A core is a device used in casting and molding processes to produce internal cavities and re-entrant angles. The core is normally a disposable item that is destroyed to get it out of the piece.
Cores are useful for features that cannot tolerate draft or to provide detail that cannot otherwise be integrated into a core-less casting or mold.
