Variety of mechanical components based on specifications of the domestic variety, towers, for the aerospace,cast bronze weapons, machinery manufacturing, transportation, construction, mining, petrochemical, power, energy, electronic communications, textile and other equipment to provide support, and widely used in all aspects of social life.
After years of development, China's machinery manufacturing industry has formed the basis of categories of parts more complete, larger, has a competitive industrial system.
At present,bronze bushing China has mechanical parts based on more than 8,000 large-scale enterprises. In the 21st century, China Machine parts manufacturing for many years maintained an average annual growth rate of over 20%, 65% domestic market share, major equipment,dry bushing significantly increased the level of support has become a large export of electromechanical products, fasteners production in the world the first, plain bearing hydraulic components, gear sales, ranking second in the world market, sales of bearings and ranks third in the world die.
In recent years,sleeve bushing a substantial increase of the level of the equipment manufacturing industry, large sets of equipment have been able to basically meet the needs of national economic construction, but the basic components can not meet the matching requirements of the host, DU bushing has restricted the bottleneck in the development of major equipment. The performance of the main problems: First, weak scientific and technological innovation. bushing China Machine parts manufacturing of materials, lack of systematic research and application process, basic common technology R & D and investment in small and scattered experiments, weak technological base, less original technology and patented products, brass bushing causing early failure rate, short life poor reliability, with the world advanced level there is a big gap.
Ministry of Industry and basic mechanical parts made at this point the implementation of industrial revitalization program, Mould guide plate the development of the whole industry has a profound understanding. Proposed program based on 3 years parts and components to China's machinery manufacturing level has been markedly increased, independent innovation ability to achieve a larger increase,plasic bushing irrational industrial structure to improve the situation, gradually reversing the basic parts and components industry is seriously lagging behind the passive situation. Breakthroughs in key technology infrastructure components, products, technology reached the international advanced level in the early 21st century development of a number of key infrastructure components, to master a number of core technologies with independent intellectual property rights, supporting the ability of major infrastructure components and equipment to 70% more adjustment of the industrial and product structures, development of a number of high value-added products, foster a number of strong international competitiveness based professional components and brands to increase business transformation support, focus on strengthening the capacity building process and testing equipment, technical service platform to create a number of industries, improve the technical innovation system, consolidate the foundation of technological innovation. We believe in the "second Five-Year" period, the parts industry will big market capitalization companies, the entire sub-industry proposal "strong concern."
