The invention relates to a process for producing shaped metal parts, in particular reduced-weight shaped parts made from metallic materials. In this process, a metal body with a surface which is closed on all sides and a hollow structure in the interior is placed into a die as a core and is then surrounded with a metal melt by casting. The surface region of the metal body has a mean density which is higher than the interior of the metal body by a factor of 1.5 to 20.
La présente invention concerne un procédé de réalisation de pièces moulées métalliques, notamment de pièces moulées de poids limité en matériaux métalliques. Selon l'invention, un corps métallique ayant une surface fermée de tous côtés et une structure interne creuse, étant introduit dans un moule en tant que noyau, et rempli d'un métal en fusion. La partie superficielle du corps métallique a une densité moyenne supérieure d'un facteur 1,5 à 20 à celle de l'intérieur du corps métallique.
