Clockwork 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

Constant Force

<±5% variation vs ±15-20% in conventional springs.

Long Stroke

Delivers up to 30m linear travel per spring.

Compact Storage

12mm min coiled diameter saves 90% space.

Quiet Operation

Special lubrication keeps noise <30dB.

Maintenance-Free

Stainless steel + self-lubricating design.

How They Work

As spring unwinds from spool, bending stress generates constant force; rewinds automatically when released.

Key Characteristics

✔️

Materials - 301/304 stainless standard, 17-7PH high-strength

✔️

Force Range - 0.1-50N customizable, 500N/m max load per width

✔️

Life Cycle - 50k cycles standard, 100k for medical grade

Key Design Factors

✔️

Radius Ratio – Spool diameter/thickness ratio 50-100:1

✔️

Stress Analysis – FEA confirms max stress <70% yield strength

✔️

Fatigue Test – 100k extension-retraction cycles for dynamic

Manufacturing Process

Slitting

Precision cutting to ±0.02mm width tolerance.

Edge Finishing

Laser deburring for Ra<0.4μm smoothness.

Pre-Stressing

Special rollers impart initial curvature.

Heat Treatment

350℃ vacuum annealing relieves stress.

Coating

Nickel/Teflon coatings reduce friction.

Testing

100% force curve and fatigue life verification.
