Custom metal stamping is one of the most common processes in custom metal processing. Today, let's talk about some common problems.

1. Mold problems

The molds used for stamping processing are generally special. Sometimes a complex part needs several sets of molds to be processed and formed. The precision of mold manufacturing is high and the technical requirements are high. It is a technology-intensive product. Therefore, only when the production batch of stamping parts is large, the advantages of stamping can be fully reflected, and better economic benefits can be obtained.

2. Security issues

There are also some problems and shortcomings in stamping. It is mainly manifested in the noise and vibration generated during the stamping process, and the operator's safety accidents occur from time to time. However, these problems are not entirely caused by the stamping process and die itself, but mainly due to the traditional stamping equipment and backward manual operation. With the progress of science and technology, especially the development of computer technology, and with the progress of electromechanical integration technology, these problems will be solved as soon as possible.

3. High strength steel stamping

Nowadays, high-strength steel and ultra-high-strength steel have well realized the lightweight of vehicles, improved the crash strength and safety performance of vehicles, and become an important development direction of vehicle steel. However, with the improvement of sheet strength, the traditional cold stamping process is prone to crack during the forming process, which can not meet the processing requirements of high-strength steel plate. Under the condition that the forming conditions cannot be met, the hot stamping forming technology of ultra-high strength steel plate is gradually studied internationally. This technology is a new technology that integrates forming, heat transfer and structure transformation. It mainly uses the characteristics of increased plasticity and reduced yield strength of sheet metal under high temperature austenite state to form through die.
