Rotational moulding has been available as a processing method for plastics for about 30 years. However, it is only within the last decade that substantial developments have started to take place so that the process can now be competitive with injection moulding and blow moulding for the production of complex shapes. This paper reviews the current state-of-the-art and highlights the aspects of rotational moulding which are relevant to moulders and designers. The text is aimed particularly at those who may be unfamiliar with the process.
