What is Rotational Molding?

How do customers start a new Custom Rotomolding Project?
New custom rotational molding projects are usually started with a meeting consisting of a product consultation, where features, functions and expectations are shared. Then the design process will lead to the creation of new tooling or molds. Once the tools are complete, the custom rotomolding process can begin manufacturing.
