Rotational Molding

Rotomolding, also known as rotational molding, rotary molding, etc., is a hollow molding method for thermoplastics. The method is to first add plastic raw materials into the mold, and then the mold is continuously rotated along two vertical axes and heated. Under the action of gravity and thermal energy, the plastic raw materials in the mold are gradually uniformly coated and melted and adhered to the mold cavity. The whole surface is formed into the required shape, and then cooled and shaped to get the final product.
