Springs manufacturers
If you are searching for springs manufacturers, suppliers range from large catalog stock-spring producers to custom OEM spring shops that do coil, leaf, torsion and flat springs. Buyers should look for manufacturers that state they both produce (manufacture) springs and offer the specific processes you need (custom winding, material grades, heat treatment, volumes).

What to specify in your RFQ
Manufacturers quote faster and more accurately when your request covers these points.
- Spring type
Specify compression, extension, torsion, coil, leaf, flat or wire-form so the manufacturer can propose suitable tooling and processes.
- Material and any heat treatment
Provide the alloy/grade (e.g., stainless, music wire, oil-tempered) and required heat-treat or surface finish (plating, coating) for corrosion or fatigue life.
- Dimensions and tolerances
Give free/solid length, wire diameter, outer diameter, pitch, and critical tolerances that affect fit or function.
- Load and deflection requirements
State required loads at specified deflections, operating cycles, and maximum travel to ensure correct spring rate and life.
- Quantity and volume profile
List initial order quantity, expected annual volumes, and whether you need prototypes, low-volume runs or high-volume production.
- End form and attachment features
Describe hooks, loops, flattened ends, eyes, collars or other custom end forms and how the spring will be mounted.
- Standards and testing
Specify any industry standards, ISO/TS requirements, or testing (fatigue, load testing, dimensional inspection) required for acceptance.
