The relationship between stamping parts and automobile stamping is very close.

  A large number of cold stamping processes have been adopted in the production of stamping parts in Dalian, which are suitable for the needs of multi-variety and mass production of automotive stamping parts industry. In medium and heavy trucks, most of the panels, such as body panels, and some load-bearing and supporting parts such as frame, carriage and other automotive parts are automotive stamping parts.

  The steel used for cold stamping is mainly steel plate and strip, accounting for 72.6% of the total steel consumption. The cold stamping material is closely related to the production of automotive stamping parts. The quality of materials not only determines the performance of products, but also directly affects the process design of automotive stamping parts, and affects the quality, cost, service life and production organization of products

  Therefore, the rational selection of materials is an important and complex task. When choosing materials, the metal materials with different mechanical properties are selected according to the stamping type and use characteristics of automobiles, so as to ensure the quality of products and save materials.
