Core (manufacturing) Wikipedia

 · When the corebox is opened and the core removed, the uncured sand inside the core is dumped out to be reused. This practice can also be observed in some cold-box coremaking practices, though cold box shell-core making is much less common. In a similar vein, the cold-box process uses a binder that is hardened through the use of special gases

Sand casting Wikipedia

 · In 1940, thermal sand reclamation was applied for molding and core sands. In 1952, the "D-process" was developed for making shell molds with fine, pre-coated sand. In 1953, the hotbox core sand process in which the cores are thermally cured was invented.

Core Making & Assembly – Heat Treat Process

 · The shell core process pre-coats the sand with a resin before pouring it into a pre-heated core box. Heat is applied to the surface until a thin, hard shell is formed. We use shell cores to reduce the bulk and mass of a core within a casting, or for castings that require tight dimensional controls and good surface finish.

For example, imagine making a cannon. The bore (hollow section) of the cannon can be formed by a core. The hardened sand core goes into the cannon mold so that the molten metal will form the cannon body, but be blocked from filling the center. After the metal cools, the sand core is shaken out of the cannon, leaving the hollow barrel.
