Precision stamping parts have an important position in industrial production, and after recent years of development, China's precision stamping parts industry has gradually become formal, and it is also showing its strength in the world market, but it is leading to a higher development direction There are still many difficulties and many problems, mainly in the following aspects.

Research on the manufacturing process of precision stamping parts The world has accumulated a lot of proprietary technology, especially the century-old factory, and the technology accumulation has reached a very high level. However, China has little accumulation of know-how in precision stamping parts, and there is still a long way to go.

The prominent problem that affects the life of precision stamping parts is the quality of materials and heat treatment. At present, due to the price of imported steel is too expensive, most of the precision stamping parts still use domestic steel when the output is not very large. The quality of domestic steel is not good, coupled with process control and instability of quality such as forging and heat treatment, resulting in a large difference in overall life, generally 1/3 of foreign countries.

The research on the finite element numerical simulation technology and the precision analysis of the precision stamping parts in foreign countries for the fine stamping process has reached a high level, and has been applied to the design check and design verification of precision stamping parts, and to optimize the structure. . Although some universities and research institutes in China have carried out basic research work in this area, there are still some gaps in the application research of these technologies.

In order to enhance the overall capability of China's precision stamping parts industry and accelerate the development of industry standards, it is particularly important to formulate national or industry standards for China's precision stamping parts in the context of comprehensive world standards and the actual development of our industry.
