In recent years, China's fastener industry has maintained a relatively rapid development, and the production, sales and nationalization level have been continuously improved. Fasteners are widely used in machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools and instrumentation and other fields, which are closely related to the development of equipment manufacturing industry. With the steady development of China's economy, the increasing demand of downstream fasteners industry and the strong support of national policies, the market scale of fasteners will continue to rise. In 2019, the overall market scale of fasteners in China will reach 138 billion yuan. High-end fasteners are mainly concentrated in aerospace, highspeed rail, wind power, nuclear power, automobiles and ships and other fields, which mostly belong to China's highend equipment manufacturing industry. In recent years, China's highend equipment manufacturing industry has developed rapidly, driving the steady development of highend fastener manufacturing industry. As early as 2013, China's highend equipment manufacturing industry, such as intelligent manufacturing, highspeed rail transit, marine engineering, accounted for more than 10% of the total output value of the equipment manufacturing industry. The highend equipment manufacturing industry is located in the highend of the value chain and the core link of the industrial chain. It is a strategic emerging industry that determines the overall competitiveness of the entire industrial chain. It is the embodiment of the core competitiveness of China's industry and has been strongly supported by the state. With the rapid development of aerospace, satellite and application, rail transit equipment, marine engineering equipment, nuclear power, wind power and automobile industries, the scale of highend fasteners market will continue to rise. In 2019, the scale of highend fasteners market in China will reach 59 billion yuan.

Compared with the advanced level of foreign countries, the technological level gap of fastener industry in China is still large, mainly reflected in the production equipment and raw materials. The small scale, backward production technology, poor equipment, slow technological innovation and poor surface treatment level of most fastener manufacturing enterprises in China have led to excessive production capacity of lowlevel products in the fastener industry, while the supply of highgrade fastener products is in short supply; in addition, the varieties, specifications and quality of steel used for fasteners in China are not yet complete. Fully meet the requirements of the fastener industry, resulting in the process that should be solved in the metallurgical industry has been transferred to fastener enterprises, currently only a few enterprises can rely on their own strong comprehensive strength to solve this problem.

Innovative fastener technology is the support of fastener development, and the trend of technology development determines the trend of industry development to a considerable extent. The core technology of fasteners is not only to speed up the development of special steel, but also to integrate the technical details and knowhow of manufacturing, testing and heat treatment of fasteners. In the future, China's fastener technology will gradually approach the advanced level of foreign countries in material selection, structural design, manufacturing technology, special technology, testing technology, surface coating technology and quality control. At the same time, the development of intelligent, integrated and supernormal manufacturing will also be the main trend of industry technology development.

1. Intelligent manufacturing is a new manufacturing mode of fasteners, which is the inevitable result of the development of automation, digitalization, networking and intellectualization of mechanical manufacturing. With the rising cost of labor, the continuous improvement of product quality requirements and the increasingly prominent diversity of demand, the demand for intelligent manufacturing of fasteners industry is becoming more and more urgent. Intelligent manufacturing will greatly improve the productivity and efficiency of fasteners, reduce the labor cost of enterprises, improve the working environment and labor intensity of workers, and improve product quality and reliability. Intelligent manufacturing includes the intellectualization of manufacturing process and equipment. Intelligent manufacturing process requires the development of various intelligent manufacturing systems, automation or intelligent production lines, and then the construction of digital workshop, digital factory and digital enterprise. Intelligent equipment requires enterprises to increase investment in R&D and technological innovation, improve the production capacity of production equipment and production matching. The key technical problems to be tackled in the future years are: automatic intelligent cold heading precision forming technology, cold heading machine technology and equipment for large size fasteners, precision forming technology for complex shape fasteners, automatic logistics equipment and automatic heat treatment production line.

2. Fusion manufacturing integration is the crossintegration of multidisciplines and the combination of multiprocesses, which is the trend of the new era. The integration of mechanical manufacturing technology, information technology and various hightech, machinery and materials, technology and culture will inject new vitality into the development of fasteners. The application of fusion technology will produce new fastening parts, manufacturing processes, processing equipment and systems, greatly enrich the product system of fasteners and expand the functions of products.

In addition, process composition and integrated innovation are particularly worth proposing in integrated manufacturing. Process compounding refers to the integration of various processes and processes into a single equipment, which greatly reduces process links and site occupancy, improves work efficiency, and thus improves product quality. Integrated innovation is an innovation activity that transforms all kinds of integration into scientific and technological achievements and productivity. It is an important way of integrated manufacturing and the main type of fastener technological innovation at present. It can be predicted that in the near future, there will be many innovative achievements in the integrated manufacturing of fasteners, which will directly promote the rapid development of fastener industry technology.

3. With the expansion of people's living space and the rapid development of technology, the requirements for fasteners are getting higher and higher. There are many fasteners used under the conditions of maximum, minimum, ultrahigh temperature, ultralow temperature, ultrahigh speed and ultralow speed. The manufacturing technology of these fasteners is quite different from that of ordinary fasteners. 。 Ultranormal manufacturing includes two meanings: one is to produce fastener products used in ultranormal conditions; the other is to produce the process and technology of manufacturing these fastener products. It can be predicted that in the future, ultraprecision manufacturing, ultrahigh performance product manufacturing and ultraforming technology will be the symbol of the level of fastener manufacturing, and will become the focus of research and development direction of high-end fastener manufacturers.
