China's powder metallurgy industry started in the early 1950s, basically synchronized with Japan, but in terms of its speed of development, it lags far behind Japan, and the gap is greater than that of North America and Europe. After more than half a century of entrepreneurial development, on the basis of independent and independent development, through technological transformation and technology introduction, it has developed into a new industrial system with complete product categories, certain production scale and scientific and technological level. Especially in the past 20 years, China's powder metallurgy machinery parts industry has undergone great changes; the equipment level has been greatly improved and improved, and some enterprises have formed the world's advanced CNC powder presses and advanced sintering furnaces, with modern molds. Manufacturing equipment and testing equipment, which greatly increase the efficiency of development and development, improve the resilience of the enterprise market and participate in international competitiveness. At present, it has been able to provide supporting equipment for the automotive, motorcycle, construction machinery, household appliances, electronics, electrical equipment, defense industry, power tools and other industrial industries.
The convergence of powder metallurgy products in China is unreasonable. Lack of high performance products. High-strength, high-density, high-precision powder metallurgy parts used in automobile engines, shock absorbers, and gearboxes, high-precision micro-small oil-impregnated bearings, and high-performance friction materials are not enough. Product performance is low and reliability is poor. At present, powder metallurgy iron-based structural parts produced in China generally have product quality and reliability due to weak product development capabilities due to many sources of raw materials and auxiliary materials, quality management, production and technology. And the ability to compete for radiation has yet to be enhanced. Product innovation and self-development capabilities are weak, unable to meet the rapidly developing automotive manufacturing, electronic technology, office equipment and new disciplines, developing communication, cutting tools, leisure fitness, biotechnology, home, office automation, material delivery and Supporting needs of other high-tech industries.
In order to meet the requirements of the car for environmental protection, energy saving, reducing manufacturing costs and improving performance, thousands of key powder metallurgy parts for automobile engines, transmissions, etc. have been developed, such as exhaust valve seats, connecting rods, ABS rings, and Gears, sprockets, automatic transmission parts, cams, etc. Powder metallurgy parts are now an important foundation for automotive and automotive components. Powder metallurgy technology has become one of the core technologies for improving and improving the quality of automobiles and auto parts manufacturing, developing new materials, new products, reducing production costs and enhancing competitiveness.China's powder metallurgy industry started in the early 1950s, basically synchronized with Japan, but in terms of its speed of development, it lags far behind Japan, and the gap is greater than that of North America and Europe.
