What is Rotational Molding?

We’re always talking about our rotational molding process (often referred to as roto molded), but what is roto molding?

The process is designed to form hollow, seamless, stress-free parts with fairly uniform wall thickness, creating durable products.

This is done with conventional roto molding equipment by simultaneously heating and rotating a thermoplastic resin in a closed mold. Rotation and heat continue until the all the resin is evenly distributed on the interior mold surface and fusion is complete. The mold then moves to a cooling chamber where is it cooled.
