Automotive Stamping Die Industry Status and Development Prospects
Dies are processing tools that process raw materials and give raw materials a complete configuration and precise dimensions. They are mainly used to efficiently and mass-produce related parts and components in industrial products. With the development of modern industry, the application of molds has become more and more widespread. In automobiles, electronics, instrumentation, home appliances, aerospace, building materials, motors, and communications equipment, about 60%-80% of parts and components rely on Mold forming, so it is called "the mother of industry."
Mold is an important part of the equipment manufacturing industry. Its high degree of industrial linkage is one of the important guarantees for industrial upgrading and technological progress. It is estimated that the proportion of molds that can drive related industries is about 1:100, that is, mold development is 100 million yuan, which can drive related industries to 10 billion yuan..
The molds are widely used and have a wide variety of methods. According to the classification of mold forming processing technology, the mold can be divided into stamping molds, plastic molds, casting molds, and forging molds.
I. Overview of Automotive Stamping Die Industry
In the downstream industries of the molds, the automotive manufacturing molds are used in large quantities. In the developed countries of the automobile industry such as the United States, Germany, and Japan, the output value of the automotive mold industry accounts for more than 40% of the output value of the mold industry, and it is about 1/3 of that in China. Mold products serve the automotive industry. In general, an ordinary car needs more than 1,000 to 1,500 sets of stamping dies, which accounts for about 40% of the total value of all molds required for vehicle production.
Automotive stamping die is an important technology and equipment for automobile production. Its design and manufacturing time account for about two-thirds of the automobile development cycle, and it is one of the main constraints of automobile replacement. Automotive stamping dies are characterized by their large size, complex work profile, high technical standards, and are technology-intensive products. In the past, automobile stamping dies generally used single-step dies and composite dies. However, with the advancement of technology and improvement of equipment level, multi-position dies and progressive dies that can reduce costs and increase production efficiency were gradually applied to automotive stamping dies. In design and manufacturing, it becomes the development direction of automotive stamping die manufacturing technology.
