Royal Custom Plastics began in December 1993 in a small garage and workshop. The early days involved making sales calls, purchasing stock, fabricating, and delivering finished parts. By 1994, the business had grown, leading to a move into the Advance Business Development Center, a small business incubator that provided essential resources like a forklift, loading dock, phone service, and conference rooms.

Within a year, the company outgrew the incubator and relocated to a stand-alone shop in Green Bay, hiring more full-time employees and introducing HAAS CNC Machines. After a decade of steady growth, Royal Custom Plastics expanded again, moving into a 10,000-square-foot facility in the West De Pere Industrial Park. This space offers a front office, a sizeable warehouse, and ample room for essential equipment, including CNC mills, CNC lathes, fabrication tools, and a 12’ x 12’ panel saw.
