Abstract

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung eines gekühlten Gussteils (1) einer thermischen Turbomaschine mit einem bekannten Gussverfahren. Zwischen einem Wachsmodell (10) des Gussteils (1) und einem keramischen Kern (6) wird oberhalb einer Stufe (7) von Hand eine Wachdichtung (8) lediglich auf einem zusätzlichen Absatz (9) angebracht. Das Material, welches während des Giessverfahrens durch den Absatz (9) und die Wachsdichtung (8) an dieser Stelle entsteht, kann geschliffen werden, ohne dass sich Unebenheiten an der Stufe (7) bilden. Das Schweissen oder Löten einer Kühlplatte auf die Stufe (7) wird dadurch vereinfacht.
