1089: Development of a Rotational Molding Machine with Integral Heating and Cooling Passages within the Mold
Jared A. Sunday, Pennsylvania State University, The Behrend College, Erie, PA
Rotomolding is a process that is traditionally used to make larger complex shaped parts. A mold, traditionally, attached to a spider and arm, is moved through three or four different zones for loading, heating, cooling, and unloading. The mold(s) are rotated around two axes to allow the material to strike all internal surfaces of the mold. The heating occurs in large ovens where the mold is heated by radiation and convection until the plastic melts and coats the inside walls of the rotating mold. This paper will present ongoing construction and theory behind development of a rotomolder with integral heating and cooling passages within the mold.
