As a reliable custom torsion spring manufacturer with full OEM custom service, we produce premium stainless steel double leg torsion spring crafted from grade 304 stainless steel wire. This small precision rotational torsion spring features two different-length torque arms, engineered to deliver consistent rotational torque for daily hardware, cabinet hinges, automation fittings and plastic buckle assemblies. Our full manufacturing workflow includes CNC numerical spring coiling, low-temperature stress relief tempering, wire end deburring, ultrasonic degreasing, mechanical mirror polishing and stainless steel passivation treatment. Every stainless steel hinge torsion spring undergoes strict full inspection to guarantee consistent size tolerance, stable torsion force and long anti-fatigue service life. We accept custom drawings and sample-based production to match unique equipment assembly requirements for global industrial buyers.
Custom packaging, private label marking for bulk OEM orders
Free pre-production prototype trial before mass manufacturing
Flexible MOQ support for small batch & large volume orders
Product Advantages
Low-temperature tempering eliminates internal forming stress: Solves unstable torsion force and easy deformation issues of ordinary small precision rotational torsion spring after repeated rotation
Mirror polishing + passivation double surface process: Fixes scratch, rust and corrosion problems of untreated stainless steel double leg torsion spring in humid working environments
Precision CNC integrated molding: Avoids uneven coil spacing and inconsistent arm size tolerance of manually bent torsion springs
Full wire end chamfer deburring: Eliminates sharp burr scratch risks during assembly
Strict torsion force full inspection: Resolves batch torque inconsistency which causes hinge reset failure
304 stainless steel raw material: Prevents rust failure for stainless steel hinge torsion spring used in damp daily & light industrial equipment
Quality Control
Raw material incoming inspection: Chemical composition & wire hardness test for 304 stainless steel wire
In-process dimensional spot check during CNC coiling & arm bending
Final full inspection: All finished products test dimension tolerance, torsion force, surface appearance, burr removal
Finished product aging torsion cycle test to verify anti-fatigue performance
