Spiral Springs

Inspired by nature

Specialists in complex spiral spring analyzed using FEM tools

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.

Spiral Springs

Advantages and benefits of spiral spring

  • Nature as an inspiration: the spiral is a natural shape, frequently found in nature, that evokes the evolution of a force, of a state.
  • Analyzed using FEM/FEA analysis and validated on fatigue test benches
  • Improved by use of shot peening

Measures

  • Strip thickness: 0.05-12 mm (0.002-0.4 in)
  • Strip width: 2-120 mm (0.08-4.7 in)

Materials

The choice of the right material, surface treatment and coating are critical for the final quality and safety of the product. From stainless steels to the most specific materials bought in from the best suppliers. 

  • Carbon steel, almost for every application. 
  • Stainless steel, ideal for high stress and fatigue applications. 
  • Inconel  
  • Elgiloy 
  • Hastelloy 
  • Chrome silicon
  • Other materials according to your special requirements
