Abstract
An induction heating device for manufacturing a part by heating the part to a predetermined temperature. The induction heating device includes an induction coil connected to an electrical power supply for generating an electromagnetic flux field. A smart susceptor of the heating device is positioned in the electromagnetic flux field and includes a magnetically permeable material supported by a mesh structure. The magnetically permeable material generates heat in response to the flux field. The mesh structure provides support for the magnetically permeable material and closely conforms to the desired outer geometry of the part. The magnetically permeable material may be applied as a powder to the mesh using a hot spray gun, allowing tight conformance of the susceptor to the part geometry while avoiding forming limits of sheet metal susceptors.
