We are a proven, long-standing leader in custom injection molding, with a history of more than three decades. In 1977 Sussex Plastics, Inc. was formed in Sussex, Wisconsin by an ambitious immigrant from Hungary, Lorand Spyers-Duran. His small but industrious group of employees grew to be the modern, integrated manufacturer that is now Sussex IM.

As an industry leader, we keep moving forward with cutting-edge technologies and lean manufacturing practices. Our state-of-the-art Innovation Center is the hub of SussexIM, where dedicated employees converge to create the quality products our loyal customers expect.
