Rotational moulding offers a great deal of freedom in design and has fewer restrictions than
other processes used for the manufacture of plastic parts. It can be used to produce open or
closed items with dimensions that can start from diameters as small as 25-50 mm. The shapes
can be simple (spheres, containers) or complex (fuel tanks, automotive components).
Parts can be moulded with thicknesses starting from 1.0 mm up to 50mm.
The parts may be coloured or transparent, flexible or rigid. Rotational moulding is suitable for small production runs, but it can be used for the
production of 50,000 – 100,000 parts/year. Above these values a more automated process
should be considered. However, in cases where the rotational moulding is the only viable
process, higher production outputs can be obtained using multiple moulds and
machines.
