Midwest Machining and Fabricating

In 1982, Midwest Machining and Fabricating was created to complement Arnette’s services and provide a wide range of machining, metal fabricating, machine building and machine rebuilding capabilities.

We provide custom machining and custom machine parts for any application. Our wide variety of machining equipment allows us to handle any project…from the simplest to the most complicated…regardless of size or quantity of parts. Tight tolerance machined products are the mainstay of our business, with extensive experience in steel-making and power transmission industries.

High-quality containment tanks, fixtures, and weldments are a specialty.

Our exclusive “strip and advise” machine rebuilding program is designed to protect our customers from the high costs which are often associated with T&M repair estimates.





Our History


Arnette Pattern Company, Inc., located in Granite City, Illinois, first opened its doors. At this time, Bill Zimmer was 18 years old and just beginning his first year of apprenticeship as a pattern maker.


Bill was joined by his son Gary, as he began his apprenticeship in the craft.


Bill and Gary assumed ownership of Arnette Pattern Company, Inc., and they were joined by two other sons, David and Paul, also apprentice pattern makers.


Midwest Machining and Fabricating was created to complement Arnette’s services to its customers.


Bill retired from his ownership responsibilities, and David and Paul assumed part ownership of Arnette-Midwest.


Arnette-Midwest’s commitment to continual improvement in customer service resulted in the construction of a new 30,000 square foot facility designed to serve as corporate headquarters, as well as the main location for Arnette-Midwest’s industrial pattern making, mold making, and machining departments.


In 2011 we began expansion of our main facility to accommodate growth in our machine building and machine re-building market segments. This 25,000 square foot addition provided space for numerous new machining centers, an updated fabrication area, and an expanded design/engineering department. Completed in early Spring, 2012, the extra capacity has also resulted in a 50% increase in the company’s overall workforce.


In April we leased an adjacent 12,500 square foot building to provide additional capacity for our growing machine building and machine re-building business sectors.
