f nitrogen spring, etc. A substantial increase in the level of mold. With large, precision, plex, longlife mold as the representative of the high level of mold proportion to achieve 35% above, such as auto parts mold is capable of producing B level vehicle mold。 precision mold processing precision can reach microns。 precision progressive die can be in the range of 2020 ~ 2500 times / minute or more highspeed punch on the use of plastic mold。 accuracy can reach micron, adapted to the IT industry development needs。 a single set of weight of 120T, diameter of 4 meters of type mould has bee one of the most large mold etc.. In eight, for the mold manufacturing supporting service system is perfect with each passing day, China39。 s mold industry system basically plete. In nine, the mold industry layout has been improved. From the relatively developed Pearl River Delta, Yangtze River Delta region to the mainland and north extension, appeared a few new mold production relatively centralized area, with Beijing ferry look forward to long ( spring ), large ( even ), Cheng Yu ( southwest ), Wuhan ( Central China ), middle area of Anhui. But the development is not balanced, regional differences. Mold development to bee the new characteristics, mold Park (city, assemble etc) continue to emerge. The country has been pleted, beginning to take shape of the mold Park of about 15 or so. And a few places are planning the construction of Mold Park. Mold manufacturing in the manufacturing industry has been gradually known by people, also caused the attention of various government leader. The state adopted a policy support. Some local governments also from all aspects of the strong support. Compared with developed countries, China39。 s mold industry still has bigger difference, mainly: China is still in the global industrial chain division of labor in the lowend products, at the middle。 die too. In the anization of mold development, production, the developed countries generally use the concurrent engineering and project management, technology and management, strengthening of the workflow control, shortening the mold developing cycle, quality assurance。 in a professional production, developed more widespread. Specialized division of labor is to improve production efficiency, shorten the die design and manufacturing cycle and ensure the quality of products of the inevitable trend of development, it is helpful to highlight their core business, is conducive to the accumulation of product development, production management and service experience, to provide short term high quality, low cost of mold。 In the application of new and high technology, developed for a variety of high and new technology is used more and more widely, in more depth, level is higher also, including digital mould technology (3D design, design for manufacture (DF ), CAPP, CAM, CAT ... ) , forming process simulation (CAE) technology, high speed machining technology, automation technology, new material forming technology, surface treatment technology, novel ( multifunction) mold technology, information management technology and so on. The continuous development of high technology and is widely used to make the mold design and manufacturing level to an unprecedented height. In the new technical research and development innovation, including the innovation of forming method, forming quality improvement innovation, new material forming technology innovation, our。
