Whether in industrial manufacturing or in daily work and life, we can see all kinds of springs being used in various places. There are many types of springs. Compression springs and extension springs are two common forms of spring products. These two forms of springs have certain similarities in appearance and effect, but in essence, these two types of springs are still different. In the following content, the editor of Shiruida will introduce compression springs and extension springs in detail.

　　1. Extension spring

　　A tension spring is a helical spring that bears axial tension. It is usually made of round cross-section material. When not subject to load gravity, the coils of the tension spring are generally tight and there is no gap between them.

     Do you know the difference between compression springs and extension springs?

　　2. Compression spring

　　A compression spring is a helical spring that withstands axial pressure. Most of the cross-sections of the materials used are circular, but there are also rectangular and multi-strand steel windings. The springs are generally of equal pitch. The shapes of compression springs usually include: cylindrical, conical, convex and concave, as well as a small number of non-circular shapes. There is usually a certain gap between the coils of the compression spring. When subjected to external loads, the spring contracts and deforms to store deformation energy.

　　The above is a detailed introduction to the two most common types of springs, namely extension springs and  compression springs . I hope it will be helpful to you!  http://www.sklspring.com/
