A proper extension spring design will not only store energy and offer resistance to a pulling force, but do so reliably. Extension springs, also known as tension springs, typically have hooks, loops, or end coils that can be attached to separate points and then used to pull the spring apart. They usually have a constant diameter body. Also sometimes, they are barrel shaped. When required, Xulong Spring can make a custom extension spring design that incorporates extended or special shaped hooks

Our extension springs are available with different end configurations to facilitate the attachment to components being acted upon. End configurations that we offer include full loop,machine hook,coned end with swivel hook or bolt,crossover hook and custom shaped hook.

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.

Q) What is the function of an extension spring?
A) To provide extended force when the spring is pulled apart from its original length.


Q) Most extension springs are wound with initial tension. What is initial tension and what is the measure of it?
A) Initial tension is the internal force that holds the coils tightly together. The measure of the initial tension is the load necessary to overcome the internal force and just start coil separation.


Q) How do extension springs absorb and store energy?
A) By offering resistance to a pulling force. Various types of ends are used to attach the extension spring to the source of the force.
