Professionals said that in recent years, the overall technical level of advanced precision stamping dies has improved rapidly, and its mold technology level, manufacturing precision, service life and manufacturing cycle have been significantly improved, and a considerable part of the high-quality molds The level has reached or is close to the international level of similar molds. For example, the company's air-conditioner fin-stage progressive die life can reach 500 million strokes, and its production scale and technological development are in a leading position in China. The developed 0.4mm pitch high-precision micro-connector progressive die has a manufacturing precision of 0.5, and the smallest punch 0.13mm directly grinds to the mirror surface, ensuring the finest part of the workpiece 0.17mm, bending accuracy 0.01mm and S-shaped High precision requirements such as bending. The company's motor core automatic lamination progressive die has a service life of more than 150 million punches. The technical level and lamination technology are close to the advanced level of similar foreign molds. Specialized large-scale iron chip progressive die with a diameter of 0.5m on a 400-ton high-speed punch, a large-scale precision die with a 0.88m square iron chip with 90 rotations, and a large precision die with a 1.2m diameter stator plate. Production level and capability are at the leading position in China.

Specialization has greatly improved the innovation ability of stamping die enterprises, and the technical level has developed in the direction of specialization, precision, excellence and strength. Many high-tech precision stamping dies and new technologies have emerged. It is reported that the air-conditioning fin stepping precision progressive die, which is urgently to be exhibited, can meet the rapid switching production of five types of sheet shapes, and has certain flexible production characteristics. The mold level is equivalent to the international advanced level. The lead frame of the exhibition is 37-station progressive die, one module and three columns. 48 inner and outer lead legs are punched in 1212mm, the minimum spacing is 0.12mm, and the flatness of the product is within 0.01mm. Its high-speed batch production performance and life expectancy are comparable to the international advanced level, and it has obtained structural innovation patents.

Compared with the international advanced level, the precision of many domestic precision stamping dies is getting smaller and smaller. The overall level of some precision stamping dies is equivalent to the international advanced level, not only completely replacing imported, but also a considerable part of the molds are exported to the United States. Industrial developed countries and regions such as Japan. The overall level of precision dies in China is close to the international advanced level, and a considerable number of precision dies are going abroad and participating in the world competition.
