   Automotive stamping parts, as the name suggests, are metal stamping parts that make up automotive components. In automotive stamping parts, some parts are directly made into automotive parts after stamping, while the other parts require welding, mechanical processing, or paint processing to become automotive parts after stamping. There are various types of automotive stamping parts, such as spring trays, spring seats, spring brackets, end covers, covers, compression valve covers, compression valve sleeves, oil seals, bottom covers, dust covers, impellers, oil cylinders, support ears, brackets, etc., all of which belong to automotive stamping parts.

   When selecting materials, the first step is to select metal materials with different mechanical properties based on the type of automotive stamping and usage characteristics, in order to achieve the goal of ensuring product quality and saving materials.

   The following principles should be followed when selecting materials for automotive stamping parts:

   The selected material should first meet the performance requirements of automotive components;

   The selected material should have good process performance;

   The selected materials should have good economic performance.

   A large number of cold stamping processes are used in the production of automotive stamping parts, which are suitable for the needs of the automotive stamping industry for multiple varieties and large-scale production. In medium and heavy duty vehicles, most of the covering parts such as body panels, as well as some load-bearing and supporting parts such as frames, carriages, and other automotive components are automotive stamping parts. The steel used for cold stamping mainly consists of steel plates and strips, accounting for 72.6% of the steel consumption of the entire vehicle. Cold stamping materials are closely related to the production of automotive stamping parts. The quality of materials not only determines the performance of the product, but also directly affects the process design of automotive stamping parts, affecting the quality, cost, service life, and production organization of the product. Therefore, selecting materials reasonably is an important and complex task.
