Although the valve spring industry is a small industry in the entire manufacturing industry, its role cannot be underestimated. The country’s industrial manufacturing and automobile industry should accelerate development, and the spring industry, as one of the basic parts and parts, needs an advanced stage of development to adapt to the rapid development of the country’s entire industry.
In addition, the expansion of the scale of spring products and the improvement of the quality level are also the need for the upgrading of mechanical equipment and the need for the improvement of the performance of the supporting mainframe. Therefore, the development of the entire country's industry, spring products play an important role.
With the continuous development of my country's automobiles, tractors, internal combustion engines, motorcycles, mopeds and electrical industries, the variety and quantity of springs are gradually increasing. Although the market demand is very large, the industrial structure of my country's spring industry is quite worrying!
For the spring industry, there has been a passive situation of oversupply of low-grade ordinary springs and high-grade products (high strength, high stress, heterosexual parts, special materials) in short supply for a long time. At present, the output of my country's spring industry has become saturated. According to expert statistics, my country's annual output of springs has reached 4 billion pieces. There are 21 major categories of various spring products with more than 1,600 varieties, mainly valve springs, suspension springs, Diaphragm springs, damping springs, precision springs, automotive interior springs, automotive seat springs, hydraulic springs, oil pump springs, disc springs, high temperature springs, circlips, extension springs, torsion springs, compression springs, scroll springs, and heterosexuals Spring etc.
At this stage, my country's spring products are mostly low-tech general springs. High-tech products such as heterosexual parts and cross-section products can only be produced by a few large-scale factories. The following is a quoted fragment: According to the data of the National Bureau of Statistics, the number of industry enterprises in 1998 was about 541, including 15 joint ventures, 4 sole proprietorships, 10 research institutes, and 37,208 employees (annual average number) (including engineering and technical personnel) 3000 people), the total industrial output value is 2.348 billion yuan, the industrial added value is 680 million yuan, the profit is 57 million yuan, the profit and tax is 170 million yuan, the original value of fixed assets is 1.157 billion yuan, the net value (annual average balance) is 742 million yuan, and the export earns 1,000 yuan. More than ten thousand U.S. dollars, 21 categories of products, more than 1,600 varieties, total labor productivity of 63,117 yuan/person·year. It is estimated that there are more than 1,700 companies in the industry with an output of 4 billion pieces. The annual sales of spring manufacturers, spring manufacturers, and spring manufacturers are 8 billion yuan.
