Abstract:
1. A molding device for the shaping of a material, said device comprising: a lower mold body, or die, made from an electrically conductive material and comprising a molding zone intended to be in contact with the material to be shaped; an upper mold body, or punch, made from an electrically conductive material, and comprising a molding zone intended to be in contact with the material to be shaped; a removable intermediate part, or core, made of an electrically conductive material, inserted between the die and the punch; and induction means capable of generating a magnetic field that surrounds the die, the punch and the core, the die, the punch and the core being electrically insulated in pairs, wherein a first air gap is delimited by a first face of the core and the molding zone of the die facing opposite the first face, and a second air gap is delimited by a second face of the core and the molding zone of the punch facing opposite the second face, said first and second air gaps formed such that the magnetic field flows therein and induces currents at respective surfaces of the molding zones of the die and the punch.
