ABSTRACT:
A flow molding apparatus with multiple layers of molds and electrodes is disclosed. In an exemplary embodiment, the apparatus includes top and bottom electrodes with an intermediate electrode positioned therebetween. A first mold is disposed between the top electrode and the intermediate electrode, and a second mold is disposed between the bottom electrode and the intermediate electrode. Preferably, a plurality of metallic locking fixtures are attached to the top and bottom electrodes for securing the apparatus in a closed position. An electromagnetic energy source is operably connected to the electrodes such that the top and bottom electrodes are grounded and the intermediate electrode carries a high voltage. As such, an alternating electric field may be established across each of the first and second molds during a heating cycle.
