Custom Mold Makers Since 1971

Rex Plastics is a second-generation, family-owned and operated full-service plastic injection molding contract manufacturer founded in 1971 by Rex Clark.  As a former machinist for the Navy that started the company in his pump house with one machine, Rex landed a customer making emergency vehicle antennas by hand in his second year of business, and we still mold for that customer today.  Rex Plastics is run today by two sons, a niece, and a nephew who carry on the rich tradition of accessibility and customer advocacy the organization was built around.
