Fasteners are the main basic products in the machinery industry. The improvement of product technology and quality will help improve the level of the entire machinery industry; in turn, the development of the machinery industry will drive the development of mechanical fasteners, and the two are closely linked. But now a problem is becoming more and more prominent: for example, the level of China's mainframe is gradually improving, but mechanical fasteners have been lagging behind the mainframe... How to eliminate such a bottleneck phenomenon, and where to "seek" opportunities? This is a big problem facing China's mechanical fasteners.

weak foundation, weak

Compared with the international advanced level, the technical level of China's mechanical products is relatively backward, mainly in the reliability of product use, the life of the whole machine, the appearance quality and the level of information technology. These gaps are concentrated in the technical level of basic components.

The machinery industry is one of the most important users of fasteners. However, due to China's late understanding of the important position of mechanical basic parts in the machinery industry and a long-term lack of investment, the entire industry has a poor foundation, weak foundation and weak strength. Especially with the improvement of the level of the main engine in China, the bottleneck phenomenon that the mechanical basic parts lag behind the main engine 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., there is still a big gap compared with the current market demand and foreign levels. The specific manifestations are: less product variety and low level , the quality is unstable, the early failure rate is high, and the reliability is poor.

At present, there are thousands of Chinese machinery parts manufacturing enterprises, but most of the products have low technical content and cannot enter the mainstream market of key components. It is expected that in the future, my country's mechanical fastener enterprises will show cluster development. That is to bring together the mechanical fastener enterprises of similar and adjacent enterprises, take the lead of the local mechanical fastener association, and win the competitive advantage through continuous innovation. It is the characteristic private small and medium-sized enterprises that play an important role in the clustering of mechanical fastener products, and they rely on leading enterprises for OEM production. And in a special field both competition and cooperation, and gradually form an industrial chain.

Look to the "high end"

Fasteners are the main basic products in the machinery industry, and the development of the machinery industry also puts forward higher requirements for fastener products. At present, domestic ordinary standard fasteners have been in oversupply, while high-end fasteners (high-temperature, special-shaped, titanium-plastic composite, special performance and other fasteners) are in short supply and depend on imports. The State Machinery Bureau lists "ordinary standard fasteners" as restricted development products, and "high-strength special-shaped fasteners" as currently encouraged development products. With the improvement of the country's industrialization level and technological progress, the use of high-strength fasteners has gradually increased.

The machinery industry has urgent expectations for the development of fastener varieties and the improvement of performance. With the enlargement of major technical equipment and the limitation of parameters, it is necessary to develop more new varieties of fasteners with high temperature resistance, high pressure, radiation resistance, corrosion resistance and other performance requirements.
