Chill (casting) - Wikipedia

A chill is an object used to promote solidification in a specific portion of a metal casting mold Normally the metal in the mould cools at a certain rate relative to thickness of the casting When the geometry of the molding cavity prevents directional solidification from occurring naturally, a chill can be strategically placed to help promote it There are two types of chills: internal and external chills
