Throttle or lever return systems
Share the actual assembly or motion condition in the RFQ so feasibility review can focus on the working requirement instead of only generic dimensions.
Product Brief
Supplier-facing product scope with RFQ-ready context.
Used for discussing rotational force targets, leg angles, and packaging methods for return torsion spring parts.
- Family: Torsion Spring
- Material Range: High carbon or alloy wire based on torque need, Corrosion-aware finish for exposed use
- Application Fit: A return-force torsion spring for reset, lever, and control mechanisms that need predictable torque within a compact envelope.
- RFQ Suitability: Fits RFQs that show working angle, leg position, reset torque, and assembly constraints.

Manufacturing Notes
Process points that typically affect quotation and sample planning.
CNC torsion winding with direction control
The earlier these process assumptions are visible in the RFQ, the fewer rework loops are needed between engineering review and quotation.
Stress-relief and tempering for torque retention
The earlier these process assumptions are visible in the RFQ, the fewer rework loops are needed between engineering review and quotation.
Sampling for angle and torque verification
The earlier these process assumptions are visible in the RFQ, the fewer rework loops are needed between engineering review and quotation.
Packing method that preserves leg geometry
The earlier these process assumptions are visible in the RFQ, the fewer rework loops are needed between engineering review and quotation.
Inspection Focus
What the supplier review usually needs to confirm before release.
- Torque at working angle
- Angular repeatability
- Leg dimensions and coil body size
- Visual inspection after heat treatment
RFQ Checklist
Include these items to shorten clarification rounds.
Drawing with return-angle definition
Adding this information up front improves quote quality and helps route the request to the right production review path.
Installed torque or force target
Adding this information up front improves quote quality and helps route the request to the right production review path.
Direction and leg clocking
Adding this information up front improves quote quality and helps route the request to the right production review path.
Expected life cycle or environment
Adding this information up front improves quote quality and helps route the request to the right production review path.
Buyer Note
Clarify the working condition, not only the nominal shape.
Return torsion springs quote more accurately when the real installed angle is given, because torque at free state and torque in use can differ significantly.
