Rotational Moulding

Rotational moulding involves a heated hollow mold which is filled with a charge or shot weight of material. It is then slowly rotated (usually around two perpendicular axes), causing the softened material to disperse and stick to the walls of the mold. In order to maintain even thickness throughout the part, the mold continues to rotate at all times during the heating phase and to avoid sagging or deformation also during the cooling phase. The process was applied to plastics in the 1950s but in the early years was little used because it was a slow process restricted to a small number of plastics. Over time, improvements in process control and developments with plastic powders have resulted in a significant increase in usage.

With proper design & tooling parts assembled from seversal pieces can moulded as one part, eliminating hgh fabrication cost rotational molding is ideal for prototyping and for both low and higher volume production runs. Roto molding tooling ranges from simple two-piece sheet metal molds to multi-piece aluminum molds with articulating features.
