Explanation

rotational molding is also called rotational molding, rotational casting, rotary molding, etc. It is to put plastics materials into a metal mold. The mold rotates while heating around two mutually perpendicular axes. Heating methods include infrared radiation, hot air, etc. Due to the continuous flipping of the material during the rotation process, the material rotates 360 ° with the mold. After repeated heating and rotating, the plastics raw materials are gradually evenly coated, fused and adhered to the entire surface of the mold cavity, formed into the desired shape, cooled, shaped and demoulded, and finally hollow container shaped products are obtained.
