Our History
Royal Custom Plastics began in December 1993 in a small garage and workshop. The early days included everything from sales calls and stock purchasing to fabrication and delivery. In 1994, the company moved into the Advance Business Development Center, a small business incubator that offered essential resources such as a forklift, loading dock, and conference rooms.
Within a year, we outgrew that space and relocated to a standalone shop in Green Bay, adding employees and introducing HAAS CNC Machines. After a decade of steady growth, we expanded again into a 10,000-square-foot facility in the West De Pere Industrial Park, now home to our front office, warehouse, and full production floor.

With a loyal customer base, a reputation for precision, and a commitment to innovation, Royal Custom Plastics continues to grow as one of the top Wisconsin plastic fabricators.
