Spiral Torsion Spring

Spiral Torsion Spring forms from material coiled along a flat-plane spiral layout. Applied twisting stores rotary torque within this planar structure. It occupies limited radial space and allows larger rotation angles than conventional cylindrical torsion springs. Layer spacing stays controlled to avoid rubbing or sticking during cyclic twisting. Spiral Torsion Spring suits rotary mechanisms with tight radial dimensional limits. A Spiral Torsion Spring handles large-angle rotary reset for flat-profile mechanical housings.

Machinery assemblies requiring large rotation angles with constrained radial housing space adopt this spring. Electronic equipment and instruments install planar rotary reset hardware inside flat-profile housings. Furniture and toy mechanisms use it for smooth rotary rebound over wide movement ranges. Buyers need to specify rotation angle and target torque during requirement submission.

Buyers provide technical drawings or physical samples, with clear rotation-angle and torque specifications. Shengzhou Deyuxiang Hardware Accessories Co., Ltd. replies to incoming inquiries within 12 hours. Feasibility assessment and quotation finish within 3-5 working days. Sample production spans 10-30 working days. Bulk-production activates only after sample validation. Minimum order quantity equals 5000 pieces.

Inspection combines spot sampling and optional full inspection before packing. Operators verify spiral profile, rotation angle and torque consistency. Third-party inspection can be arranged. Planar coiling and heat-treatment maintain flat geometry and layer separation for each production batch. Export-grade packaging prevents spiral layer shifting during transit via individual unit shielding, secured inner boxes and labelled export cartons. Standard lead time 7-15 working days, custom lead time 15-30 working days. Repeat orders receive 3-10 working days advance scheduling. EXW and FOB support USD and RMB payment.
