What We Do

Large Iron Casting

On-site. We specialize in large iron casting in the 500lb - 20,000lb range. 

Our Minster, OH location is capable of casting gray and ductile iron up to 45,000lbs.

Pattern Making

On-site. Patterns ultimately determine the shape and dimensional accuracy of the casting and contribute to iron integrity.

Machining

On-site. We simplify the casting process by providing castings machined on-site and sourced through our trusted supplier partners.
