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 ...
