Powder metallurgy industry in China started in the early 1950 s, basic synchronization with Japan, but in terms of its development speed, greatly behind Japan, compared with North America, Europe, the gap is bigger. Has experienced more than half a century of business development, on the basis of independent development, through the ">", "price", "ninth five-year technology transformation and technology transfer, product category is complete, has been formed development has a certain scale of production and scientific and technological level of the emerging industrial system. Especially the past twenty years, great changes have taken place in powder metallurgy mechanical parts industry in China; Equipment level had the very big improvement and improve, some enterprises has become the world's advanced CNC powder pressing machine and advanced sintering furnace, has a modern mold manufacturing equipment and testing equipment, this will greatly increase the development efficiency, greatly changed the enterprise image, enhance the enterprise market strain capacity and the participation international competition ability. Now for the automobile, motorcycle, engineering machinery, household appliances, electronics, electrical equipment, defense industry, power tools and other industrial sectors to provide supporting.

Look from the powder metallurgy production and total production in China, although after Japan, but from the product development capabilities, technical performance, product quality and manufacturing level and its competitive ability in the international market, and powder metallurgy world powers -- the United States, Japan, Europe, the gap is bigger. Main show is:

1. The assimilation products, the structure is not reasonable. Lack of high performance products. Automobile engine, shock absorber, transmission used in the high strength, high density, high precision powder metallurgy parts, high precision miniature oilless bearing, high-performance friction materials and other products can't meet the demand.

2. Product performance is low, poor reliability. At present, the production of powder metallurgy iron-based structure parts, generally speaking, due to the raw material powder and supplementary material source, quality management, production and technical problems, such as product quality is not stable enough, due to product development ability is weak, product performance and reliability, and competitive ability of radiation remains to be enhanced.

3. Product innovation and self development ability is weak, cannot satisfy the rapid development of automobile manufacturing, electronics, office equipment and communications in the development of new disciplines is, cutting tools, leisure fitness, biotechnology, family, office automation, material conveying and other high-tech industrial demand. At present, faw, no.2, saic company production car using powder metallurgy parts are mostly over imported auto parts.

In order to meet the car of environmental protection, energy saving, lower manufacturing costs and improve performance requirements, developed a car engine, transmission, etc. With thousands of key of powder metallurgy parts, such as, the exhaust valve seat, connecting rod, ABS ring, all kinds of gear, chain wheel, automatic transmission parts, CAM, etc. Powder metallurgy parts now is one of the important basic parts automotive manufacturing and auto parts. Powder metallurgy technology has become the automobile and automobile parts manufacturing improvement and improve the quality and development of new materials, new products, reduce production costs, enhance competition ability of one of the core technology.
