105MM Body Length Tension Coil Springs For Plastic Extruding Machine

Specifications:

Description:

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.

FAQ:

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 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.
