Rotomolding also called rotational molding, entails filling a
charge or shot weight of material into a heated hollow mold,
followed by slowly rotating the mold, causing the softened material
to disperse and adhere to the mold’s walls. The mold continues to
rotate at all times during the heating phase to achieve and
maintain an even thickness throughout the part. This rotation also
prevents sagging, or deformation, during the cooling phase.
The distinct advantage of rotomolding is that it is an easier
process than any other when producing large, hollow parts, such as
oil tanks or chairs. Also, the molds used in rotomolding are
significantly less expensive than different types of molds.
Rotomolding generates much less wasted material; excess material
can often serve for another usage, making it economical and
ecological.
Another advantage lies in the molds themselves; they necessitate
less tooling. Consequently, companies could put into production
much faster than other molding processes. This is especially
valuable for complex parts. Rotational molding is also the choice
process for short runs and rush deliveries. The operator can
exchange the molds quickly or use different colors without purging
the mold. With other processes, purging may be necessary to swap
colors.
The main drawbacks are the hard-to-reach areas in the mold and a
long cooling duration that leads to significant mold downtime.
