Description:
Tension springs are similar to compression springs but are loaded in tension. Hooks or loops are made to allow a force to be applied, as extension springs are usually attached at both ends to other components. When these components move apart, the spring tries to bring them together again. Extension springs are wound to oppose extension and the tension of the wind can be manipulated to achieve the load requirements for a particular application.
Our tech dep can design springs to have initial tensions according to the load requirement of your applications. We will also validate spring designs before manufacturing, and secondary processes such as color-coding, plating, and heat-treating are must for extension springs to make sure high quality.

FAQ:
Q) Concerning extension springs, where do most failures occur?
A) Most extension spring failures occur in the area of the end. To
maximize the life of the spring,
the path of the wire should be smooth and gradual as it flows into
the end.
Q) What needs to happen for an extension spring to have no initial
tension?
A) The Extension Spring needs to be designed with space between the
coils.
Q) Concerning an Extension Spring - What has to occur for the coils to
start to open?
A) The force that keeps the coils closed, known as the Initial
Tension, must be overcome to allow the coils to start to open.
Q) What is the function of an extension spring?
A) To provide extended force when the spring is pulled apart from its
original length.
