Metal stamping refers to pushing a metal sheet into a stamping die, and using the pressure of a punch press to transmit it to the stamping die to complete the required metal stamping parts.

In the metal stamping industry, aluminum sheet is widely used due to its light weight, high strength, and corrosion resistance. However, springback often affects product precision. The following comprehensive explanation of the key points for aluminum sheet stamping springback control focuses on springback causes, control methods, and detailed parameters to help resolve production challenges and improve product quality.

Choosing the number of cavities (i.e., "number of cavities") is a key decision in metal stamping production, balancing production efficiency, cost control, and product quality. This decision requires a comprehensive assessment based on multiple factors, including the characteristics of the metal stamping part, production requirements, and stamping equipment conditions.

Excessively high equipment tonnage increases energy consumption, wastes equipment, and may damage molds due to excessive impact force. Excessively low tonnage, however, fails to meet part forming requirements, leading to problems such as incomplete stamping and cracking during drawing.

Metal stamping is widely used in the automotive, electronics, home appliance, and medical device industries. From automotive chassis components to precision mobile phone hardware, all rely on high-quality raw materials to achieve performance standards. However, common metal materials on the market vary significantly in price, strength, yield strength, and corrosion resistance. Improper selection can result in excessive product performance, increasing costs, or insufficient performance, leading to quality issues. Therefore, a comprehensive selection process combining multiple factors is essential to maximize cost-effectiveness.

The metal stretching process is widely used in a variety of fields, including automotive parts, electronic components, and hardware, and is a core process in the production of custom metal parts. However, in actual production, wrinkling during the stretching process plagues many factories. This problem not only compromises the parts' cosmetic precision and structural integrity, but can also lead to batch scrapping, significantly increasing production costs and time pressures. As a small custom metal parts manufacturer established in 1997 and dedicated to stamping and stretching for over two decades, we have accumulated extensive experience in addressing metal stretching wrinkling. We have compiled and shared key technical points to help our peers and customers efficiently address this production challenge.
