Application of spring Nantong Xingyu spring Limited production is extremely wide, with the rapid development of high-speed railway, vehicle damping system upgrade, as the thermal spring forming technology of vehicle suspension has greatly improved.

Daily necessities industry and hardware industry, including lighters, toys, locks, door hinges, fitness, mattress, sofa and so on, in terms of quantity, the maximum demand for spring, tens of billions of pieces of technical requirements is not high, the price is very low, generally by the scattered throughout the small spring factory production, they are unique advantages in cost, big spring plant is difficult to compete with them.

There is also a major potential market for the spring industry is the railway system. With the deepening of the reform of the railway system, the implementation of the market is gradually opening up and high speed railway planning, vehicle suspension system facing the upgrading of railway line to install the new damping element, will give the spring industry to bring enormous business opportunities. Some spring enterprises are listed as the Ministry of Railways high-speed train spring fixed-point units, there are units in the development of rubber metal composite spring for high-speed rail track vibration and noise reduction. At present, the market of railway system has just begun to open to the outside world, although the degree of openness is not large, but the potential is considerable. Large spring and spring plate to railway locomotives, trucks and construction machinery, the spring coil forming, is an important aspect of spring manufacturing. A small number of small and medium-sized enterprises will be the main direction of high strength and high precision to stabilize product quality.
