Reasonable selection of materials for automotive stamping parts
A large number of cold stamping processes are used in the production of stamping parts in Kunshan, which is suitable for the diverse and large-scale production needs of the automotive stamping industry. 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 and carriages, are automotive stamped parts. The steel used for cold stamping is mainly steel plates and strips, accounting for 72.6% of the total steel consumption of the vehicle. The relationship between cold stamping materials and the production of automotive stamping parts is very close. 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.
We have found that the residual materials from the processing of metal stamping parts also have great value in utilization!
1. The surplus materials generated by shearing or stamping can be used to produce small parts, reducing the use of normal sheet metal and improving material utilization.
2. Sort and sell larger flat materials separately. For large pieces of valuable sheet metal that cannot be used by oneself, they can be classified and sold according to their types to increase the value of waste sales and increase profits.
3. Provide the remaining materials to the supporting manufacturers for material processing. For enterprises with supporting manufacturers, they can also provide available sheet materials to the supporting manufacturers and adopt the method of processing incoming materials to reduce procurement costs and increase profits.
