Springs manufacturers

Springs manufacturers range from specialty custom spring shops (coil, torsion, compression, extension, wire forms) to large OEM producers and catalog/stock-spring suppliers. Buyers should decide whether they need custom tooling and tight tolerances, stock/catalog items, material/finish options, or industry certifications before contacting suppliers.

What to specify in your RFQ

Manufacturers quote faster and more accurately when your request covers these points.

  • Spring type

    Compression, extension, torsion, leaf, wire form, or specialty — different makers specialize in different types.

  • Wire/material grade

    Specify alloy (music wire, stainless, chrome silicon, etc.) and heat treatment or corrosion-resistant finishes required.

  • Dimensional specs

    Wire diameter, free and solid height (for compression), coil diameter, number of coils, leg/arm geometry for wire forms.

  • Tolerances & performance

    Deflection/load at specified gaps, squared/ground ends, and allowable dimensional and spring-rate tolerances.

  • Quantity / annual volume

    State prototype qty and production/annual volumes to determine tooling, lot pricing, and lead times.

  • Surface finish / coating

    Zinc, phosphate, plating, passivation, or painting requirements affect supplier choice and cost.

  • Testing / certifications

    Specify required testing (load testing, fatigue life) and certifications (ISO, automotive standards) upfront.

Sourcing FAQ

How do I evaluate a spring manufacturer?
Ask for examples of similar parts, process capabilities (CNC coiling, wire forming), material traceability, testing equipment, and references; review lead times and sample policies.
What are typical MOQs for custom springs?
MOQs vary widely: some custom shops will run small prototype lots, while production runs may require hundreds to thousands depending on tooling and setup—confirm with each supplier.
Which certifications are relevant for springs?
Commonly requested items are ISO quality systems and material test certificates; automotive or aerospace buyers may require IATF/AS or NADCAP-related approvals depending on the application.
What drives lead time for spring orders?
Lead time is driven by complexity (custom tooling, bends), material availability, required testing, and current shop load; stock/catalog springs are typically fastest to ship.
