Rotational molding involves four key steps: charging the mold with plastic powder, heating and rotating the mold to distribute the melted plastic, cooling, and finally demolding the finished product. The heating phase, which accounts for most energy demand, traditionally depends. . Our solar plastic molding systems use free solar heat from heliostats instead of expensive fossil fuel to make plastic parts. By eliminating the need to burn fossil fuel we make the molding process much cleaner and lower-cost. Traditional applications for rotationally molded parts include large storage tanks, toys, kayaks, fuel tanks, hydraulic tanks, coolers, storage, and recreational equipment. One of the great features of. . Solar thermal energy offers a viable way to cut emissions and energy costs in industry if it can affordably meet roto molding's high heat demands.
