Our fastener industry needs to work hard to improve itself.

Time:2019-04-03

The screw is a tool that uses the physics and mathematical principles of the circular rotation of the object and the frictional force to gradually tighten the object. Screws are a general term for fasteners, everyday spoken language.

Our fasteners also need to continue to develop better.

The machinery industry is one of the main users of fasteners. Due to China's late understanding of the important position of mechanical basic parts in the machinery industry, long-term lack of investment has resulted in poor foundation, weak foundation and weak strength. In particular, with the improvement of the level of Chinese mainframes, the bottleneck of mechanical basic components behind the mainframe has become increasingly apparent. In recent years, although the state has given certain support in terms of technology introduction, technological transformation, scientific research and development, etc., compared with the current market demand and foreign level, there is still a big gap, which is manifested in: low product variety and low level. The quality is unstable, the early failure rate is high, and the reliability is poor.

As the main basic parts of the machinery industry, the development of the machinery industry also puts higher demands on fastener products. Luo Baihui believes that the current domestic standard fasteners have been oversupplied, and high-end fasteners (high temperature, special-shaped, titanium-plastic composite, special properties and other fasteners) are in short supply, but also rely on imports.

All domestic fastener manufacturers should look to the future, and the national key construction projects such as “High Speed ??Rail” “Aerospace” and “Airport” are providing opportunities for the high-end enterprises to go to the high-end. Boeing plans to add 3,400 aircraft in the next 20 plans, and the National Development and Reform Commission will invest 800 billion yuan to build rail transit in six cities. According to the plan of 36 urban rail transit projects, the new rail mileage will be increased by 2020. It reached 6,560 kilometers and the demand for rail fasteners reached 5-7 billion yuan. These large-scale projects will greatly enhance high-end fasteners such as high-strength fasteners and titanium alloys.

In the future, our fastener industry will have more and better development opportunities.
