Types of Rotomolder Machines

The machines used to power rotational molding are called rotomolders.

Rotomolders commonly have four parts: oven, molds, mold spindles, and cooling chamber. Molds give shapes to plastics and are manufactured by two methods, welding or casting. The oven is used for heating the molds, whereas the mold spindles help in giving uniform coating; they are mounted on a rotating axis. The cooling chambers assist in hardening the material by exposing the mold to low temperatures.

Rotomolders come in a variety of designs, including carousel, clamshell, rock and roll, vertical, and shuttle machines. This design variation allows for both simple and complex design.
