BIG Changes at HMMI 

Originally incorporated on December 4, 1997, as Horizontal Machining, HMI was a small machine shop with two machines and a crew of five that helped the Midwest manufacturing community with production overflow and smaller machining operations. However, it didn’t take long for the original owner, Earl Nordby, to recognize a growing trend—OEMs wanted to outsource their fabrication, not just their machining. In addition, diverse industries were demanding larger, stronger, more robust requirements. To meet these needs, substantial growth became necessary.

2005 was a huge year that launched our current success. HMI became Horizontal Machining & Manufacturing Inc. and purchased a local welding shop. HMMI was able to invest heavily in cutting-edge automated equipment and robotic welding capabilities, allowing us to provide quicker nationwide delivery of higher-quality, higher-volume custom components.

TransfOrming Big Ideas intO Oversized Reality 

HMMI spent the next ten years focusing on ensuring our customers’ complete satisfaction, honing our metal fabrication expertise, and developing long-lasting relationships built with American-made quality and small-town pride. Then, in 2014, we took our next step of growth for our customers, expanding our facilities and capabilities to meet the ever-growing need for larger weldments. 

We commissioned our four-seam boom welder, brought in our Okuma, an impressive 5-axis machining center, and expanded to our current 100,000-square-foot oversized fabrication facility, complete with a state-of-the-art indoor steel storage center. We proudly keep a wide selection of the industry’s most in-demand materials to meet America’s oversized build-to-demand market.
