Stamping Blanks-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

Material Efficiency

Nesting optimization reduces scrap by 40%.

Dimensional Stability

Pre-hardening guarantees ±0.03mm thickness tolerance.

Surface Quality

Mirror finish (Ra0.2μm) reduces die wear.

Batch Consistency

Auto-sorting ensures 99.9% dimensional uniformity.

Quick Changeover

Standardized interfaces enable 5-minute die change.

How They Work

Precision rolling, shearing and heat treatment processes transform metal coils into standardized blanks with optimized dimensions, hardness and surface properties for stamping.

Key Characteristics

✔️

Material Range - Covers 0.1-6mm stainless, carbon steel and alloys

✔️

Width Tolerance - ±0.05mm precision slitting

✔️

Hardness Control - Adjustable HRC20-50 for various stamping needs

Key Design Factors

✔️

Grain Direction – Rolling direction must align with stamping forces

✔️

Edge Quality – Laser cutting maintains burr height < 0.01mm

✔️

Stress Distribution – Vibration aging removes 98% internal stress

Manufacturing Process

Material Inspection

Spectrometry verifies composition.

Uncoiling

Constant tension prevents deformation.

Laser Cleaning

Removes oxides and oils.

Multi-pass Rolling

20-roll mill controls thickness.

In-line Annealing

Controlled atmosphere heat treatment.

Slitting: Diamond

tools achieve ±0.02mm width.

Surface Treatment

Electropolishing/coating.

Packaging

VCI paper + vacuum sealing.
