Rotational Molding

Rotational molding is a molding process that allows many design possibilities all at a low production cost. To start the rotational mold process, there must be a mold already created. The molds are filled with resin, loaded into a machine and then rotated on vertical and horizontal axis. The molds continue to rotate throughout the whole time they are in the machine to ensure that the thickness of the resin is evenly distributed. When the molds cool, the products are removed.

Rotational molding is preferred to other types of molding because it is relatively inexpensive and parts that are usually assembled from several pieces can be molded together. The actual rotating molding itself also proves to be extremely effective as the evenly distributed thickness gives the product consistency and stress free corners. Products that are made from a rotational molding process can also be made flame retardant or weather resistant.
