• Shot Peening on Compression springs, Extension Springs, Torsion Springs, Magazine Springs, Draw Bar Springs, Flat Springs, Wire Forms. Shot peening is a cold working process used to produce a compressive residual stress layer and modify mechanical properties of metals. It entails impacting a surface with shot (round metallic, glass, or ceramic particles) with force sufficient to create plastic deformation plastic deformation.

• Passivation of Compression springs, Extension Springs, Torsion Springs, Magazine Springs, Draw Bar Springs, Flat Springs, Wire Forms. Passivation is the removal of exogenous iron or iron compounds from the surface of stainless steel by means of a chemical dissolution, most typically by a treatment with an acid solution that will remove the surface contamination, but will not significantly affect the stainless steel itself. The iron or iron compounds that are found on the Stainless are from the machining or forming process of the spring or wire.

Materials used for Manufacturing Springs and Wire Forms:
Our Compression, Extension, Torsion, Double Torsion, Draw Bar, and Flat Springs are made from a variety of materials. Shaped Wire can also be utilized in the manufacture of springs, although they are usually at a cost premium. The materials we typically manufacture our springs and wire forms from are:
     • Music Spring Wire
     • Galv Music Spring Wire
     • Hard Drawn Spring Wire
     • Galv Hard Drawn Spring Wire
     • Oil Tempered Spring Wire
     • Stainless Steel Spring Wire
     • Beryllium Copper Spring Wire
     • Brass Spring Wire
     • Chrome Silicon Spring Wire
     • Chrome Vanadium Spring Wire
     • Phos Bronze Spring Wire

What is the 'Action' of the springs we manufacture?

Compression Spring: The action of the compression spring is to Push. With Compression Springs, wide load and deflection range can be achieved. The Compression Springs a constant or variable rate can be achieved.

Extension Spring: The action of the Extension Spring is to Pull. With Extension Springs there are a wide load and deflection range that can be achieved; the extension spring has a constant rate.

Torsion Spring: The action of the Torsion Spring is to Twist. With Torsion Springs a constant rate is achieved.

Magazine Spring: The action of a Magazine Spring is to Push. With Magazines Springs a wide load and deflection range is achieved. With Magazine Springs a constant or variable rate can be achieved.

Double Torsion Spring: The action of the Double Torsion is to Twist. With Double Torsion Springs the rate is equal to the sum of rates for each component.

Drawbar Spring: The action of the Draw Bar Spring is to Pull. The Draw Bar Spring is an extension spring with a solid stop. ie: Pool Cover Springs
