State Line Foundries is a jobbing iron casting facility based in northern Illinois, operating two foundries located about five miles apart to produce a range of gray and ductile iron parts, with castings weighing up to 2,500 pounds. The company also pours specialty alloys, including austempered ductile iron and high silicon moly, and serves customer-specific alloy requirements. Its primary focus is prototypes and low-to-medium volume production, including replacement and service parts, and it works with clients to address time-critical delivery, tooling adjustments for smaller runs, design-for-manufacturability reviews, and certification needs through in-house laboratory capabilities. Positioned within the mining industry, State Line Foundries emphasizes its ability to act as a bridge production foundry for customers preparing to transition to their own production facilities. The firm is based in Roscoe, Illinois, and operates with a lean workforce to provide technical expertise, combined processes, and timely quality castings.
