Our History

Polaroid images

In 1976, E. Duncan started his business under the name of Bee Fabrication. In 1985, a partner was taken on, and the name was changed to Dunweizer Machine and Fabrication. In 2001, the company split with Ed Duncan taking the name Dunweizer Fabrication, and the partner taking the name Dunweizer Machine. Both companies reside under the same roof, with the same phone number, but they remain separate entities. Dunweizer Fabrication has a full machine shop, able to do turning, boring, keyways (internal and external), as well as drilling and milling. In our fabrication shop, we do rolling, shearing, brake work, welding of all types and on most materials, steel, aluminum, and stainless steel.
