Power Spring

Power Spring consists of elastic steel band coiled into a spiral shape. Winding the band stores rotational energy. Released energy generates steady rotary force for retracting moving components. Heat-treatment slows torque drop after repeated winding and unwinding cycles. Power Spring delivers sustained rotary force instead of quick snap-back motion seen with many torsion-type components. A Power Spring provides smooth rotary actuation for retraction-focused mechanical assemblies.

Reciprocating mechanical assemblies utilise its smooth retraction for controlled rotary movement. Automotive and electronic device sub-components rely on automatic retraction and steady tension holding. Medical instruments, fitness gear and furniture hardware implement consistent rotary rebound for repeated actuation. Design documents should define maximum winding cycles and target torque value.

Shengzhou Deyuxiang Hardware Accessories Co., Ltd. collects torque value, rotation cycles and retraction mode information from project inputs. Technical staff respond within 12 hours. Feasibility evaluation and quotation complete in 3-5 working days. Sample lead time runs 10-30 working days before bulk-order launch. OEM and ODM services are supported. Minimum order quantity is 5000 pieces. Production photos or video can be shared per buyer request.

Quality control includes random sampling and optional full inspection prior to packing. Technicians measure torque magnitude, rotation range and retraction smoothness. Third-party inspection requests get approval. Coiling and heat-treatment workflows receive oversight to prevent slipping during cyclic operation. Export packaging stops loose band tangling through individual shielding, secured inner boxes and labelled export cartons. Standard product lead time 7-15 working days, custom product lead time 15-30 working days. Repeat orders get 3-10 working days priority scheduling. EXW and FOB accept USD and RMB settlement.
