105MM Body Length Tension Coil Springs For Plastic Extruding
|Material||Spring steel 82B|
|Surface treatment||zinc coating|
|Usage||plastic extruding machine|
Our tension 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.

your unique application.
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

Q) For Extension Springs, what is free length and how is it measured?
A) Free length is the overall dimension of an extension spring in the
unloaded position. The free length is measured from the inside of
one end loop (or hook) to the other and can be varied by changing
the end configuration without changing the number of coils.
Q) How does stress relieving or heat treating affect extension
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
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
