products.   Stamping processing is the production technology of product parts with certain shape, size and performance by means of the power of conventional or special stamping equipment, which makes the sheet material be directly deformed and deformed in the die. Sheet metal, die and equipment are the three elements of stamping. It is divided into hot stamping and cold stamping accor...
