Abstract
A composite core structure is used for metal casting in order to form cavities of preselected sizes and shapes within the casting. The composite core has an insoluble support member that can be metallic and a soluble portion disposed around at least a part of the support member. When the composite core is used in a casting process, such as a die casting process, the soluble portion is dissolved after the casting process is complete, and the insoluble portion is then removed from the cavity that was formed through the use of the composite core.
