Tension Springs

Tension springs are also called extension springs. A tension spring in action is comparable with a trampoline. The spring uses the tension created by an outside force to pull the components back together, components to which the spring is attached.

The tightly wound coils of the tension spring operate with the force. Tension springs have helical wound coils with a hook, loop, and end coil at its one or both the ends. Based on its end design, the tension springs can be classified in many types.

This spring can be attached from both the ends to the other components creating the tension in the spring which in turn attempts to bring the components back together when they try to move further apart.

The coils of the spring touch and are tightly bound until a force is applied to them. When force is applied, the spring coils are pulled apart as the components are moved in the outward direction.

The process of spring making involves hot and cold coiling procedures.
