Stiefel Induction Heaters: Energy-Efficient Solutions Since 2013

Metal induction heater is a broad term encompassing the use of electromagnetic induction to heat electrically conductive materials, primarily metals. The process is non-contact and highly efficient, generating heat directly within the workpiece. This fundamental technology is applied across a vast spectrum of industries for purposes including but not limited to: heat treating (hardening, tempering, annealing), metal melting, brazing and soldering, forging, shrink-fitting, and crystal growing. The specific design of the induction heater—its power, frequency, and coil geometry—is determined by the material properties (such as resistivity and magnetic permeability) of the metal being heated, the size and shape of the part, and the desired outcome (e.g., surface hardening vs. through-heating). Ferrous metals like steel are generally easier to heat at lower frequencies due to their magnetic properties, while non-ferrous metals like aluminum and copper require higher frequencies. Stiefel Combustion offers a comprehensive portfolio of metal induction heaters, from standard models to fully customized turnkey systems, capable of processing virtually any metal component. Our expertise ensures optimal system selection for your specific material and application. For all your metal heating needs, we invite you to contact our team to explore the most effective solution.
