Abstract
The present disclosure generally relates to casting molds including a casting core comprising an outer shell mold surrounding at least a portion of a casting core and a casting core comprising a second metal skin layer around a first metal component. In one aspect, at least one portion of the first metal component may be exposed on a surface of the outer shell mold. In another aspect, the outer shell mold may be configured to define a cavity in the casting core when the first metal component is removed and the second metal skin layer is not removed.

A casting mold comprising:
- a casting core comprising a first metal component and a second metal skin layer surrounding at least a portion of the first metal component, the second metal skin layer having a higher melting point than the first metal,
- wherein the first metal component is configured such that upon removal a cavity is formed that may be filled with a third metal.
A method of making a cast component comprising:
- a casting core including a first metal component and a second metal skin layer surrounding at least a portion of the first metal component, the second metal skin layer having a higher melting point than the first metal;
- removing the first metal component to form a cavity within at least a portion of the second metal skin layer;
- and
- adding a third metal to fill at least a portion of the cavity within second metal skin layer
