Pre-measured plastic resin (usually ground polyethylene which is similar in appearance to ground sugar), is loaded into each mold. Then the molds are moved into the oven where they are slowly rotated on both a vertical and horizontal axis. The melting resin adheres to the hot mold and coats every surface evenly. Once the parts are cooled using air and water, they are released from the mold. DESIGN ADVANTAGES With proper design, rotational molding offers advantages over other molding processes. Parts can be molded as one piece, eliminating seams, and assembled parts. The process also offers consistent wall thickness and stronger outside corners that are virtually stress free.
