Basic knowledge of stamping parts

Cold stamping is a leading metal processing method. It is based on the plastic deformation of metals and uses molds and stamping equipment to process sheet metal in order to obtain the required parts shape and scale. Compared with cold stamping and cutting processing, it has a series of advantages such as high productivity, low processing cost, high data utilization rate, stable commodity scale accuracy, simple operation, and simple mechanization and automation, making it particularly suitable for many productions.

Because sheet metal parts are light in weight and have satisfactory strength and stiffness, they can be processed into parts of various shapes and sizes according to different uses. Therefore, cold stamping parts are widely used in modern cars, tractors, motors, electrical appliances, instruments, surfaces and various civilian light industrial commodities. In national defense, such as aircraft, missiles, bullets, artillery shells and other commodities, the share of parts produced and processed by cold stamping is also quite large. With the rapid development of cars and household appliances, many leading industrial countries have paid high attention to the development of cold stamping production. For example, the output of the mold industry in the United States, Japan and other countries has exceeded that of the machine tool industry. In 1982, the annual output of molds in the United States was 5.77 billion US dollars, and the machine tool was 5.50 billion US dollars. In 1982, the annual output of molds in Japan was 860 billion yen, while the machine tool only 784.20 billion yen. The share of cold die stamping in the mold industry is very large. The trend of cold stamping abroad can be seen in turn.
