According to preliminary statistics, the Shanghai production car in stamping, plastic, die casting mold enterprises nearly 70, the annual output value of about 20 billion. Private enterprises, such as Hua Zhuang, 1000 edge Yi Feng, Huang Yan, Hani, a joint venture enterprise, such as Ogihara, Visteon, Koito, Taiwan-funded enterprises such as Lianheng, Wang Xu, Taiwan Lai Tong, etc., these enterprises big years of output value in 5 (more than) 00 million, billion yuan annual output value of nearly seven enterprises, individual enterprises, the annual growth rate of 100%.
Shanghai auto mold companies in the main hardware is rapidly narrowing the gap with international standards. In recent years. By lot to purchase state-of-the-art CNC equipment, including the triaxial to five-axis high-speed machine tools, large gantry machining centers and CNC milling machine, a state-of-the-art large-scale measurement and debugging equipment and multi-axis CNC laser cutting machine, etc., so that enterprises level and the ability to greatly improve the production of automotive panel die, even some enterprises has reached world advanced level, individual enterprises through industry collaboration. With one year can be completed at the same time of 4 to 5 models complete mold.
Because of the accumulation of popularization and application of CAD / CAE / CAM technology. Standardized structure, standard parts and typical structure of the use of its flexibility on this basis, the mold structure composite high degree of reasonable structure, such as the use of reliable be met. Some enterprises to establish a knowledge base tool library, the spindle head libraries, virtual processing to check for interference. Some companies also independently developed software to avoid undercutting CNC machine tools, precision machining, multi-axis machining, inclination processing methods. Some enterprises have achieved a transition to the vehicle parts from local parts, middle and low sedan mold,
Mold production capacity of high-end cars, and standard acceptance by Japan, Germany and other foreign companies. Die abroad of some of the high-end level of the gap is narrowing, all rely on imports of luxury cars in mold phenomenon is gradually changing.
