WINDING

A torsion spring can be closed- or open-wound and usually is designed to wind up. As a torsion spring winds up, the coil diameter will decrease and the body length will increase. Read more on the direction of spring winding in our technical articles.

SPRING LOAD

It is important to consider the direction of loading when designing bends or forms off a spring's body or in spring legs. Favorable residual stresses can be created when bends are loaded in a direction that reduces the radius or curvature.

DESIGN

With new manufacturing techniques, torsion end positions can be held to surprisingly close tolerances. Older-design free angle tolerances often do not apply. Aofeng is a torsion springs manufacturer whose facilities employ modern forming machinery and production techniques that allow for an infinite variety of torsion spring end shapes. When specifications call for very long spring legs, we recommend discussing your requirements with a Newcomb sales engineer. Our staff can verify manufacturing capabilities and will work to keep your production costs as low as possible.
