As the iron travels down the molding line, the temperature gradually decreases from about 2,600 to 1,200 degrees. As the iron castings cool, they enter a shakeout process in which the molds are shaken off and the sand is recycled for reuse. When our gray iron and ductile iron castings get below about 140 degrees, they are cleaned and finished.
