Isn’t Plastic Molding Mostly Done in a Few Large Manufacturing Areas?

Most people think of injection molding when they think of plastic manufacturing – this process is very capital intensive, and produces high volumes of relatively small, thin-walled objects – i.e. plastic cutlery, small toys, flashlight bodies, etc.

Rotational molding is best at making relatively large objects – from something 6″ across to very large objects such as 8′ diameter water tanks or 10′ long boats, with walls up to 1″ thick.  These large, heavy objects do not pack efficiently, and shipping them is essentially to ‘ship air’.  As a result, Rotational Molding is distributed across all markets – European Rotomolders making parts for Europe and for export, Asian rotomolders making parts for Asia and for export, etc.  The distributed nature of rotational molding allows LightManufacturing’s SRM process to be deployed as needed in solar-rich regions.
