Our power spiral torsion springs are fabricated from steel strips tightly wound into flat layered spirals. They store torsional energy, generating greater torque the more they are coiled.
Common application scenarios include self-retracting tape measures, automotive seat belt retractors, wire winders, starter motors, clocks, watch movements and toy internal mechanisms.

Variable force clockwork springs are widely used in daily life. The video demonstrates their application in retractable safety barrier belts.

Unlike ordinary springs that follow Hooke’s Law (where pulling force is proportional to deformation), variable force clockwork springs can be engineered to deliver non-linear force curves such as increasing force, decreasing force or stepped force changes over the stroke.

Leveraging this mechanism, variable force clockwork springs also serve a broad range of scenarios including automotive safety seatbelts, backpack fastening straps, lifting brackets, window blinds, shelf pushers and many more.

Before delivery, our flat spiral power springs undergo full-automatic load testing.
Precision machinery compresses each spring automatically to check elasticity, stiffness, permanent deformation and uniform dimensions. Every product is inspected to keep steady rebound strength and prevent early force loss.
We maintain tight quality control during production, so all springs perfectly match the technical parameters on your drawings.
