More Information
Summary:A coating layer such as a paint coating, a sealer, or the like on an electrically conductive workpiece such as an automotive body is baked or dried by holding an induction coil or induction coils closely to the workpiece, supplying an electric current to the induction coil or coils to induce eddy currents in the workpiece to heat the workpiece with the eddy current, and applying a gas such as air to the surface of the coating layer to bake or dry the same.
