    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

  • Manufacturing Process of Cast Iron Castings

    Cast iron begins its life as pig iron which is remelted and often combined with large amounts of scrap iron and sometimes with steel. Contaminants are removed from the melted pig iron and the iron once melted is then cast. Casting is the process of pouring the iron into a mold thus giving it a shape.
