Spiral Springs

Our engineering team collaborates with your engineers to study, design and create the perfect tailor-made spiral spring your highly dynamic application requires. We are proud to say that we are a global leader in the manufacture of spiral springs. Cam-phase systems associated with motor management (Variable Camshaft Timing Powertrain – VCT) is the most typical application, so they are exposed to high dynamic loads. Spirals have imaginative shapes, inspired by nature, which reduce contact between the loops to prevent premature breakage and exert improved hysteresis control.

FEM/FEA analysis is critical and the next step after this is always to validate spirals on fatigue test benches with the final assemblies to verify their final performance. We can manufacture spiral springs in torsion spring machines or using bending technology depending on the shape and the annual quantities.
