ABSTRACT:
To prevent movement of a ceramic core in a ceramic shell for the investment casting of a turbine blade, the free end of the core has one or more pins embedded therein so that the pins project into both the core and the ceramic shell which is applied over a wax layer. After removal of the wax and firing of the shell, molten metal is cast in the space left by the wax between the core and the shell. After hardening of the metal, the outwardly projecting part of the pins are removed during the machining of the surfaces of the turbine blade blank.
