Rotational Molding custom parts

Rotational Molding Process

Rotational Mold Process - Idea to Parts

Rotational Molding, also called rotomolding or rotocast, is a thermoplastic process for producing hollow parts by placing powdered resin into a hollow mold and then rotating that mold bi-axially in an oven until the resin melts and coats the inside of the mold.

The mold is then cooled and the part is removed from the mold. Rotational molding can produce small to large, simple to complex parts. See Rotational molding in action

Project development

Advantages of Rotational Molding:

  • Design flexibility allowing complex geometry
  • Cost saving - Projects of 50 to 30,000 are ideal
  • Molds cost less then other molding methods
  • Parts offer strength and durability
  • Stress free parts
  • Short lead times on production
  • Consistent wall thickness
