High-strength fasteners should not be developed in high-end line

Hits:Updated:2017-08-03 10:08:40【Print】

      Although China's fastener production accounts for a quarter of global production, but most of the low-strength, low-grade products, fasteners as the main mechanical products industry, the development of machinery industry, but also on the fastener products higher requirement. Ordinary standard fasteners have been oversupply, and high-grade fasteners (high temperature, shaped, titanium plastic composite, special performance and other fasteners) in short supply, but also rely on imports. Therefore, the National Machinery Bureau to "ordinary standard fasteners" as a restricted development products, "high-strength special-shaped fasteners" as the current development of products to encourage. High-strength fasteners with the national level of industrialization and technological progress, the use of gradually increased.
      China's fastener market has been greatly developed, the state in the introduction of technology, technological innovation, scientific research and development to give some support, but China's fastener technology compared with foreign levels, there is still a small gap, specifically in the : Low-end varieties, low level, the quality of instability, early failure rate is high, poor reliability. And in China's introduction of technology, foreign drawings and materials components can be provided to China, but in the heat treatment, foreign strict confidentiality, we can learn from a very limited. Therefore, China's future fastener industry development, we must establish the core competitiveness of enterprises and cultivate the industry's internal driving force, from the manufacturing power to the manufacturing power forward.
      With the nationwide infrastructure policy, construction machinery - loaders, excavators, rollers and other conservative will reach 6 million units, annual sales of about 50,000 units, according to estimates, the demand for high-strength fasteners about In the 20,000 to 30,000 tons. At the same time, China's national economic construction is entering a new stage of development, China's high-speed rail, aviation, highways, large-scale power generation equipment, large ships, large complete sets of equipment, represented by advanced manufacturing will also enter an important development direction.
      Road traffic: high-speed rail aerospace airport and other key state construction projects are tight for enterprises to provide high-end opportunities, Boeing plans to add 3400 aircraft in the future 20, the National Development and Reform Commission invested 800 billion yuan to build six cities in the rail transit, according to 36 plans to build urban rail transit project city planning, by 2020, urban rail transit operating mileage will reach 6560 km, track fastener demand of 55-70 billion. These large projects will greatly enhance the high-strength fasteners, titanium and other high-end fastener demand, remove the low-end label is not impossible.
