Extension Springs Manufacturer

extension springs, extension spring manufacturer,

An Extension Spring is a mechanical component that is used to create resistance to a pulling force between two opposing components. This type of spring absorbs and stores mechanical energy. The initial tension determines how tightly together the spring needs to be coiled during the manufacturing process.

The initial tension can be manipulated to attain load requirements for any application. The engineering design normally calls for hooks, or eyes, at the ends of the spring which attach to the opposing components. Extension springs are often used to provide return energy to components that extend in an activated position.
