Rotational Molding

Where a heated hollow mold is filled with a specific amount of resin and then rotated bi-axially in an oven, softening the material to evenly disperse and stick to the walls of the mold. Each rotation, along with the correct speed are critical. In order to maintain an even thickness throughout the part, the mold continues to rotate throughout the heating phase all the way through the cooling phase.
