Conical Shaped Compression Springs are specially designed to ensure that each active coil fits within the next coil, so the solid height can be equal to one or two thicknesses of wire. These Springs have an increasing force rate instead of a constant force rate [regular compression springs]. JMD Springs is an ISO 9001:2008 awarded company that manufactures Conical Shaped Compression Springs.
JMD Springs offers multiple ranges of compression springs, extension springs, wire forms, brake springs, torsion springs, clutch plate springs, wave springs, volute springs, spiral torsion springs and spring bushes. Conical Shaped Compression Springs have a constant uniform pitch and an increasing natural period of vibration [instead of a constant] as each coil bottoms.
