Precision Wire Forming-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
