Compression 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

Precision Motion Control

Compression springs deliver consistent resistance, perfect for applications requiring exact force measurements and controlled movements in mechanical systems.

Self-Resetting Mechanism

These springs automatically return to original position when pressure stops, making them essential for latches, switches and safety devices.

Secure Electrical Connections

Maintaining steady contact pressure ensures reliable power transmission in battery compartments and electronic connectors.

Optimized Strength & Weight

Advanced coiled steel construction provides exceptional force capacity while minimizing weight for space-sensitive applications.

Cost-Effective Solution

Affordable steel materials and simple design offer long-lasting performance with minimal material requirements.

Maintenance-Free Performance

Operating without lubrication or special care, these springs provide reliable performance through millions of cycles.

How They Work

Compression springs operate based on Hooke’s Law (F = -kx), where the force exerted is proportional to the displacement. When an external load is applied, the spring’s coils compress, storing elastic potential energy. Upon release, the stored energy causes the spring to rebound to its original shape.

Key Characteristics

✔️

High Load Capacity - Resists significant axial forces without permanent deformation

✔️

Precision Movement - Provides controlled, predictable resistance

✔️

Long Service Life - Engineered for millions of cycles with minimal fatigue

Key Design Factors

✔️

Wire Diameter – Thicker wire = higher stiffness

✔️

Coil Diameter – Narrower coils = greater force resistance

✔️

Material – Music wire, stainless steel, or high-tensile alloys

✔️

Active Coils – More coils = softer spring rate

Manufacturing Process

Coiling

Wire is straightened and fed into CNC machinery that forms it into springs with precise dimensions. High-speed cameras ensure accuracy during production.

Stress Relieving

Springs are heated in ovens to solidify their shape and create metallic links, then slowly cooled to remove brittleness caused by coiling.

Finishing

Multiple processes prepare springs for specific applications:

Grinding: Flattening ends for better surface contact
Strength Peening: Prevents metal fatigue
Setting: Compressing to establish final dimensions
Coating: Zinc, chromium, or paint for corrosion resistance
Packaging: Custom packaging for protection
