The advantage of stamping parts

Compared with the castings, forgings, pressing with a thin, uniform, the characteristics of light and strong. Stamping can make other methods are difficult to manufacture with rib stiffener, flanging, ups and downs, or artifacts, in order to improve its stiffness. Because use precision mould, workpiece precision can reach micron grade, and repeat precision is high, the specification is consistent, can punch a hole nest, convex sets, etc. Cold stamping generally no longer by machining, or only need a small amount of machining. Hot stamping precision and surface state is lower than the cold stamping parts, but it's still better than the castings, forgings, cutting processing capacity. Stamping process for mainly according to classification, can be divided into separation process and forming process two kinds big. Separation process is also called the blanking, and its purpose is to make from the sheet metal stamping parts along the contour line must be separated, and at the same time guarantee the quality requirements of the separation section.
