Company History
Feb. 1, 1963 Mr. Wesley Swanson founded Sons Tool Inc in North Minneapolis.
1965  Business growth forced the company to a larger facility in Roseville, MN.
1965 - 1975  From 1965 through 1975 Sons Tool Inc continued to perfect their stamping capabilities and processes.
1975   Mr. Swanson decided to return to his home state and built an 18,000 sq. ft. facility in Woodville, WI., just 45 miles from Minneapolis & St. Paul, MN.

Capabilities explanded by adding sub-assembly type work including in-house welding, bracker riveting, and hardware insertions.
1993  As business continued to grow, a 12,000 sq. ft. addition was added - bringing the total sq. footage to 30,000.

Sons Tool, Inc. purchased C.M. Bubak, a company that specialized in smaller size stampings.

Over the next four years two additional office expansions were added to accommodate additional staff.
1995  A 20,000 sq. ft. addition was completed bringing the total sq. footage to 50,000.
1997  Laser capability was added to enhance the ability to turn pre-production samples and tool development around in a shorter period of time.
1997 - Current  We improved efficiencies by continuing to upgrade equipment and processes.
Today Sons Tool Inc continues its commitment to make the customer’s job as easy as possible.

Stampings can be made as complete-to-print as the customer needs by adding secondary services such as plating, painting, heat treating, or silk screening.
