Abstract

Die Erfindung bezieht sich auf eine Gießformkomponente mit einer permeablen Basisschicht (2) aus einem Basisschichtmaterial, welches eine zum Leiten von Flüssigkeit dimensionierte Basisschicht-Permeabilität (k2) aufweist, mit einer permeablen Filterschicht (1), welche eine Filterschicht-Permeabilität (k1) aufweist und welche sich von einer Oberfläche der Basisschicht (2) zu einem Gießraum (6) erstreckt, und mit einer Leitungseinrichtung (5, 7), die zum Ableiten von aus dem Gießraum (6) durch die Filterschicht (1) hindurch geströmter Flüssigkeit aus der Basissicht (2) und/oder zum Zuleiten eines Druckmediums in die Basisschicht (2) und durch die Filterschicht (1) zum Ablösen eines im Gießraum (6) gebildeten Scherben ausgebildet ist, wobei eine Abdichtungsschicht (8) von der Filterschicht (1) beanstandet an der Basisschicht (2) angeordnet ist, wobei die Abdichtungsschicht (8) eine Abdichtungsschicht-Permeabilität (k8) aufweist und wobei die Abdichtungsschicht-Permeabilität (k8) geringer ist als die Basisschicht-Permeabilität (k2) der Basisschicht (2).
