Rotational Mold Process - Idea to Parts
Rotational Molding, also called rotomolding or rotocast, is a thermoplastic process for producing hollow parts by placing powdered resin into a hollow mold and then rotating that mold bi-axially in an oven until the resin melts and coats the inside of the mold.
The mold is then cooled and the part is removed from the mold. Rotational molding can produce small to large, simple to complex parts. See Rotational molding in action
