Rotational Molding

Rotational Molding:

What is Rotational Molding?

Rotational molding creates hollow plastic parts according to precise specifications – and with low tooling costs. With roto molding, powder or resin is loaded into a hollow mold which then rotates on two axes inside an oven until the inside of the mold is coated uniformly. After the mold is cooled, the hollow plastic part is removed.


Advantages of Rotational Molding

With its low tooling costs and quick tooling modifications, rotational molding is ideal for prototyping and for both low and higher volume production runs. Roto molding tooling ranges from simple two-piece sheet metal molds to multi-piece aluminum molds with articulating features.

Can have varying wall thicknesses, depending on part specifications

Plastic parts can stand up to environmental conditions such as wind and water

Roto molding molds are made quickly and cost-effectively, enabling the customer to do prototypes or short production runs

Can offer you cost benefits over producing the part from fiberglass, steel, or wood

Can include molded-in features such as handles, recesses, inserts, and more
