Swantec, Inc., is a full service machining and fabrication company located in Princeton, MN. We offer a wide variety of capabilities designed to meet the needs of today's industrial clients, experienced in methods, materials and mechanics for machine sizes from mini to maxi.


Our company was founded by Dick Swanson in 1978 as an engineering design firm, located in Plymouth, MN. In 1988, current president Jay Swanson joined his father in the business. In the late 1980's, Swantec expanded our line of services to include fabrication, machining and assembly.

As the business continued to grow through the years, we moved to our current location in Princeton in 2005. By building this new facility, we doubled the size of our operations to better meet the needs of our current customers and future customers as well.

Our 15,000 sq. ft. facility houses our many work areas,  including welding, plasma cutting, water jet cutting and conventional and CNC machining.

The expansive production space also allows for larger material handling utilizing 5 and 10 ton overhead cranes with 40' and 75' spans.
