Description:


Extension Springs are defined as a type of spring designed to support tensile or pulling loads. Extension springs are usually close wound and will possess initial spring energy. Typically extension springs have hooks or loops on the ends for securing or fastening to door or other objects.

but with spring coiling machines, we can produce various of custom extension springs with wire diameters from 0.08mm to 60mmin 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, and heat-treating are must for extension springs to make sure high quality.


Applications:


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.

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.
