The plastic rotational molding process begins with heating polymer powder in a rotational molding machine. The powder is placed in a mold that will be placed in an oven, and the machine will be closed, so that the plastic can fill all the spaces of the mold. The rotational molding machine is then turned on, driving the material into the oven ...Web
