A method of manufacturing a heat shield panel assembly is provided. The method comprising: injecting melted wax into a negative cavity of a heat shield panel, the heat shield panel comprising one or more orifices; allowing the wax to solidify to form a positive pattern of the heat shield panel; removing the positive pattern from the negative cavity; coating the positive pattern with a ceramic; melting the positive pattern away from the ceramic, the ceramic having a cavity forming a second negative cavity of the heat shield panel; pouring melted metal into the cavity; allowing metal in the cavity to solidify to form the heat shield panel; and removing the ceramic from the heat shield panel.
