ABSTRACT:
The ceramic core is located within the ceramic mold by the insertion of recrystallized alumina pins through the wax encasing the core prior to encasing the whole in a ceramic slurry; on the subsequent removal of the wax, the molten metal, i.e. superalloy, is injected into the resulting space; the recrystallized alumina pins remain intact during the casting process hence substantially increasing the success rate of achieving accurate core locating during casting solidification.
