Rotational moulding is a process that involves heating a rotating hollow mould allowing plastic resin within to take form.

Moulds in rotomoulding are usually made from aluminium or steel that is cast, machined or fabricated—a process known as tooling.

Poly moulding material often comes in a raw pellet form that is then grounded into powder before being used in the rotomoulding process.

Rotomoulding is an highly practical and beneficial plastic moulding method. Every product designer should have it at their disposal.
