Abstract
In order to survive the competition, the processing cycle time and the energy consumption of the rotational foam molding process must be reduced to a fraction of its current levels without compromising product quality. This paper introduces a novel extrusion-assisted rotational foam molding process for the manufacture of rotational moldings having adjacent, but clearly distinct, layers of an integrated solid (non-cellular) skin boundary layer encapsulating a cellular core structure, consisting of identical or compatible polyolefin grades, that achieves significant savings in processing cycle time duration and energy consumption. It introduces non-chilled extruded foam as a foamed core-forming material, in real time, directly into a uni-axially rotating hot mold through a dedicated mold “injection” port onto the already formed un-foamed soft skin layer.
