A ROTATIONAL MOLDING OVERVIEW Rotational Molding is a unique plastic molding process used to produce large hollow parts. Often referred to as rotomolding, because the molds are slowly rotated in an oven spreading the resin inside using centrifugal force to fill the walls of the mold. Depending on the purpose of part, wall and corner thickness can vary to suit that requirement. This is critical for water and air tight containers and tanks. Rotational molding is a versatile manufacturing option with many benefits over standard thermoform, injection and blow molding. This process makes it possible to design very large hollow pieces in virtually any shape, size, color and configuration. Generally, pieces are lightweight with strong structural integrity. The process uses a variety of mold types and molding machines that contain loading, heating and cooling areas. Once a mold is bolted to one of the machine’s rotating arms, the pre-measured plastic resin is loaded. Several molds on as many as three arms can be used at the same time. The molds then move into the oven and rotate on both the vertical and horizontal axis. The melting resin adheres to the mold and lays down a thick even coating, filling in areas that need more structure. The rotating continues during the cooling cycle where the part retains an even thickness.
