Compression Springs are open-coiled helical springs designed to
resist a compression force applied along the axis of the coil.
As the coils are compressed from their free length, the spring operating
length is shorten and the compression spring stores energy
or provides a force for the specific application.
Compression springs are our most common spring type, they have very
wide range of applications and could be found in almost all mechanical
products, such as automobile, machinery, automotive equipment, valves, electric switches and so on.
Extension springs are widely used in machineries, automatic devices,
power transmission, door locks, etc. The ends are normally different types
of end loops and hooks, there are also a wide range of other mechanical
attachment possibilities, such as coiled in and screwed in attachments.
Torsion Springs are important component in many industry,
such as seat belt locks, boot lid springs, backrest springs in cars and so on.
