Stiefel Induction Heaters: Energy-Efficient Solutions Since 2013

An induction heating machine for forging is used to heat metal billets, bars, or slabs to a precise, uniform temperature suitable for plastic deformation in a forge press or hammer. The primary goal is through-heating, where the entire cross-section of the material must reach the forging temperature (typically between 1100°C and 1250°C for steel) to ensure proper material flow without internal tearing or excessive scale formation. Induction heating is ideal for forging due to its speed, efficiency, and cleanliness compared to gas-fired furnaces. It provides consistent temperature control, resulting in improved die life, reduced scaling (and thus less material loss), and better metallurgical quality of the forged part. Stiefel Combustion's forging induction heaters are high-power systems designed for continuous operation in rugged environments. They can be configured as single-shot heaters for large parts or as longitudinal heaters for continuous feeding of bar stock into the forge. Our systems help forges increase production rates while lowering energy consumption and improving working conditions.
