Abstract

A use of a feeder insert, having a volumetric center of gravity which is offset in relation to the opening axis of the passage opening of said feeder insert, in the manufacture of a casting mold having a vertical mold separation and a feeder insert which for dense feeding of the mold cavity during the casting procedure is attached to the casting mold, is described, wherein the feeder insert is positioned in a prefabricated mold part of the casting mold such that the opening axis of said feeder insert runs below the volumetric center of gravity of the latter.
