The Delmer Induction Heating System is a high-efficiency, non-contact heating solution designed to uniformly preheat steel, copper, aluminum, and other conductive wires before downstream manufacturing processes. Using advanced electromagnetic induction technology, the system delivers rapid and controlled heating directly within the wire, ensuring improved process consistency, enhanced product quality, and reduced energy consumption. Induction wire preheating is widely used before insulation extrusion, welding, annealing, coating, and forming operations.
Unlike conventional heating methods, induction heating generates heat within the material itself, providing faster response times, precise temperature control, and superior energy efficiency while eliminating direct contact with heating elements.
