Torsion Spring Overview
Torsion springs store and release rotational energy (torque) through angular deflection. Commonly applied in hinges, valve actuators, industrial switches, and automotive mechanisms. TOSTA manufactures high-precision, extended-fatigue-life torsion springs widely deployed in automotive, mechanical engineering, electronics, and medical device assemblies.
Product Types
Flat Wire Torsion Springs
Wound from rectangular or flat wire, delivering high torsional rigidity and maximum torque transmission within compact axial envelopes.
Double Torsion Springs
Dual-helix configuration providing doubled torque capacity and balanced, symmetrical load distribution for counterbalance mechanisms.
Internal Double Torsion Springs
Internal helix winding design engineered for ultra-compact radial installations requiring high torque density.
External Double Torsion Springs
External coil configuration delivering superior lateral stability and smooth deflection over extended-travel rotations.
Specialty-Leg Torsion Springs
Custom-formed leg bends (radial, axial, tangential, or offset) tailored to complex mounting brackets and space restrictions.
Custom Engineered Torsion Springs
Fabricated strictly to drawing specifications with non-standard wire sizes, precise leg angles, and high-performance alloys.
