Rotational molding is the manufacturing process to form hollow cavity parts in all shapes and sizes. This is a cost-effective method to produce large polymer parts. Polymers are added into a mold that’s heated and rotated slowly. The simultaneous heating and rotation distributes and fuses the resin on the inner surfaces of the mold. The result is a product that contains seamless parts with a uniform wall thickness with more material in corners to absorb shocks and stresses where they occur most.
