Back in the late 1970’s a group of men came together to support the idea of the Cascade Machine. The Cascade Machine got a U.S. Patent approval on June 14, 1983. Becoming incorporated on 12/18/1980, the first Cascade Machine, as we know them today, was sold in 1986. Iowa Engineered Processes won the Iowa Govenor’s Export Award in 2001. Our machines have been sold on three continents, Europe, Asia and North American.

In July 2005, Iowa Engineered Processes started a second division that was devoted to custom fabrication. Iowa Engineered Processes provides contract services to companies that require manufactured parts from outside sources. Iowa Engineered Processes, Inc. specializes in custom manufacturing that requires metal breaking, welding, painting, CNC turning and milling.
