Metal Forming Industries (MFI) is a specialized contract serial manufacturer founded in 1991 and located in Russellville, Indiana. Acquired in 2012 by Ron St. Clair’s St. Clair Group, MFI is an ISO 9001 certified, veteran-owned enterprise focused on precision metal forming and machining.
MFI specializes in cold forming, specialty cold heading, and deep impact extrusion of non-ferrous metals, particularly pure copper, aluminum, and brass. The company solves the high upfront tooling barrier typical of cold forming by using proprietary internal tool manufacturing and quick-change tooling setups.
This distinct tooling approach allows MFI to cost-effectively run cold-formed parts in production quantities as low as 1,000 pieces per year, delivering material savings of up to 70% and cycle time reductions of up to 50% compared to solid billet machining.
