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 having at least one portion made of magnetic and heating conducting material wherein is provided a plurality of closed cavities proximate the surface to be heated, each cavity surrounding a field winding. 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.
The present invention concerns a device for molding of thermoplastic matrix composite materials or thermosetting materials. Two mold casings that are mobile relative to each other, electrically conductive material include a molding zone designed to be in contact with the material to be transformed, and an induction circuit for generating a magnetic field.
