Compression Springs
Custom Compression Springs for OEM Applications
Compression springs are reviewed around working height, load requirement, wire diameter, outside diameter, free length, end configuration and assembly environment. Built for OEM buyers who need drawing review, material selection, inspection planning and a clear RFQ path.
Product and Engineering Review
Compression springs are reviewed around working height, load requirement, wire diameter, outside diameter, free length, end configuration and assembly environment.
| Spring type | Straight, conical or project-specific compression spring designs reviewed from drawing or sample. |
|---|---|
| Quote basis | Load, working height, free length, outside diameter, wire diameter, end type, material and quantity. |
| Custom dimensions | Dimensions are confirmed by drawing, sample or application space instead of a fixed catalog range. |
| Materials | Carbon steel, stainless steel, music wire, phosphor bronze and project-specific alloy options for review. |
| Finish review | Surface finish or plating requirements can be checked against material and application needs. |
| Testing | Dimensional inspection and load testing can be planned when the project requires report support. |
| Production route | CNC coiling, heat treatment, sorting, packing and inspection planning. |
| Files | PDF, DWG, DXF, STEP, sample photos or a dimension sketch can start the RFQ review. |
| Production wire range | 0.1-4.0 mm production wire diameter range for project screening; 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 because custom spring designs vary by geometry and function. |
| 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 spring rate, solid height risk, end configuration and assembly space before sampling.
- Plan CNC coiling setup around wire diameter, outside diameter, free length and end requirements.
- Confirm heat treatment, surface finish and packing requirements against the drawing.
Typical Applications
- Industrial equipment return and cushioning assemblies.
- Consumer electronics, smart appliances and hardware components.
- Valve, control, fixture and small mechanism projects.
Quality Checks
- Wire diameter, outside diameter, free length and perpendicularity checks where required.
- Load at specified working height can be tested and documented by project.
- Inspection reports can be discussed during RFQ.
Manufacturing Capability Basis
These capability figures support early 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 custom compression 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.
