Due to the early development of the fastener industry, and has obvious regional characteristics. It has always been a very traditional industry, but the application of fasteners is extremely extensive and penetrates into many industries. There are four major problems that restrict the development of China's fastener industry: The first is the problem of backwardness of raw materials and related technologies. An important reason for the poor quality of fastener products is the poor quality of raw materials and the backwardness of related technologies. For example, cold heading steel wire cold heading steel is mainly used to manufacture bolts, nuts, rivets, bolts and other fasteners. Its chemical composition and metallographic structure are relatively high. The current annual demand for cold heading steel is about 1 million tons. The automobile industry needs 100,000 tons, but due to technical reasons, the domestically produced cold-rolled steel wire is only 300,000 tons, and it is imported nearly 700,000 tons per year. According to the statistics of relevant departments, 150,000 tons is required for φ6.5mm, 160,000 tons for φ8mm, and 80,000 tons for φ9mm and φ14mm. The current domestic market is in short supply. Second, the level of process and process equipment is low, and the problem of consistency of product quality cannot be guaranteed. Mechanical basic parts are generally batch-produced, mass-produced products, and also have many varieties and processing precision requirements. Therefore, the production process and equipment are required to be high and the investment is large. High-efficiency and high-precision special planes, production lines or flexible lines are used in foreign countries to achieve efficient and automated production. The third is the key manufacturing and testing equipment problems. The mechanical universal parts have high requirements for dimensional accuracy, performance reliability and interchangeability of each part. Only a few products are allowed to be out of tolerance and passed through the factory. Inspection eliminates non-conforming products. Without high-precision and high-efficiency equipment, it is difficult for companies to survive and develop in the fierce competition. At present, the key equipment of China's parts manufacturing enterprises mainly rely on imports. Due to the wear and consumption of equipment, equipment needs to be constantly updated and modified. Foreign imported equipment and spare parts are expensive. If you want to speed up the development of the industry, you must solve the problem of key equipment as soon as possible.

The fourth is the speed of new product development. China's machinery parts industry is far behind in foreign countries in terms of technological innovation and new product development. In particular, SMEs lack technical strength and talents, lack of funds and necessary equipment, and lack of relevant scientific and technological information and technical exchanges, resulting in long-term tracking and In the imitation stage, there are very few intellectual property rights. At present, there are not many researches on product development, and there are few independent research and development forces in the enterprise. This is a key issue for the industry to continue to develop.
