Using Inductotherm and Brown Boveri melting furnaces each capable of up to two tons per hour, Specialty Castings pours gray and ductile iron castings ranging from 1/4 lb to 250 lbs. The Hartley controlled green sand molding system provides for a broad range of casting sizes and configurations using matchplate, squeezer, and cope and drag pattern types.
The core making capabilities include wood, metal, or plastic core box air set on a double head Harrison shell core machine. Finishing is applied to each casting using a wheelabrator blast unit, grinding stations, and didion drum.
