Compression spring can be seen everywhere in life, and compression spring is also the most widely used one of all spring types. The products are widely used in electronics, motors, computers, information, motorcycles, bicycles, hardware tools, gifts, toys, and even national defense industry. Because its design and principle are easy to master, manufacturing control is also the most simple.

    Compression spring is a kind of hardware fitting with spiral geometry formed by line. It bears the pressure. The material section it uses is mostly round, and it is also made of rectangle and multi strand steel. The spring is generally of equal pitch. The shapes of compression spring are: cylindrical, conical, medium convex and medium concave, and a small number of non-circular, etc. between the rings of compression spring are A certain gap, when subjected to external load, the spring shrinks and deforms, storing the deformation energy.

    The shape of compression spring mainly includes: cylindrical, conical, convex and concave, a small number of non-circular and even various end variants. All products need to be shaped according to the design, etc. there is a certain gap between the rings of compression spring. When subjected to external load, the spring shrinks and deforms, storing the deformation energy. With complete testing equipment and instruments, the quality of spring products can be controlled effectively.
