Wave Springs

A thin, wave-shaped spring providing axial force in compact spaces.

Key Advantages

Space Saving

0.1-3mm thickness, reduces axial space by 30-50% vs coil springs.

Precise Force

Delivers 0.1-5000N force with ±10% tolerance.

Ultra-Thin

Minimum 0.1mm thickness for micro precision devices.

Multi-Wave Design

Single/multi-layer options for varying loads.

Low Friction

Special treatment achieves < 0.05 friction coefficient.

How They Work

When compressed axially, wave peaks flatten to store energy; releasing pressure restores waves to release force.

Key Characteristics

✔️
Materials - 301 stainless for standard, Inconel X-750 for high temp
✔️
Wave Specs - 4-20 waves, 0.5-5mm height customizable
✔️
Surface Treatment - Passivation, nickel plating or Teflon coating

Key Design Factors

✔️
Wave Optimization – FEA determines ideal wave count/height
✔️
Stress Distribution – Max stress < 60% yield strength
✔️
Fatigue Life – 100,000 compression cycles for dynamic use

Manufacturing Process

Strip Prep

Select precision steel strip with required thickness.

Wave Stamping

CNC punch forms waves with ±0.01mm precision.

Heat Treatment

400-500℃ vacuum treatment relieves stress.

End Finishing

Laser cutting ensures < 0.02mm flatness.

Surface Treatment

Electroplating/coating per requirements.

Testing

100% check for force, free height and fatigue life.
