The battery spring

Spring as an important component in the industrial system, there is a large amount of use, and a wide variety of spring production, so the original manual production, gradually moving towards automation. In China 90 years ago, there were only a few professional spring machinery and equipment manufacturers in the spring industry. With the increasing market of spring, professional spring equipment companies gradually entered China, such as Taiwan's northeast spring machinery (EN qiaoding) and guanghong (KHM) gradually occupied the mainstream spring production market. Northeast EN502 universal machine spring manufacturing equipment, is the use of proprietary mechanical institutions, convenient and fast production of various springs, shaped elastic components.

Spring guanghong equipment is the production of compression spring and tension spring high-speed equipment. There are also many professional spring equipment manufacturers abroad such as wafios, MEC(now ORII&MEC) and so on. Domestic production of large spring CNC hot coil machine or blank. Spring industry in the whole manufacturing industry, although it is a small industry, but its role should not be underestimated. The expansion of spring production and marketing scale, the increase of varieties, the improvement of quality level is also the need of upgrading of mechanical equipment and supporting host performance improvement. Therefore, for the development of the entire national industry, spring products have played an important role. Since the reform and opening up, with the globalization of economy and the establishment of China's manufacturing power, the demand for spring accessories has surged. In addition, the investment in spring production is not high, the technical threshold is low, and the investment returns quickly. Since the 1980s, the number of spring production enterprises has increased rapidly. By the end of 2010, there were 724 large-scale enterprises engaged in the spring manufacturing industry in China, with more than 100,000 employees. In 2010, the sales revenue exceeded 30 billion yuan, and the total profit exceeded 1.6 billion yuan. Spring as competition is full of products in the market, low-end products domestic companies have cost advantages, has a certain competitive in price, high-end products of foreign capital and joint venture enterprise technical advantage, cutting-edge products, such as the elastic support is used in the treatment of cardiovascular disease, for foreign medical giant monopoly, almost all domestic enterprises. Automotive spring is the most heated domestic and foreign enterprise market competition, domestic and foreign enterprises have their own strengths, difficult to distinguish each other. Spring industry from the past price war, service competition has gradually entered the industry chain competition, and the industry chain is to rely on standardized means to complete. Although the industry standard system is perfect, but because of the earlier, the considerable distance from the market demand, especially compared with the developed countries such as Japan, Europe, the United States, the current national standard and industry standard is low, also caused the domestic spring products in the international market competitiveness is not strong, therefore, come as soon as possible in line with international standards of new industry standards is the most important of the industry needs to solve. During the 12th five-year plan period, China's automobile, railway, instrument and other industries will maintain rapid and stable development, thanks to the national policy stimulus and the revitalization plan of relevant industries. In addition, some emerging industries, such as conventional weapons, nuclear power and aircraft manufacturing, are short of the participation of springs. With China's growing national strength, the investment in national defense technology is increasingly abundant, which is also an important aspect of spring industry business opportunities. Under the background of good external environment and stable growth of downstream demand, China's spring industry will maintain rapid and stable development. It is expected that by the end of the "twelfth five-year plan", that is, 2015, China's spring industry sales are expected to reach 60 billion yuan.
