Renton Coil Spring Company is a world-class spring manufacturer for the aerospace, military, industrial, and motorsport markets, providing superior quality parts and performance since 1949.
Design and material capabilities, along with complete performance solutions has led RCS to become a top supplier of quality springs, wire forms, assemblies, and flat metal parts with thousands of applications across the globe and beyond.
RCS can design and manufacture compression springs from 0.008" up to 1.375" diameter wire and bar stock. Round, square and rectangular cross sections are available for compression springs.
We are able to design and build extension springs from 0.015" to 0.630" diameter wire. Infinite hook variations are manufactured as well as extension assemblies with coned or threaded terminals.
RCS is capable of designing and producing torsion springs from 0.015" to 0.625" diameter wire and bar stock. Round, square and rectangular cross sections are available as well as tapered or multiple diameter springs.
Typically clock springs provide much greater rotational deflection than standard torsion springs. We design and manufacture clock springs from 0.005" up to 0.200" thick materials. These springs are also known as spiral torsion or hair springs.
For high load applications with a small installation space, RCS can design and build custom belleville or wave washers.
In the aircraft and automotive industries, these are used as vibration-damping elements because of their extremely detailed tuning ability.
Renton Coil Spring can create wire forms from 0.025" up to 0.250" diameter wire and bar stock. Also we design, manufacture and assemble components into assemblies or subassemblies such as spring loaded canisters, reels and other devices.
Our progressive tooling designs allow us to produce complex, close tolerance flat parts in an economical timely manner. Our in house stamping capacity is 50 tons. We design and manufacture close tolerance flat springs from 0.003" up to 0.125" thick and from 0.050" to several inches wide.
