Planning guidelines: It is necessary to plan the stamping parts to be satisfactory for product application and skill functions, and to facilitate assembly and repair. The planned stamping parts are necessary to improve the utilization of metal materials, reduce the types and standards of data, and reduce the cost of materials as much as possible. In the case of the promise, use low-cost data, as far as possible to make the parts free of scrap and less waste. The planned stamping parts need to be simple in shape and reasonable in structure, so as to simplify the structure of the mold and simplify the number of processes, that is, to complete the processing of the entire part with the least and simplest stamping process, reduce and then use other methods to process, and facilitate the stamping operation. It is convenient to arrange mechanization and automatic production to improve labor productivity. The planned stamping parts should make the standard precision grade and the appearance roughness grade lower as possible, and help the product exchange, reduce waste and ensure the quality of the product. The planned stamping parts should be used to process the existing equipment, process equipment and process as much as possible, and to facilitate the extension of the die life. The scale of the car wiper casing car wiper casing metal stamping parts use field Stamping of the car profession. Mainly to draw. In this part of China, we mainly gather in large factories such as car factories, tractor factories and aircraft manufacturers. Independent large-scale stamping and deep drawing factories are still rare. Stamping of professional parts such as cars. The first is punching and forming.
　　 Many of the companies are owned by standard parts factories and some independent stamping plants. Now there are many such small factories in the vicinity of some car factories or tractor factories. Electric equipment stamping factory. This kind of factory is a new industry, which is carried out with the development of electrical appliances. This part of the factory is mainly gathered in the south. A daily necessities stamping factory. Do some handicrafts, tableware, etc. These factories have also been carried out in recent years.
　　 Household appliance parts stamping factory. These factories were all launched after the development of household appliances in China, and most of them were scattered in home appliance companies. Special stamping enterprise. For example, the stamping of aviation parts is attributed to such enterprises, but these craft factories are also owned by some large factories.
