Hot Coil (or Hot Wound) Springs
MW Industries, Inc. offers both automated and manual hand coil capability in the manufacture of hot coil (or hot wound) springs. Our highly automated line can take many grades of high-alloy materials up to 1.875" in diameter and produce hot-coiled springs with outside diameters of 9.0" max and free lengths up to 39.0".
World class quality is achieved through state of the art heat-treating, shot peening, and automated load testing all while exceeding demanding fatigue requirements and specifications.
Various end configurations, grinding, coating, marking, and special packaging processes are designed to meet your special needs. Larger bar diameters of 2.25" and bar lengths of 27.0' can be hand coiled on smaller quantity demands offering the same quality requirements.
