Main Foundry Plants
The round grain and high purity sand of Ottawa, IL makes it the most desirable molding and core-making medium for all size castings and most metals. Ottawa produces twenty-three standard foundry grades.
The operation produces coarse, medium and fine grades that are ideal for lost foam processes and other applications requiring the combination of high permeability and low fines.
The U.S. Silica plants located in Mill Creek, OK and Pacific, MO offer round grain sand grades that are excellent choices for molding and core making applications – all size castings and most metals. The unique nature of Mill Creek’s raw material and their advanced processing system is matchless in tensile strength when combined with a quality resin system. The round to sub-round grains of Pacific, MO products are similar in performance to the Illinois District sands.
Mauricetown, NJ and Hurtsboro, AL locations offer sub-angular sand grades that provide first class core strength, superior permeability and lower packing densities. These grades will allow expansion and contraction during your casting process with less potential for thermal cracking and veining.
The processes used at the Mauricetown, NJ and Hurtsboro, AL plants ensure consistent clean sand with low turbidities and increased tensile strength.
Let us help you to compete in the global market that demands quality castings!
