The principle of rotational molding of plastics is simple.
Basically the process consists of introducing a known amount of
plastic in powder, granular, or viscous liquid form into a hollow,
shell-like mold.The mold is rotated and/ or rocked about two
principal axes at relatively low speeds as it is heated so that the
plastic enclosed in the mold adheres to, and forms a monolithic
layer against, the mold surface. The mold rotation continues during
the cooling phase so that the plastic retains its desired shape as
it solidifies. When the plastic is sufficiently rigid, the cooling
and mold rotation is stopped to allow the removal of the plastic
product from the mold. At this stage, the cyclic process may be
repeated. The basic steps of (a) mold charging, (b) mold heating,
(c) mold cooling, and (d) part ejection.
