Abstract

A method of manufacturing a heat shield panel assembly (401) is provided. The method comprising: injecting melted wax (464) into a negative cavity (466) of a heat shield panel, the heat shield panel comprising one or more orifices (440); allowing the wax to solidify to form a positive pattern (468) of the heat shield panel; removing the positive pattern from the negative cavity; coating the positive pattern with a ceramic (470); melting the positive pattern away from the ceramic, the ceramic having a cavity (472) forming a second negative cavity (474) of the heat shield panel; pouring melted metal (476) 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.
