Rotational Molding, also called rotomolding, is a thermoplastic process for producing hollow parts by placing powder or liquid resin into a hollow mold and then rotating that tool bi-axially in an oven until the resin melts and coats the inside of the mold cavity. Next the tool is cooled and the part is removed from the mold.
There are four steps in rotomoulding. Filling the mild with a material, heating the material, cooling until the took solidifies, and finally, removing part from the tools. If you have any more questions, give us a call and we will be glad to answer.
