In the mold downstream industry, the automobile manufacturing industry, mold used in the United States, Germany, Japan and other automobile manufacturing developed countries, automobile mold industry output value accounted for mold industry output value of more than 40% in China, about 1/3 Die products for the automotive industry services. General production of an ordinary car needs 1,000 to 1,500 sets of stamping dies, about the entire vehicle production required for all the mold output value of about 40%.
Automobile stamping die is an important process equipment for automobile production. Its design and manufacturing time accounts for about 2/3 of the automobile development cycle, which is one of the main factors restricting the automobile type change. Automotive stamping die with a large size, work-type complex, high technical standards, are technology-intensive products. In the past, automotive stamping dies used single-step and composite die structure design, and with the technological progress and equipment level, can reduce costs and improve production efficiency of multi-station mode, progressive die gradually applied to automotive stamping die Design and manufacture, a car stamping die manufacturing technology development.
