Rotational Moulding, also known as Rotomoulding is incredibly versatile, able to produce a wide range of products of various shapes and sizes in a cost effective manner. This process is unique amongst plastics moulding processes because the heating, shaping and cooling of the plastic all take place inside a hollow mould. Improvements in process control and developments of plastic powders over the past two decades have resulted in a significant increase in the usage of the rotational moulding process. Moulds for rotational moulding are also less expensive as there are no internal cores and the moulds don’t have to withstand any high pressure. Rotational moulding has inherent design strengths, such as consistent wall thickness and corners that are virtually stress-free. Inserts, threads, handles, surface detail and reinforcing ribs can all be part of the design. In many cases rotational moulding is the only process to produce a product.
