Using CNC spring coiling machines, we can produce custom extension springs with wire diameters from 0.08mm to 35mm in the way of cold wounding and hot wounding.

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, peen shooting and heat-treating are must for extension springs to make sure high quality.

FAQ of extension springs:

 

Q) How does stress relieving or heat treating affect extension springs?
A) It can reduce the spring's initial tension, change the hook's position, or create a change in the spring's diameter.

 

Q) What are three things you can do to maximize the life of an extension spring?
A) The path of the wire should be smooth and gradual as it flows into the end; marks and other stress concentrations should be held to a minimum; and a minimum bend radius of 1 1/2 times the wire diameter is recommended.

 

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.
