Springs are commonly used components in the industry. Springs are used in various products ranging from aircraft and warships to mobile phones and cameras. Therefore, the production of springs has a history of hundreds of years. The original spring is only a cylindrical tension-compression spring, which is wound by hand. The technology is relatively immature and the production efficiency is relatively low. It is very difficult to produce large springs on heavy equipment such as trains or tanks.

　　With the increase of industrial products, spring products have also become richer, various special-shaped springs such as: tower (commonly known as battery spring) springs, double torsion springs, etc., in this way, a lot of winding molds are made by conventional manual methods, and a spring needs to be It takes 3 to 8 processes to complete, or even more processes and poor product stability.

　　With the gradual increase in the amount of springs, a number of companies producing spring equipment have appeared in Germany, Japan and other countries where the industry has developed first, and the technology related to spring machines has gradually matured.

　　In mainland China, the production of springs has been hand-made for a long time. With the accumulation of technology, several manufacturers of spring machines have emerged.
