A method for rotational molding a thermoplastic article using a mold made of a fiber reinforced thermoset resin which has a heat distortion point above the melting point of the thermoplastic material. Metal or other materials may be used to provide different coefficients of heat transfer at preselected portions of the mold. The entire mold may include a thermal coefficient modifier to increase the heat transfer rate of the mold uniformly over the entire mold in addition to the preselected portions.
