Abstract
A method of rotationally molding a part to include a platform therein is provided. The method includes providing a mold and mounting the platform adjacent to, and preferably connected to the wall of the mold. Resin is deposited in the mold and the mold is closed. The mold is heated and rotated around at least two axes. The molten resin substantially covers the interior wall of the mold and the portion of the platform exposed therein. Rotation continues as the mold is cooled whereby the resin solidifies into a self-sustaining configuration. The resulting part is removed with the platform receiving resin thereon incorporated in the part resulting in a reinforcement oriented in spanning relationship to an interval defined by spaced-apart regions on the mold wall. The placement of the platform may be selected, whereby the resin and platform provide structural reinforcements for the part, lifting points incorporated into the part, or electrical grounding sites which are formed during molding.
