Custom 304 helical torsion spring
,Double arm rotational return spring
,Straight arm torsion spring 1.0mm
This helical torsion spring is precision‑formed by automatic spring coiling machines with 304 stainless steel spring wire. After coil winding and force‑arm bending, the part goes through heat‑treatment tempering for stress relief and shape stabilization, followed by careful deburring and strict torque & dimension testing.
Designed with dual straight force arms, this rotational return torsion spring generates consistent restoring torque under angular deflection. The 304 stainless steel material provides excellent rust resistance, fatigue resistance and long service life under repeated cyclic rotation.
We are a reliable custom torsion spring manufacturer. Beyond standard sizes, we deliver fully personalized OEM solutions including custom wire diameter, coil count, outer diameter, arm length, torque value and surface finishing to match unique mechanical reset and rotational clamping requirements for industrial assemblies.

We are a professional OEM manufacturer for custom torsion springs. Our custom service supports custom wire gauge, coil diameter, number of turns, force‑arm shape & length, torsion angle, torque rating and surface treatment. You can send us 2D drawings, 3D files or physical samples. We accept prototype samples, small‑batch trial orders and high‑volume mass production for your helical torsion spring projects.
- Precision tempering treatment reduces spring fatigue failure under frequent cyclic rotation
- 304 stainless steel raw material prevents rust and oxidation in humid working environments
- Strict torque calibration avoids inconsistent rebound force that causes unstable mechanical reset
- Smooth deburred surface eliminates scratch risk to mating plastic or metal components
- Flexible custom service solves the problem that standard off‑the‑shelf springs cannot fit special mounting dimensions
- Raw material certification inspection for 304 stainless steel wire before production
- In‑line dimensional check for coil diameter, wire size and arm geometry during coiling
- Torque force testing to verify rebound performance after heat tempering
- Full visual deburr inspection to remove sharp edges
- First‑article approval for every OEM custom order before mass production; inspection reports available upon request
Custom sample lead time: 3‑7 working days after drawing confirmation. Mass production lead time ranges from 7‑14 working days depending on order quantity. Multiple delivery options are available including international express, air freight and sea freight. Secure anti‑scratch packaging protects the finished custom torsion springs during worldwide transit.
- Can I order a custom torsion spring according to my drawing or sample?
- What tolerance can you guarantee for these stainless steel torsion springs?
- Do you support small‑batch prototype orders for testing?
- What alternative spring materials can you produce besides 304 stainless steel?
- How fast can I receive a formal quotation for my custom spring project?
Yes, we provide complete OEM custom service and manufacture helical torsion springs strictly following your specifications.
Our standard dimensional tolerance reaches ±0.05 mm, and tighter precision is acceptable for special industrial requirements.
We support sample runs, low‑volume trials and large‑scale mass production for all custom spring projects.
We also supply music wire, 316 stainless steel and carbon steel springs with different surface finishes on request.
We will prepare and send you a detailed quote within 24 working hours after receiving your design files or sample information.
