Rotomolding

Rotomolding

Rotational molding is a highly versatile manufacturing option that allows for unlimited design possibilities with the added benefit of low production costs.

PROCESS OVERVIEW
Rotational molding is a four-step process:

- Loading the mold with plastic resin.
- Heating and rotating the mold in an oven (Rotomolding machine).
- Cooling of the mold.
- Extracting the plastic product from the mold.

Several molds may be placed on the machine at the same time. A plastic resin is loaded into each mold, and then the molds are moved into the oven where they are slowly rotated on both the vertical and horizontal axis. The melting resin sticks to the hot mold and coats every surface evenly. The mold continues to rotate during the cooling cycle so the parts retain an even wall thickness. Once the parts are cooled, they are released from the mold. The rotational speed, heating and cooling times are all controlled throughout the process.
