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
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 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.

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
Q) What needs to happen for an extension spring to have no initial
A) The Extension Spring needs to be designed with space between the
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
