Rotational molding is a low-pressure process and the strength required from the molds is minimal.
This results in its ability to produce large or complex parts on short notice, using inexpensive molds.
Due to the low tooling cost rotational molding is ideally suited to producing prototypes, and small or large quantities of production parts.
The low processing pressure involved in rotational molding has the added advantage of producing parts which are relatively stress free, as compared to high pressure processes.
This advantage of the process is especially important when considering large, load-bearing parts in applications which must provide corrosion and stress-crack resistance.
