Custom Torsion Spring Manufacturer

Pengsheng manufactures custom torsion springs based on drawings, samples, photos, sketches, or written specifications. Torsion spring review usually depends on leg geometry, rotation direction, installation space, torque or load requirement, and working environment.

Related sourcing terms covered: custom torsion springs, custom torsion spring manufacturer, torsion spring supplier, torsion spring factory China, precision torsion springs, double torsion spring manufacturer, torsion spring with custom legs, torsion spring prototype.

Custom Torsion Springs Made to Drawing or Sample

Manufacturability and quotation depend on leg geometry, material, quantity, tooling needs, and application review. A drawing is useful, but a sample, sketch, clear photo, or written specification can start the first review. For the broader workflow, see custom springs based on drawings or samples.

Single and Double Torsion Spring Considerations

Single torsion springs use one coil body with legs or arms that apply rotational force around the spring axis. Double torsion springs use two coil bodies connected by a center section and are reviewed when the assembly needs balanced or mirrored rotational action. Selection depends on mounting structure, rotation direction, torque requirement, leg position, and available assembly space.

Leg Geometry and Installation Requirements

• Leg angle
• Leg length
• Leg shape
• Arm orientation
• Rotation direction
• Inside diameter or outside diameter
• Wire diameter
• Number of coils
• Working angle
• Torque or load requirement
• Installation space

Materials and Finishing Options

Stainless steel, carbon steel, music wire, spring steel, and other material options can be reviewed according to working environment, force requirement, corrosion exposure, and drawing specification. Surface finishing such as plating, passivation, coating, polishing, or other options should be confirmed after drawing and application review. Exact grade, availability, and process route are not assumed before RFQ review.

Prototype and Sample Review Workflow

1. RFQ input review
2. Geometry and installation review
3. Quotation
4. Prototype or sample
5. Sample approval
6. Repeat production
7. Inspection
8. Shipment

Lead time and process route depend on geometry, material, finish, quantity, tooling needs, and inspection requirements. They are confirmed after review.

Torsion Spring Quality Checks

Checks can include dimensional inspection for coil body and leg geometry, leg orientation check against drawing or sample, visual inspection, load or torque-related check when required, sample approval before repeat production, and batch inspection records based on order requirements.

FAQ

What leg details are needed for a torsion spring quote?

Useful leg details include leg angle, leg length, leg shape, arm orientation, rotation direction, working angle, installation space, and the torque or load requirement.

Can you manufacture double torsion springs?

Double torsion spring requests can be reviewed when the drawing, sample, or application shows the center section, coil direction, leg geometry, and installation structure. Feasibility is confirmed after review.

Can you quote from a broken or existing sample?

Yes. An existing or broken sample can start the review if key dimensions and installation direction can be checked. Photos, sketches, and application notes can help clarify missing details.

What materials are suitable for torsion springs?

Common material options such as stainless steel, carbon steel, music wire, and spring steel can be reviewed based on working environment, corrosion exposure, force requirement, and drawing specification.

What should I include in a torsion spring drawing?

Include wire diameter, inside or outside diameter, number of coils, coil direction, leg geometry, working angle, torque or load requirement, material, finish, quantity, and installation notes.

Can you review a torsion spring from a photo or sketch?

Yes. A photo or sketch can start the first review, especially when the leg shape and installation direction are visible. Final quotation may still require dimensions, material, quantity, and application details.
