A pressure spring is under pressure to the spiral spring, because it can bear the pressure of both ends can be open or closed or around the flat and smooth, material section in which were round, rectangular and is also useful Multi Strands steel rayon coiled spring, such as pitch and pitch shape, compression spring a: cylindrical, conical, concave and convex and non circular and a small amount of the end of the variants, can need according to the design of molding products, there is a certain gap between the ring and the ring compression spring, spring shrinkage deformation when subjected to external load, deformation energy storage.
The pressure spring (Compression Spring) is a kind of all kinds of spring in the most widely used, using a wide range of electronic products, and motor, computer, information, automobile and motorcycle, bicycle, hardware tools, gifts, toys, and even the national defense industry, because of its design principles and easy to grasp, is also the most simple manufacturing control
