Tension Springs & Tension Spring Manufacturers

Tension springs are tightly wound coils that are designed to operate with tension. The spring stretches to a specific length as the load/force is applied to it. In an unloaded position, the loops of the spring are touching, with either a loop or hook attached at one end, and it is when this attachment is directed with force that the spring stretches. When these components are pulled apart, usually from either side, the spring tries to hold itself together, causing the springing action, until the force is stopped and it can return to its original form.

The tension springs we manufacture have dimensions of 0.1mm to 26mm and can be created using the hot or cold coiling processes, with both steel and stainless steel. The end types we provide vary from coiled loops or hooks, to screw in fixture attachments. Popular choices include the half hook, extended hook and screw plug.

The initial tension applied to the tension springs can be controlled using the cold coiled process, in which the wire is formed into a spring shape using a computer controlled coiling machine, whilst unheated. Cold coiling gives the tension springs added flexibility which can be more easily achieved than the hot coiling production process.

Examples for uses of tension springs include lever mechanisms and doors. A good example of tension springs in action is the counterbalancing of garage doors.
