Coil Springs

Master Spring & Wire Form Co. manufactures custom precision coil springs (helical springs) with a wire diameter of 0.008” to 0.192” and with most material types: brass, bronze, copper, beryllium copper, carbon steel, hard drawn, inconel, music wire, oil tempered, phosphor bronze, and stainless steel. 

Compression Coil Springs: We manufacture all different shapes of compression coil springs such as straight cylindrical, conical, barrel, and hourglass.  These compression coil springs can be ground or not ground.  The pitch or spacing between the coils can be constant or variable.

Extension Coil Springs: We make extension coil springs with all types of ends, loops, or hooks such as twist loops, cross-center loops, side loops, extended hooks, swivel hooks, and flat stock hooks.

Torsion and Double Torsion Coil Springs: We manufacture torsion and double torsion coil springs with many different end configurations on the legs. 

Finishing: We take care of any finishing required on your coil springs, such as stress relieve, shot peen, plate, powder coat, passivate, electropolish, dye or paint, bake enamel, and plastic coat.  We can also assemble your coil springs into your mating part, or special pack your coil springs to prevent tangling.  If you wish to test your coil spring design with a rapid prototype, this is one of the engineering services that we offer.
