Quality Rotational Molding Services

For years, Stern Companies' total commitment to our clients' goals has included the performance of quality rotational molding services in a timely and cost-efficient manner. We can supply the mold cavity and a heated rotating mold along a horizontal or vertical axis. We have the technical ability and technology needed to execute intricate contours, undercuts, molded-in inserts and double walls.

As we've honed our quality focus over the past 40+ years, we've continued to meet relevant standards such as SAE, ASTM and FDA in addition to being ISO-compliant. Our rotational molding is applied to everything from specialty tanks to containers for water and chemical processing as well as kayaks, playground equipment and childcare seats.
