Custom Metal Coil & Spring Manufacturing Services
Since 1955, we've been providing the global OEM market with a variety of custom extension, compression and torsion springs for demanding commercial and industrial applications. Requirements for ground compression springs can be met by our full line of spring grinders for even the tightest tolerances. Along with the variety of springs we offer, we can also provide custom wireforms on the same CNC wire forming equipment. We can work with any wire material up to 0.312" thick in both round and square wire. Additional services include a complete spring grinding department to finish off your compression spring requirements.
We can fabricate springs based on your drawings, or assist you with the engineering at the concept stage. Our team will put its years of experience to work in making prudent recommendations to meet your specific application requirements. Our state-of-the-art CNC coilers use multi-axis robotic actuators, sensors, probes to ensure dimensional conformance and consistency.
