Rotational Casting is the process whereby a liquid is poured into a mold and rotated by a rotational casting machine to coat the inside of the mold. When the liquid hardens the mold is taken out of the machine and opened to reveal a hollow casting. This process produces parts with a very fine finish. Air holes are eliminated and the finest of details are reproduced.

Rotational casting produces a hollow part that saves material, saves casting time and provides a higher level of detail. Examples of rotational casting applications produced by Johnson Plastics are cremation urns and mannequin parts ideal for robotics or displays.
