Rotational molding, or roto molding, is a manufacturing process used to create hollow, seamless, and durable plastic products. The process involves adding powdered plastic material into a mold, which is then heated and rotated biaxially. The heat melts the plastic, allowing it to coat the interior surfaces of the mold evenly. Once cooled, the mold is opened, and the finished product is removed. Roto molding is cost-effective for producing large, complex shapes and is widely used to manufacture tanks, containers, toys, furniture, and automotive components. It offers design flexibility, uniform wall thickness, and minimal material waste.
