Whats rotomolding

Rotomolding, short for rotational molding, is a process for manufacturing durable plastic parts for many markets. A heated hollow mold is filled with material. It is then rotated, 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 and cooling phases.

There are many advantages to the rotational molding process. Tooling cost is much lower, which often makes rotomolding a more cost effective method, especially for smaller quantities. The process has virtually no size limitations and parts are produced with an even wall thickness, even at the corners. Complex shapes with molded in handles, graphics, threads, and inserts can all be part of the design, saving you time and money by eliminating secondary operations.
