n The process of forming hollow articles from liquid materials by rotating a mold containing a charge of the material about one or more axes at relatively low speeds until the charge is distributed on the inner walls of the mold by gravity and hardened by heating, cooling, or curing. Rotation about one axis is suitable for cylindrical objects. Rotation about two axes and/or rocking motions are employed for completely closed articles. The process of rotational casting of plastisols comprises placing a measured charge of plastisol in the bottom half of an opened mold, closing the mold, rotating the mold about one or more axes while applying heat until the charge has been distributed and fused against the mold walls, cooling the mold until the deposit has gained strength, opening the mold, and removing the article.
