INDUCTION HEATING DEVICE AND METHOD FOR MAKING PARTS USING SAME

摘要

The invention concerns a device for heating a surface by induction, in particular for molding or transforming a part made of thermoplastic or thermosetting composite material. The device comprises a body (16) having at least one portion (18) made of magnetic and heat conducting material wherein is provided a plurality of closed cavities proximate the surface (12) to be heated, each cavity surrounding a field winding (24). The heat produced by induction on the walls of the cavity is transferred by conduction to the heating surface. The distance between the cavities and the position of said cavities relative to the heating surface are such that the heating is substantially uniform on said surface.
