Learn about M & W Shops, Inc. and it’s history

Grown out of a part time business






Thank you for having interest to learn about M & W Shops – Custom Metal Fabricators. In 1972, Walter T. Haag and Larry Zamba founded M & W Shops, Inc., in Sturtevant, WI. The company, doing welding for J.I. Case Foundry worked on a part-time basis.  Business increased and M & W Shops moved to its current location in Union Grove, WI in 1976.  At that time, the company employed one full time employee. In 1981, Wally W. Haag became president of M & W Shops, Inc. and the company began to diversify and flourish. The purchase of fabrication equipment began the fabrication of structural weldments for building contractors and construction companies. The beginning years of M & W Shops also saw the fabrication of specialized industrial vacuum cleaning equipment.

Over the next ten years M & W Shops grew into a full time fabricating and welding shop .  Kraftwell Automation was also acquired, which is now Kraftweld, a division of M & W Shops.  To accommodate growth, a new 28,500 square foot facility was built in 1991. In 1992, M & W Shops began the journey into the world of industrial vacuums, thus the beginning of Multi-Vac.

President and owner, Wally Haag has worked in the industrial vacuum field since 1974.  In the early 1990’s, using Mr. Haag’s experience in engineering of heavy duty industrial vacuum equipment and metal fabricating, Multi-Vac was formed. Multi-Vac started with a new maintenance friendly product line of industrial vacuum equipment, loaders, and conveyors. Since that time, Multi-Vac has become a well known and respected name. Multi-Vac equipment is used in steel mills, foundries, cement and brick plants, as well as in the mining, plastic, rubber and chemical industries. Our industrial vacuums can be found from the West Coast to the East Coast, as well as Canada, Mexico, South America, and China. In 2008, M & W Shops progressed into the dust collecting business with specialized Multi-Clean dust collectors.
