Located in the heart of the Midwest, our foundry specializes in providing small to medium runs of brass and aluminum alloys especially for customer's needing quick turnaround and/or temporary services. Operating as a green sand, matchplate molder since the 1880's, customers include other manufacturers and foundries seeking more capacity, working through a relocation, expansion, and even those experiencing an emergency, natural disaster or other type of crisis.

We are dedicated to meeting all quality and delivery obligations as an original source supplier with full respect to restoring original source goodwill and business relationships after the need for our services has ended.

With direct access to machining and even assembly capability, we are able to accommodate a wide variety of situations.
