What is the purpose of draw spring?


Given the constraints it will have to face, the draw spring must combine flexibility and strength. Draw spring manufacturing therefore requires special expertise from its conception upon its realization.


A draw spring is designed to "pull." It is primarily used as a return spring in various mechanisms. With its two loops to install it, the spring is stretched by tensile stress and then contracts so that the mechanism take return back its original position, or to maintain a system’s balance. There are two types of draw springs: unclosed German loops spring, tougher, and closed English loops draw spring which is suitable for low traction.

Springs too often remain disregarded; however, they are major components for a large variety of objects for everyday use. Among the very numerous goods whose correct functioning necessitates one or several small springs, one can find bottles of perfume, shock absorbers, lighters, watches, robots, but also industrial machines. The high mechanical and sometimes thermal or chemical stresses to which springs are subjected combined to their small size compliance with very high quality standards is mandatory during the manufacturing process. For leading-edge sectors, such as pharmaceutical, high-tech industries, automotive, and other cutting-edge sectors, it is of the utmost importance that the springs that make up their products are of the highest degree of quality.
