Fairfield Castings, LLC is a versatile iron casting facility that is able to provide services to a diversified customer market. Gray and ductile iron castings are produced simultaneously in a range of production volumes from a variety of molding centers. Molding capabilities include squeezer and rotolift manual molding, automatic horizontal match-plate molding, and Disa vertical molding. Maximum flask sizes are 20" x 26" for automatic horizontal machines, 26" x 36" for manual horizontal machines, and 21" x 26" for Disa vertical machines. Casting weights typically range from 1 lb. to 100 lbs. Isocure and shell core making machines are capable of producing custom cores for a variety of volumes and applications.

The Fairfield Castings' engineering staff can provide manufacturability reviews and offer input on customer designs. Advanced mold flow and solidification simulation software allows feedback to designers on casting integrity prior to actual tooling fabrication and production. Our complete in-house sand lab monitors the compactibility, bond content, permeability, moisture, and green strength of the sand. Material testing including tensile testing, hardness testing, complete chemical analysis and microstructure inspection is available.

We serve a variety of industries including producers of motor vehicles, agricultural equipment, construction equipment, and other industrial components. For more information about our custom gray and ductile iron casting capabilities, see the table below, or contact us directly.
