High-end fastener industry adjustment and localization

At present, China's vigorous infrastructure construction has brought a very big opportunity for the development of the fastener industry in China. How to reverse the disorder in the development of domestic fasteners is the main problem facing the industry.

“Fasteners are also called standard parts in the market, and they are the general term for a type of mechanical parts that are used when fastening two or more parts (or components) into a single unit. It is widely used in various applications. Machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools and molds, instruments, instruments and supplies, etc.” Luo Baihui, secretary-general of the International Model Association, said that with the development of China’s manufacturing industry, China's import and export volume one of the products, to achieve international standards, to promote China's fastener companies to the world, and promote the full participation of fastener companies in international cooperation and competition, are of great practical significance and strategic significance. The specific requirements for each specific fastener product's specifications, dimensions, tolerances, weights, performance, surface conditions, marking methods, and inspection, marking, and packaging items are specified separately in several national (industry) standards. For example, there are English, German and American systems.

The mechanical industry is one of the main users of fasteners. Because China has a relatively late understanding of the importance of mechanical parts in the machinery industry and lack of investment for a long time, the entire industry has a poor foundation, a weak foundation, and weak strength. In particular, with the increase in the level of China's host computer, bottlenecks that mechanical components lag behind the host are becoming increasingly apparent. In recent years, although the state has given certain support in the aspects of technology introduction, technological transformation, and scientific research and development, there is still a small gap compared with the current market demand and foreign standards. The specific manifestations are: low product varieties and low levels. , The quality is unstable, early failure rate is high, and reliability is poor.

Fasteners are the main basic parts of the machinery industry. The development of the machinery industry also places higher demands on fastener products. Luo Baihui believes that the current domestic standard fasteners have been oversupply, while high-end 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 restricted development products and "high-strength special-shaped fasteners" as currently encouraged development products. High-strength fasteners With the improvement of the industrialization level and technological progress of the country, the usage has gradually increased.

According to the understanding of the Jinmo Power Grid, during the 12th Five-Year Plan period, the number of construction machinery such as loaders, excavators, and road rollers will reach 6 million units, and the annual sales volume will be around 50,000 units. Based on this, it is estimated that high-strength fasteners will be required annually. About 20,000 to 30,000 tons. The basic parts represented by fasteners are not only the basic industries of China's equipment manufacturing industry, but also the important foundations for various fields of national economic construction. During the period of the 12th Five-Year Plan period, the industry must rely on new advantages such as technological progress, quality improvement, and product cost-effectiveness to achieve sustainable development while maintaining its partial cost advantage. It is estimated that by the end of 2015, the total output of the industry will reach 7.5 million to 8 million tons; under the overall situation of expanding exports, the export products will assume a fluctuating growth trend, and the average annual export growth rate is expected to be 8% to 10% during the 12th five-year period. By 2015, the total export volume of the industry will reach 30 billion yuan.

Under the huge market demand, how to ensure the orderly development of China's fastener industry will be the main problem facing it.

Therefore, China's development of relevant and stringent industry standards and improvement of industry chain access thresholds will be a strong support for the orderly development of the industry. In addition, at present, domestic fastener factories are limited to funds or other reasons, and more domestic and Taiwanese equipment are used to produce automotive fasteners. To ensure the large-scale production of high-end fastener products, the dimensional tolerance and form-position tolerance should be Increase the level of online monitoring tools and mold making. Eliminating non-conforming products in production to ensure the assembly quality of OEMs and OEMs.
