Abstract (en)
In the castings of a turbine element, a sheet casting core (180) is assembled to a feedcore (182). The sheet casting core (180) and feedcore (182) are placed in a die (210,212,214). A sacrificial pattern material is molded over the sheet casting core (180) and feedcore (182) to form a pattern including an airfoil. The sheet casting core (180) extends from at or adjacent a trailing edge of the airfoil. The sheet casting core (180) has a first array of open areas and a second array of portions interspersed with the open areas. A first portion of the die (210) has a third array of projections contacting the second array.
