Variable force springs are designed for applications where force output needs to change through the working stroke. They can support progressive movement, controlled return, and product mechanisms that require different force levels at different positions.
Common applications
- Products requiring progressive or changing force
- Sliding, lifting, or return mechanisms with changing load
- Compact devices where constant force is not suitable
- Custom motion-control structures
Custom design information
For custom variable force springs, key inputs include the force curve, stroke length, start force, end force, installation space, cycle life, and product load conditions.

FAQ
When should a variable force spring be used?
Use it when the mechanism needs different force levels during movement instead of a flat constant force.
Can the force curve be customized?
Yes. The force curve can be designed according to product load, stroke, material, and spring geometry.
What information is needed for design?
A target force curve, stroke length, installation space, cycle life, and working environment help guide the design.
