Spring used in a wide range of large to a variety of machinery, small to household items, summed up, the main application in the following four industries:
1, to automobiles, motorcycles, diesel engines and gasoline engines based on supporting springs and springs. These springs are valve springs, suspension springs, shock absorbing springs and clutch springs, etc., with a large dosage, accounting for about 50% of the spring production. At the same time the technical level requirements are also high, it can be said that these springs are representative of the technical level, they are mainly to high fatigue life and high resistance to relaxation direction, thus reducing the quality.
2, to railway rolling stock, heavy-duty vehicles and construction machinery, mainly large springs and leaf springs, these springs to hot roll forming is an important aspect of the spring manufacturing industry. With the development of high-speed railways, vehicle shock absorption system upgrades, as the vehicle suspension thermoforming spring technology has improved greatly, these springs are mainly to the direction of high-strength and high-precision development to stabilize product quality.
3, instrumentation-based electronic and electrical springs, typical products such as motor brush springs, switch springs, video cameras and camera springs, as well as computer accessories springs, instrumentation accessories springs. This type of spring in the leaf spring, shaped spring accounted for a large proportion of different products on the material and technical requirements vary greatly. These springs are mainly towards both high strength and miniaturization of the direction of development.
4, daily machinery and electrical appliances mainly hardware springs, such as mattresses, sofas, door hinges, toys, lighters, etc., the demand for such springs is greater, but the technical content is not high, to the small spring enterprises to improve the development opportunities, these springs are mainly miniaturized in the direction of development.
