A component is formed from a component material introduced into a mold assembly. The mold assembly includes a mold that has a cavity defined therein by an interior wall. The cavity receives the component material in a molten state to form the component. A multiple component core assembly is positioned with respect to the mold and has a first core component attached to a second core component at a core split line. A core connection component is attached to each of the first and second core components at the core split line, such that the first core component is held adjacent the second core component at the core split line. The core connection component is formed from a connection component material that is at least partially absorbable by the component material.
