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 Spring

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 Spring

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 Spring

Torsion Springs are important component in many industry,

such as seat belt locks, boot lid springs, backrest springs in cars and so on.
