Mold is the basic process equipment in industrial production, a high-value-added, high-tech-intensive product, and an important field of high-tech industry. The level of its technical level has become an important indicator of a country's manufacturing level. With the continuous development of the national economy and industrial product technology, the demand for molds in all walks of life is increasing, and the technical requirements are getting higher and higher.

Although my country’s total annual mold production has ranked third in the world, among which stamping molds account for more than 40% of the total molds, the overall mold design and manufacturing level and standardization level are comparable to those of developed countries such as Germany, the United States, and Japan. There is still a considerable gap. As represented by large-scale cover die, my country has been able to produce some car cover die. The design and manufacture of car cover molds are difficult, and the quality and precision requirements are high, which represents the level of cover molds. The design and manufacturing methods and means have basically reached the international level, and the mold structure and function are also close to the international level. It has made a big step forward in the localization of car molds. However, in terms of manufacturing quality, precision, manufacturing cycle and cost, there is still a certain gap compared with foreign countries. The multi-station progressive die and multi-function die, which mark the advanced level of die technology, are the key types of precision molds developed in my country. In terms of manufacturing accuracy, service life, die structure and function, it is comparable to foreign multi-station progressive die and multi-function die. Compared with the mold, there is a certain gap.

The real development of stamping technology began with the industrial production of automobiles. At the beginning of the 20th century, the industrial production of Ford Motor in the United States greatly promoted the research and development of Chongshu. The research work is basically carried out in two aspects of sheet metal forming technology and formability. The key issues are fracture, wrinkling and springback, involving formability prediction, forming method innovation, and forming process analysis and control. But for most of the 20th century, the mastery of stamping technology was basically empirical. The analysis tool is a classic forming mechanics theory, and the problems that can be solved are very limited. Industrial developed countries attach great importance to the development of cold stamping production processes, such as the United States, Japan, and other die and mold industries that have exceeded the machine tool industry. The development trend of cold stamping can be seen from the steel composition of these countries. Stamping has become an important means and development direction of modern industrial production. As the pace of integration with international standards continues to accelerate, market competition is intensifying, and people have become more aware of product quality, cost and new product development capabilities. The importance of.
