About UsAbout Us


Over the last 50 years Criterion Manufacturing has experienced several changes, but one thing still remains the same, We have a passion for manufacturing and the various industries it serves.

Criterion started in a basement in Finchford Iowa in 1972 as a manual machine shop doing repairs for local businesses and neighbors. Today we still serve local businesses along with customers around the world. In 2016 we moved into our current location. We have 50,000 square feet of manufacturing floor space under one roof with plenty of room for additional expansion. We are conveniently located off US Highway 218 on the North side of Waterloo near the airport.

We are capable of running short or long production, reverse engineering/prototyping, or repairing existing assemblies. We are capable of machining or fabricating most any type of material, from solid bar stock, castings, weldments and anything in between.
