Draht und Kabel
The wire and cable industry produces electrical, data, and structural conductors made from copper, aluminum, and specialty alloys. These products are essential for power distribution, telecommunications, automotive, aerospace, electronics, and construction. The focus is on conductivity, flexibility, durability, and in many cases, insulation integrity and surface quality.
Manufacturing requires high-speed, continuous production and tight control of physical and electrical properties, making induction heating an ideal solution for many critical steps.
How Induction Heating Supports Wire & Cable Manufacturing
Induction heating provides precise, localized, and energy-efficient heat, especially useful for inline and high-speed applications. It’s used for annealing, preheating, drying, curing, and coating preparation, enabling better material properties and cleaner processing.
