There are four major problems that restrict the development of the fastener industry in China:
Due to the early development of the fastener industry, it has obvious geographical features. It has always been a very traditional industry. However, the application of fasteners is extremely extensive and has penetrated into many industries.
The first problem is the 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 related backward technology. Such as: cold heading steel cold heading steel is mainly used for the manufacture of bolts, nuts, rivets, bolts and other fasteners, its chemical composition, high metallurgical requirements, the current annual demand for cold heading steel is about 1 million tons Among them, the auto industry needs 100,000 tons, but due to technical and other reasons, only 300,000 tons of domestically-made cold-headed steel wires are currently imported, and nearly 700,000 tons are imported each year. According to relevant department statistics, φ6.5mm or less needs 150,000 tons, φ8mm needs 160,000 tons, and φ9mm and φ14mm each require 80,000 tons. The current domestic market is in short supply.
The second is the low level of technology and equipment.
There is no guarantee of consistency in product quality. Mechanical basic parts are generally batch and mass-produced products, as well as products with many varieties and processing accuracy requirements. Therefore, the production process and equipment thereof require high requirements and investment. In many foreign countries, high-efficiency and high-precision special planes, production lines or flexible lines are used to achieve efficient and automated production.
The third issue is the key manufacturing and testing equipment.
Mechanical universal parts have high requirements for dimensional accuracy consistency, performance reliability, and interchangeability of each part, allowing only a very small number of products to be out of tolerance, and have passed inspections to remove unqualified products from the factory, if not High-precision and high-efficiency equipment can hardly survive and develop in a fierce competition. At present, the key equipment of China's parts and components manufacturing enterprises is mainly dependent on imports. Due to the large wear and tear on equipment, equipment needs to be constantly updated and reconstructed. While imported equipment and spare parts are expensive, if you want to accelerate the pace of development of the industry, you must solve the key equipment problems as soon as possible.
Fourth, the speed of new product development.
China's mechanical parts and components industry lags behind in foreign countries in terms of technological innovation and new product development. In particular, SMEs lack technology and talents, lack funds and necessary equipment, and lack relevant information and technology exchanges, resulting in long-term tracking and At the imitation stage, there are few intellectual property rights of the company. Currently, there is not much research on product development, and there are few independent research and development forces in the company. This is a key issue for the continued development of the industry.
