Details:According to the force nature, the spring can be divided into tensile spring, compression spring, torsion spring and bending spring. According to the shape, it can be divided into disc spring, ring spring, plate spring, spiral spring, cone scroll spring and torsion bar spring, and can be divided into cold coil spring and hot coil spring according to the process of production. The ordinary cylindrical spring is simple in application and can be made into various types according to loading conditions. In general, the material of the spring should have high elastic limit, fatigue limit, impact toughness and good heat treatment performance, such as carbon spring steel, alloy spring steel, stainless steel spring steel, copper alloy, nickel alloy and rubber. The methods of producing spring are cold roll and hot coil. The spring coil diameter less than 8 mm is generally used in cold coil method, and the coil method is larger than 8 mm. Some springs are pressed or shot peening after they are made, which can improve the bearing capacity of the springs.A compressed spring (compression spring) is a spiral spring that bears the direction of pressure. The cross section of the material is mostly circular and is also made of rectangular and multi strand steel. The spring is usually equal to equal pitch. The shape of the compressed spring is cylindrical, conical, middle convex and middle concave, and a small number of noncircular circles, and compress the ring and ring of the spring. There is a certain gap between them. When the external load is applied, the springs shrink and deform and store the deformation energy.The compression spring is one of the most widely used springs. The cross section of the material is mostly circular and is also made of rectangular and multi strand steel. The spring is usually equal to equal pitch. The shape of the compression spring is cylindrical, conical, middle convex and middle concave, and a small amount of non circular. It can be divided into a cylindrical spiral compression spring, a non circular spring coil spring and nonlinear. A variety of compression springs, such as characteristic spiral spring, multi strand helical compression spring and rectangular spiral compression, can be divided into cold coil spring and hot coil spring according to the manufacturing process.

With the rapid development of business simultaneously, AFR Precision always keeps the balance between external opportunities and internal management, attaching great importance to the training and shaping of core competitiveness. The company will take customer service value as the core competitiveness of enterprises. Adhering to spirit of enterprise:acting with integrity , pursuit of excellence, respect for the individual , AFR Precisionstrives to provide customers with Promising future tension springs exporter.
