Wire Bending-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

High Precision

Forms intricate 3D shapes with multiple angles/radii.

Complex Geometry

Reduces material waste by 90% vs machining.

Material Saving

Reduces material waste by 90% vs machining.

Quick Changeover

CNC program switching in under 5 minutes.

Surface Protection

Non-cutting process preserves wire surface.

How They Work

Wire is fed through guides while bending dies and rotating arms create precise plastic deformation at programmed locations.

Key Characteristics

✔️

Materials - Processes 0.1-12mm steel, copper, aluminum wires

✔️

Angle Accuracy - ±0.5° bending angle tolerance

✔️

Radius Control - Minimum 1xD bending radius

Key Design Factors

✔️

Springback Compensation – 0.5-5° over-bending based on material

✔️

Die Clearance – 5-10% of wire diameter clearance

✔️

Feed Rate – Optimized 10-50m/min based on wire size

Manufacturing Process

Wire Prep

Select straight wires of required material/diameter.

Feeding

Servo motor feeds wire to precise position.

First Bend

Station 1 forms basic angles.

Secondary Forming

Subsequent stations add complex features.

Cutting

Hydraulic shear separates finished part.

Inspection

CCD vision checks 100% dimensions.
