Our custom double torsion spring, also named LED downlight clip spring and lighting fixture torsion spring, is a dual coil torsion spring clip specially engineered for lamp fixing and clamping. Produced by fully automatic CNC spring coiling machines, this carbon steel nickel plated torsion spring integrates two symmetrical torsion coils with long torsion arms and a middle connecting bridge, delivering balanced bidirectional clamping force for LED lighting fixtures.
As a reliable OEM manufacturer, we support full custom service to adjust wire diameter, coil turns, arm length and torsion force according to client drawings or samples. Each batch undergoes heat treatment, deburring polishing and semi-bright nickel electroplating to achieve smooth anti-rust surface and outstanding repeated opening & closing fatigue resistance. All finished double torsion springs pass torsion sorting inspection to eliminate deformed parts and guarantee uniform elasticity for mass lighting assembly.

- Indoor & outdoor lighting fixture fixing clips (lighting fixture torsion spring)
- Panel light, ceiling lamp, spot light assembly locking parts
- Small household electrical equipment elastic clamping buckles
- Electronic equipment plastic shell snap fastener torsion springs
- Home appliance elastic buckle & lightweight equipment clamping components
As a professional torsion spring OEM manufacturer, we provide full one-stop custom service for all types of double torsion spring and dual coil torsion spring clip:
- Sample & drawing custom development: Accept client technical drawings, physical samples to customize LED downlight clip spring size, torsion force and shape.
- Material customization: Switch stainless steel, carbon steel, alloy spring wire per application demand.
- Surface finish custom: Matte nickel, bright nickel, zinc plating, passivation available besides standard semi-bright nickel.
- Dimension adjustment: Custom wire diameter, coil count, torsion arm length, overall length & width.
- Torsion force tuning: Adjust spring tightness to match lighting fixture clamping requirements.
- Small batch & mass production support, flexible MOQ for custom lighting fixture torsion spring orders.
- Balanced dual torsion design solves uneven clamping force issue of single coil springs, avoids lamp falling off.
- Heat treatment eliminates internal stress, resolves short service life & spring fatigue breakage after frequent opening.
- Precision CNC forming ±0.05mm tolerance fixes inconsistent spring size causing assembly mismatch.
- Semi-bright nickel plating solves rust & discoloration problems in humid lighting installation environments.
- 100% torsion sorting inspection removes deformed springs, reduces client assembly rejection rate.
- Custom service adjusts torsion force freely, eliminates trouble of finding non-standard lighting fixture torsion spring suppliers.
- Deburr polishing removes sharp wire cuts, prevents scratching lamp housing during installation.
- Raw material incoming inspection: Test tensile strength & hardness of 65Mn/1070 carbon steel wire before production.
- In-process CNC forming dimension monitoring: Real-time size detection for double torsion spring coils & torsion arms.
- Heat treatment quality check: Hardness test to ensure stress relief & fatigue performance.
- Full deburr & polishing inspection: No sharp edges or burrs left on dual coil torsion spring clip surface.
- Electroplating layer thickness & uniformity test for carbon steel nickel plated torsion spring.
- Finished product torsion sorting: 100% elasticity screening to reject angle deformed parts.
- Random sampling fatigue cycling test: Simulate lamp repeated disassembly to verify long service life.
- Final packaging visual inspection to avoid scratch & damaged LED downlight clip spring.
