Wave Spring-Precision Spring

Precision Hardware

Forging industrial backbone with micron precision, LH Hardware delivers end-to-end solutions for global advanced manufacturing – from precision springs, custom springs to stamping, shafts, and linear motion systems

Precision Springs

High-precision springs manufactured via CNC coiling or cold forging, featuring tight tolerances (±0.003mm) and superior fatigue resistance, ideal for automotive suspension and precision instrumentation requiring consistent load-bearing performance.

Special Springs

Custom-engineered springs for extreme conditions, such as high-temperature (up to 300°C) or corrosive environments (titanium/hastelloy), used in aerospace hydraulics and nuclear reactor dampers

Wire Forming

Multi-station cold heading process forming wire (Φ0.1-3mm) into precision parts (connectors, snaps) with ±0.02mm tolerance, serving 5G infrastructure and smart home applications

Precision Stamping

Micron-level stamping (Ra≤0.4μm) of 0.05-3.5mm metal sheets via progressive dies, producing EMI shields and battery contacts for semiconductor and EV battery modules

Precision Shafts

Ultra-precision ground shafts (Ra≤0.2μm) with ±0.002mm diameter tolerance, employed in robotic joints and CNC spindles for ±0.005mm repeatability

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.
