What is Rotomolding?

Rotomolding is a manufacturing process also known as Rotational Molding. Polyethylene Pellets or Liquid PVC is filled into a hollow mold and rotated under heat around two axis causing the material to adhere to the wall producing an article with a uniform wall thickness.

The controlled process is a cost-effective method of manufacturing durable container-like products which are environmentally friendly and used in a variety of industries including marine, automotive, recreational, and more.
