Rotational MoldingRMB Products' rotational molding and lining techniques deliver seamless products for numerous unique and demanding applications. We utilize a variety of rotational molding equipment, including our extensively modified Rock n Roll machine, which has produced parts as large as 90 inches in diameter by 240 inches in length. Rotomolding 101The basic concept of rotomolding is to place an appropriate amount of the desired polymer powder into a mold. The mold is indexed and rotated under heat until the plastic is molten. The mold is rotated about two perpendicular axis to allow coverage of the plastic to all mold surfaces. This gravitational process relies on plastic tumbling inside a rotating mold to give an even wall thickness. Once the desired cure time has been satisfied the mold is then taken into a cooling station, followed by a load/unload station where the part is unloaded.
