Great Lakes Castings, LLC has been producing high quality gray iron castings for over half a century. Founded in 1945 and in continuous operation since April 1946, Great Lakes Castings built a reputation as one of the nation's premier high production domestic foundries, and continues to do so today. We serve clients throughout the majority of the U.S., Mexico and Canada.

Our 160,000 square foot foundry is located on 26 acres in the city of Ludington, Michigan, and has had several significant expansions over the past few years allowing us to be an industry leader in technology, safety, andenvironmental Protection.

Great Lakes Castings is also one of the few high production domestic foundries to have a fully equipped laboratory capable of metallurgical, chemical, physical and material code specifications.

In fact, the GLC foundry contains an array of modern green sand molding equipment and we offer engineering services (in-house pattern shop, design and dimensional layouts) and other process capabilities including shell core, cold box, heat�treat capabilities, and of course, annealing.

One of our most significant expansions was a 26,500 square foot facility built to house a 2013B Disamatic molding machine. A finishing facility was established in Holland, Michigan in 2004. Our iron foundry produces quality ferrous and gray iron castings serving many different industries and applications. While GLC specializes in gray iron castings, our markets include Heating and Air Conditioning, Automotive Aftermarket, Compressors, Construction, Agriculture, Pumps, Refrigeration, and Valves.

Great Lakes Castings' original founders were Donald Birtwistle, Theodore Miller, Louis Rehbein, and Raymond Gilbert. The company was sold in February of 1984 to Brittany Corporation, an investment group located in Cleveland, Ohio and was acquired in December of 2006 by Republic Financial Corporation, a privately held investment company located in Aurora, Colorado. In 2013, Great Lakes Castings was sold to The Reserve Group located in Akron, OH.
