contoured-stampings-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

Complex Curving

Achieves 5-7 directional 3D deformation in single stroke.

Ultra Precision

Maintains ±0.05mm profile tolerance.

Material Efficiency

Smart nesting reduces scrap by 35%.

Surface Quality

Mirror-polished dies deliver Ra0.1μm finish.

Strength Enhancement

Strain hardening increases local strength 40-60%.

How They Work

Metal sheets plastically deform to replicate die contours under hydraulic/mechanical pressure, with controlled material flow to prevent cracking.

Key Characteristics

✔️

Material Thickness - Processes 0.3-6mm various metal sheets

✔️

Forming Depth - Maximum 8-10x material thickness

✔️

Springback Control - AI compensation achieves ±0.2° accuracy

Key Design Factors

✔️

Die Clearance – Optimal 1.05-1.15x material thickness gap

✔️

Blank Holder Force – Multi-zone control with ±2% tolerance

✔️

Lubrication – Nano-lubrication with ±20nm film control

Manufacturing Process

Sheet Pretreatment

Laser cleaning removes surface oxides.

Precision Blanking

Servo cutting ensures ±0.03mm accuracy.

Preforming

30-50% initial deformation creates basic profile.

Fine Stamping

2000-3000T pressure forms final contours.

Trimming/Piercing

5-axis laser cutting finishes edges.

Local Strengthening

Laser shock peening reinforces critical areas.

Dimensional Inspection

Full 3D optical scanning.

Surface Treatment

Nano-coating or electropolishing.
