304 Single Arm Torsion Spring Miniature Custom Torsion Spring for Precision

Product Description

Our 304 stainless steel single arm torsion spring is a precision miniature torsion spring produced by professional CNC spring forming equipment. The spring adopts 304 stainless steel spring wire, with natural bright stainless steel surface without electroplating treatment, delivering excellent rust resistance and corrosion resistance. The production workflow includes CNC coiling of spring body, single torsion arm bending forming, deburring, stress relief tempering for shape stabilization, then dimensional and elastic force testing & sorting. As an experienced torsion spring manufacturer, we provide custom & OEM service. We can adjust wire diameter, coil turns, outer diameter, leg length and torque according to your drawings or physical samples to match your specific mechanical assembly requirements. This single arm torsion spring provides stable rotational torque for repeated cycling movement in small precision assemblies.

Custom & OEM Service

We are a professional spring manufacturer providing full custom & OEM service for single arm torsion springs. You can send us your technical drawings or physical samples. We support customization on wire diameter, coil count, outer diameter, torsion arm shape & length, torque value and surface treatment. Our engineering team reviews your requirement and provides prototype samples before mass production to verify performance.

Key Advantages

1. 304 stainless steel material avoids rust and corrosion issues for long service life in humid environments
2. CNC precision forming ensures tight dimensional tolerance, prevents assembly fitting failure
3. Stress relief tempering process reduces spring fatigue, avoids torque loss after repeated use
4. Custom torsion arm geometry and torque to match your unique mechanism requirements
5. 100% inspection before shipment to reject defective products and reduce your assembly downtime

Quality Control

All single arm torsion springs go through multi-stage quality control. Raw material inspection of 304 stainless steel wire; in-process dimensional check during CNC forming; stress relief tempering process control; finished product testing including dimension measurement and torsion force verification. Defective items will be sorted out strictly. We can provide inspection reports upon request for custom orders.
