A rotational molding machine designed in shuttle style is positioned in a straight line, with an oven and two trolleys with arms at its center. There are cooling chambers and loading stations on both sides. While one trolley rotates the mold into the oven for heating, the other trolley stops on the opposite side for loading or demolding.
This setup provides flexibility for manufacturing larger products, and even smaller products can be produced with high productivity. Additionally, the equipment is relatively simple and easy to maintain. Currently, this type of rotational molding machine is widely used in our country.

1.Loading: The rotomolding process begins with loading a measured quantity of polymer resin, usually in powder form, into the mold. The mold is then securely closed to prevent resin leakage during the heating and rotation stages.
2. Heating: Once loaded, the mold is transferred to the oven chamber, where it is subjected to controlled heating. The heat causes the resin to melt and adhere to the inner surfaces of the mold, gradually forming the desired shape.
3. Rotation: Simultaneously, the mold undergoes bi-axial rotation within the oven. This rotational movement ensures uniform distribution of the molten resin, resulting in consistent wall thickness and mechanical properties across the finished part.
4. Cooling and Unloading: After the desired wall thickness is achieved, the mold is removed from the oven and cooled to solidify the plastic part. Once cooled, the mold is opened, and the finished product is extracted, ready for further processing or assembly.
