How Do We Create Tension Springs?
Tension springs, or extension springs, are one of the most commonly known springs in the spring manufacturing industry. They are tightly wound coils that are designed to operate with tension force.
Tension springs are helical coiled springs designed to bring components together, or for attachment purposes – using loops and hooks – rather than to keep them apart. A high-tension spring works by absorbing energy and storing it and when tension is applied, its energy creates a resistance to counter the pulling force.
The initial tension applied dictates how close these coils are and by controlling this initial tension, it is possible to customise the spring to cater to specific load requirements. The coiled design of a spring is what provides the strength and elasticity. A tension spring is tightly wound and when in a rest state, it remains coiled. We include interfaces such as eyes, hooks or loops at both ends to facilitate attachment to other components.
Common Uses Of Tension Springs
The design, size and flexibility of a tension spring mean it has lots of uses including:
- Garage doors
- The automotive industry
- Trampolines
- Farm machinery
- Vice-grip pliers
- Toys
- Washing and medical devices
As a leading tension spring supplier in the uk, we allow a variety of dimensional ranges to be used and when looking at tension springs for sale, factors such as the material, wire size, finish and ends will determine the appropriate choices.
