Fasteners are the main basic parts of the machinery industry. The development of the machinery industry also places higher demands on fastener products. At present, domestic ordinary standard fasteners have been oversupply, while high-grade fasteners (high temperature, special-shaped, titanium-plastic composite, special performance fasteners, etc.) are in short supply, and they must be imported. The State Bureau of Machinery classified "ordinary standard fasteners" as a restricted development product, and "high-strength special-shaped fasteners" as a product that is currently encouraged to develop. High-strength fasteners With the improvement of the industrialization level and technological progress of the country, the use of the fasteners has gradually increased.
China's fastener market has been greatly developed. The country has given certain support in the aspects of technology introduction, technological transformation, scientific research and development, but China's fastener technology still has a small gap compared with foreign standards. : Low-end varieties, low levels, unstable quality, high early failure rate, poor reliability. Moreover, in the technologies introduced in China, foreign drawings and material components can be provided to China, but in heat treatment, foreign countries are strictly confidential, we can learn from the very limited. Therefore, in the future development of China's fastener industry, it is necessary to establish the core competitiveness of enterprises and cultivate the internal driving force of the industry, moving from a manufacturing power to a manufacturing power.
