3M’s New Ulm plant opened in 1962 when the company purchased a vacant 33,000 square foot building sitting on 60 acres of property in the southern Minnesota town. The first production line on site made electrical connectors, connectors for telephone lines, and electrical splicing kits.  

Over the years, 3M has constructed several additions in New Ulm to add new manufacturing capabilities for thousands of 3M products.    

Today, the plant is 532,000 square feet in size and employs approximately 700. The diversified manufacturing operation provides products for a wide variety of markets and customers.  

The plant’s 60th anniversary was celebrated in a community celebration on Saturday, Aug. 27th. The New Ulm Journal and KEYC-TV featured coverage of the event.
