Torsion Springs


A torsion spring stores energy and exerts rotational (torque) force through its legs when twisted. GL Springs manufactures custom single and double torsion springs to your exact torque, leg angle, and dimensional requirements — for hinges, levers, latches, and countless rotating mechanisms.

Core Specifications

  • Wire Diameter: 0.1mm – 20mm
  • Outer Diameter: 1mm – 80mm
  • Free Length: 2mm – 400mm
  • Leg Length: 5mm – 300mm
  • Material: Stainless Steel (304, 316), Carbon Steel (SWC, SWP), Alloy Steel (Chrome Vanadium, Silicon Manganese), Brass, Bronze
  • End Types: Straight Legs, Hooked Legs, Offset Legs, Custom Leg Configurations
  • Torque Range: 0.01N·m – 1,000N·m
  • Surface Treatment: Zinc Plating, Nickel Plating, Black Oxide, Passivation, Electroplating
  • Standards: ISO, DIN 2089, ASTM A228, JIS B2704

Applications

Our torsion springs are designed to meet the rotational force needs of various industries, such as:
  • Automotive: Door hinges, seat belts, window regulators, ignition switches
  • Hardware: Clips, pliers, scissors, door locks, garage door mechanisms
  • Electronics: Printers, scanners, cameras, remote controls
  • Medical Devices: Surgical forceps, rehabilitation equipment, diagnostic tools
  • Industrial Equipment: Valves, levers, switches, conveyor systems

    Types of Torsion Springs We Manufacture

Single (Helical) Torsion Springs
One coil body with two legs; the standard choice for hinges, latches and levers.

Double / Dual-Coil Torsion Springs
Two coil bodies joined for higher torque in a compact width.
→See our double/dual-coil torsion spring

Stainless Steel Torsion Springs
304 / 316 for corrosion resistance in medical, marine and outdoor use.
→See our Stainless Steel Torsion Spring

Automotive Torsion Springs
IATF 16949 production for hinges, seat belts, window regulators and switches.

GL Springs Advantages

  • Stable Torque Performance: Advanced testing equipment ensures torque tolerance ≤ ±5%
  • Custom Design Flexibility: Support for special leg shapes, torque requirements, and material grades
  • Long Service Life: Strict material selection and heat treatment process reduce fatigue failure
  • Fast Delivery: 7-day sampling for custom orders, 15-day mass production lead time

Torque Testing and Quality Control

Torsion spring performance depends on consistent torque, leg position, coil geometry and material properties. Depending on customer requirements, our inspection process may include:

  • Wire diameter and body diameter inspection
  • Leg length, leg angle and orientation inspection
  • Torque testing at specified working angles
  • Material and surface-finish verification
  • Fatigue and cycle-life testing
  • Batch identification and production traceability

What materials do you use for springs?

We work with:

  • High-carbon steel (Grade 65Mn/70Mn) – most common for industrial use
  • Stainless steel (301/302/304/316) – corrosion resistance
  • Alloy steel (50CrV/55CrSi/60Si2Mn) – high-temperature resistance
  • Custom materials (available upon request)

Can you produce non-standard springs?

Yes! We specialize in:

  • Custom shapes (Conical, Barrel, Double torsion)
  • Special surface treatments (Electroplating, Powder coating, Electrophoretic coating)
  • Extreme-condition springs (High temperature / Cryogenic)

Can you match competitor samples?

We offer reverse engineering services:

  1. Send samples (3–5 pcs ideal)
  2. We’ll analyze material & performance
  3. Provide matched prototypes within 7 days

Do you provide free samples?

  • Existing catalog items (≤5 pcs): you only pay actual shipping cost.
  • Custom sample service: $50 refundable fee (deducted from future orders).

How long does it take for samples?

Typically 5-7 business days. Depends on your request.
