Extension 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.

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.



Applications for extension springs include automotive interiors and exteriors, garage door assemblies, appliances,furniture,engineer machines,washing devices, farm machinery as well as thousands of other uses. XULONG’s extension springs come in a wide array of sizes, from small medical devices to off-road machinery brake springs and marine container.
