The invention relates to a method for casting moulded parts, said method comprising the following steps: the mould is prepared by forming a core packet from the cores which are made of moulding sand; the metal melt is cast into the mould; the mould is subjected to thermal insulation prior to and/or after casting and the thermal process is used in a known manner inside the mould and/or insulation for controlled treatment of the casted moulded part and/or the moulded material forming the core packet.
L'invention concerne un procédé de coulée de pièces moulées, ce procédé comprenant les étapes suivantes : préparation du moule, constitué de noyaux en sable de coulée regroupés sous la forme d'un ensemble de noyaux, coulée du métal en fusion dans le moule, isolation thermique du moule avant et/ou après la coulée et utilisation réfléchie de la chaleur de processus à l'intérieur du moule ou de l'isolation pour traiter de façon contrôlée la pièce moulée par coulée et/ou la matière du moule formant l'ensemble de noyaux.
