Detailed Product Description

Thickness: 0.15 ~ 20mm

This is a type of spring in which the wire or steel band is wound 
into a plane helical. One end of the spring is fixed, while the 
other end, once being subjected to a given torsion, will generate 
an elastic bend deformation by which the spring will twist within 
its plane. The more the turns, the larger the deformation angle,
and the higher the stored energy.

This type of product is usually used as a compacting spring or 
energy-storage spring in instruments, watches and clocks.
