Zusammenfassung:	The invention relates to an extrusion press for producing flat sheets from hollow sections consisting of magnesium or magnesium alloys, said press comprising a mandrel head that protrudes into the impression die opening of an extrusion die, the mandrel (5) being arranged with its mandrel head (7) protruding into the opening of the impression die and said mandrel head being (7) conical. L'invention concerne une extrudeuse servant à fabriquer des tôles planes à partir de profilés creux en magnésium ou en alliage de magnésium au moyen d'une tête de mandrin qui pénètre dans l'orifice de filière d'un outil d'extrusion. Le mandrin (5) est disposé de telle façon que sa tête (7) pénètre dans l'orifice de la filière depuis l'extérieur et la tête de mandrin (7) a la forme d'un cône.
