Rapid Molding, formerly Rapid Molds, builds injection molds and produces custom injection-molded parts from prototype quantities through high-volume production. Founded in 1993 around the goal of cutting mold-build lead times, the North Canton company has since made more than 30 million parts and developed a steel-based prototype approach that supports production-like features without the usual prototype compromises. Its engineers help carry projects from early product development into production, including complex molds and tight-turnaround work.
