Mayville Engineering Company, Inc.
A contract manufacturer that fabricates, welds, coats, and assembles metal parts and components for big-name OEMs across trucks, construction, powersports, agriculture, and the military. Founded in 1945 by Mayville natives Ted Bachhuber and his uncle Leo in a rented garage behind a Main Street alley in Wisconsin, its first letterhead read "Tools, Dies, and Special Machinery." Today it ranks as one of the largest U.S. fabricators—and it also makes shotshell reloaders under the MEC Outdoors brand.
