Custom Stainless Steel Torsion Springs with 0.2-8mm Wire Diameter Precision CNC Manufactured

Our Custom Torsion Springs are engineered to deliver precise rotational force, excellent resilience, and long-lasting performance for demanding industrial applications. Manufactured from premium stainless steel, carbon steel, music wire, alloy steel, and other high-quality spring materials, these torsion springs are available in wire diameters ranging from 0.2 mm to 8.0 mm to meet diverse mechanical requirements.

Designed for both single and double torsion configurations, our springs provide reliable torque generation and angular deflection while maintaining exceptional fatigue resistance throughout millions of operating cycles. Every spring is manufactured using advanced CNC spring forming equipment, precision heat treatment, and strict quality control processes to ensure consistent dimensions, stable torque output, and outstanding durability.

As an experienced OEM & ODM torsion spring manufacturer, we support complete customization based on customer drawings, CAD files, samples, or performance requirements. Whether you need miniature precision torsion springs for electronic devices or heavy-duty torsion springs for industrial machinery, automotive systems, agricultural equipment, or medical devices, our engineering team can develop the optimal solution.

All products undergo comprehensive inspections including dimensional verification, load and torque testing, surface quality inspection, and material certification before shipment. Our manufacturing process complies with international quality standards, ensuring reliable performance even in high-load, high-cycle, corrosive, and extreme operating environments.

With flexible production capacity, rapid prototyping, competitive pricing, and global export experience, we provide high-quality custom torsion springs trusted by customers worldwide.
