Solar Plastic Molding: Rotational Molding
Related Product: Solar Plastic Shredding, for waste processing and densification.
LightManufacturing builds and operates self-contained Solar Rotational Molding systems which make large plastic products like water tanks without burning fossil fuels. This reduces the product cost and eliminates greenhouse gass emissions. The factories can be deployed to any sunny area, and do not require any infrastructure (no grid-energy connection).
We currently operate in California and Hawaii.

Our solar plastic molding systems use free solar heat from heliostats to make plastic parts, instead of expensive fossil fuel. Our Solar Rotational Molding (SRM®) factories are complete systems – just add molds and plastic. Energy for mold rotation is supplied by integrated photovoltaic panels. Models
