Special Shaped Springs
Special Shaped Springs for Custom OEM Assemblies
Special shaped springs cover non-standard coil, conical, tower, flat, touch or formed spring designs that need drawing-based review. Built for OEM buyers who need drawing review, material selection, inspection planning and a clear RFQ path.
Product and Engineering Review
Special shaped springs cover non-standard coil, conical, tower, flat, touch or formed spring designs that need drawing-based review.
| Spring type | Conical, tower, custom formed, touch spring, shaped wire spring or drawing-specific spring part. |
|---|---|
| Quote basis | Function, shape, material, critical dimensions, load or contact requirement, quantity and application. |
| Custom dimensions | Geometry is confirmed from CAD, sample or dimension sketch. |
| Materials | Carbon steel, stainless steel, music wire, phosphor bronze, brass and other project-specific materials for review. |
| Finish review | Surface finish, conductivity and corrosion needs should be included with the RFQ. |
| Testing | Dimensional, load, torque or fit checks can be planned according to the function. |
| Production route | Coiling, forming, stamping support, heat treatment, sorting and inspection planning. |
| Files | PDF, DWG, DXF, STEP, sample photos or a dimension sketch can start the RFQ review. |
| Published wire range | Supplier website company overview lists production wire diameter range as 0.1-4.0 mm; drawing-specific feasibility is still reviewed by spring type, material and geometry. |
| Tolerance basis | Tolerance is confirmed by drawing, critical dimensions, material and inspection requirements; no fixed public tolerance table is used for all custom spring designs. |
| Lead time basis | Quotation, sample timing and production delivery are confirmed after drawing, material, quantity and inspection requirements are reviewed. |
RFQ details that speed up review
- Drawing or sample photos with critical dimensions marked.
- Material, finish, quantity target and application environment.
- Load, torque, contact pressure or functional requirement if available.
- Inspection report, packing or batch documentation needs.
Manufacturing Review
- Review whether the spring function is load, contact, retention, torque or assembly spacing.
- Check manufacturability of complex bends, stacked coils or contact surfaces before tooling.
- Plan sample validation before moving into larger batch production.
Typical Applications
- Touch springs, special contacts and compact device assemblies.
- Locks, hardware, appliance and electronics mechanisms.
- Custom industrial products where catalog springs do not fit.
Quality Checks
- Critical dimensions, fit points and functional load/contact points can be checked.
- Project-specific inspection reports can be discussed during RFQ.
- Sample comparison can be used when drawings are incomplete.
Supplier-Published Manufacturing Basis
These figures are used as supplier-published capability references for RFQ screening. Final manufacturability, tolerance and delivery timing still depend on the drawing and order requirements.

Custom Spring Manufacturing Process
Each project is reviewed from the drawing, sample or application requirement before sampling and production planning.
Drawing Review
Confirm dimensions, function, material and missing RFQ details.
DFM Review
Check forming, coiling, springback, stress and assembly risks.
Sample Planning
Prepare sample route and inspection points for engineering review.
Production Setup
Plan coiling, forming, heat treatment, sorting and packing needs.
Inspection
Review dimensional, load, torque or functional checks by project.

Frequently Asked Questions
What information do you need to quote special shaped springs?
A drawing, sample photo or sketch is the best starting point. Please include material, wire diameter or thickness, critical dimensions, quantity, application and any load, torque, contact or inspection requirements.
Can you manufacture from a drawing or sample?
Yes. The RFQ can start from PDF, DWG, DXF, STEP files, sample photos or a dimension sketch. Missing details should be confirmed before sampling.
Which materials are available?
Common review options include carbon steel, stainless steel, music wire, phosphor bronze and brass, depending on the spring type and application requirements.
Can you provide load, torque or dimensional inspection?
Dimensional checks, load testing, torque checks and inspection reporting can be planned when the drawing or project requires them.
Do you support samples before production?
Sample review can be planned before larger production, especially when the part is custom, compact or function-critical.
What should be confirmed before mass production?
Confirm final drawing revision, material, finish, quantity, inspection standard, packing method and any application-specific risks before batch production.
