In recent years, my country's mold industry has achieved rapid improvement in manufacturing technology through technology introduction, digestion and absorption, and re-innovation. The specialized production capacity of mold companies has been greatly enhanced, the modern mold industry system has basically formed, and the industry has achieved rapid development. The manufacturing technology of mold products reaches or approaches the international level, the quality is more reliable, and the international competitiveness is significantly enhanced. my country's mold products occupy an increasingly important position in the international procurement pattern. Data show that in 2019, my country's mold export value reached 6.246 billion U.S. dollars, and my country's mold import value in 2019 was 1.939 billion U.S. dollars, a year-on-year decrease of 9.37%.

Among all mold types, plastic and rubber molds are the largest import and export varieties of molds in my country. Data show that in 2019, my country's plastic and rubber mold exports reached 3.967 billion U.S. dollars, accounting for more than 60% of the total mold imports and exports during the same period, reflecting the strong competitiveness of my country's auto mold and home appliance mold products in the world. The import value of plastic and rubber molds was US$870 million, accounting for more than 44.89% of the total mold imports, indicating that there is still a large import substitution space for plastic and rubber molds in my country.
(1) Gradually popularize and apply digital mold technology
Digital mold technology is gradually applied to mold design and manufacturing in my country. In recent years, strong domestic mold companies have begun to apply digital mold technology to mold development, design, manufacturing, and testing, which has improved the reliability of mold design, shortened the mold development cycle, and achieved good economic benefits. It is expected that digital mold technology will gradually become the mainstream technology of mold manufacturing and be adopted by more mold companies.
(2) Laser rapid prototyping technology applied to mold manufacturing
Compared with the traditional molding process, the laser rapid prototyping technology has the advantages of high raw material utilization rate (close to 100%), suitable for complex structures, easy integration and intelligence, and is an ideal molding process for molds. At present, laser forming processes such as LOM, selective laser sintering technology and SLS have been successfully applied to mold manufacturing. Laser rapid prototyping technology has broad application prospects in automobile mold manufacturing, and is one of the important development directions of mold molding technology.
(3) Management informationization and scientification
Informatization and scientific management is an important aspect of the development of automobile mold technology, which promotes mold companies to continuously develop in the direction of on-time manufacturing and lean production. With the advancement of modern management technology, many advanced information management tools, including enterprise resource management system ERP, manufacturing execution system MES, product life cycle management PLM and other advanced information management tools, are continuously being used in mold companies. Through process optimization, efficient use of resources and strengthening of execution, the mold production efficiency and corporate management efficiency are improved to make production more accurate and efficient.
