Torsion Springs

At Spring World Factory Co., innovation and precision drive the development of torsion springs that deliver controlled torque and smooth rotational performance. Our springs are designed for excellent stability, accuracy, and endurance, whether used in fine mechanical devices or heavy-duty industrial systems.

Applications

Torsion springs are widely used across mechanical and industrial systems, including:

• Door & Window Systems: Garage doors, shutters, and industrial hinges.

• Agricultural: Seeders, harvesters, balers, and irrigation systems.

• Lifting Mechanisms: Cranes, hoists, and balanced torque devices.

• Automotive: Door locks, hood mechanisms, seats, and transmissions.

• Precision Devices: Medical instruments, lab tools, and electronics.

• Miniature: Jewelry clasps, micro-locks, and small mechanical systems.

Material & Technical Specifications

• Materials: Carbon steel (Music Wire, Hard Drawn), Alloy steel (Chrome Silicon/Vanadium), Stainless steel (302, 304, 316), Nickel alloys (Inconel, Monel), and Copper alloys.

• Wire Diameter: 0.2 mm up to 17 mm.

• Spring Design: Single or double torsion. End forms include straight offset, loops, short hooks, hinge ends, and special ends.

• Performance: Precise torque control, high fatigue resistance, and stable operation.

• Surface Protection: Powder coating, electrophoretic coating, galvanizing, and corrosion-resistant finishes.

Quality Assurance

• Rigorous inspection of raw materials with full traceability.

• Continuous monitoring of torque–angle characteristics and end alignment.

• Compliance with international torsion spring standards.

• Ongoing quality improvement ensures long-term performance.

Heat Treatment & Surface Finishing

• Precision-controlled heat treatment for enhanced strength and dimensional stability.

• Shot peening for improved fatigue life.

• Advanced coatings: Powder coating, electrophoretic coating, galvanizing, and zinc plating.

• Custom corrosion-resistant finishes available upon request.
