a hollow mould is filled with a powder resin and then rotated bi-axially in an oven until the resin coats the inside of the mould and cures.

The mould is then cooled and the part removed. There are many advantages to this process. A primary advantage over other processes is size; some of the largest ovens now incorporate a 5.5m swing. Entire boat hulls and automobile bodies are being roto-moulded in one piece. On the small part end, many small PVC parts such as ear syringes and face masks are rotationally moulded.
