Core making is the process which forms the interior part of the casting. The mould provides a space for the molten metal to go, while the core keeps the metal from filling the entire space.

Core (manufacturing) - Wikipedia

A core is a device used in casting and moulding processes to produce internal cavities and reentrant angles (an interior angle that is greater than 180°). The core is normally a disposable item that is destroyed to get it out of the piece. [1]
