Rotation mouldingA plastic moulding process especially suitable for hollow parts and parts with low residual stress (no stress corrosion). Rotational moulding are carried out in four steps.

First, the required amount of plastic material is filled into the mould which is then closed. While rotated around two rotational axes the mould is first heated to the melding temperature of the plastic. Then it is cooled again.

Finally the mould is opened and the finished part is removed. No finishing operations are required like removal of runners. Mainly for smaller production volumes.
