Abstract:
A method of molding a plastic frame for a graphite plate assembly comprising the steps of:positioning a graphite plate member in a mold cavity, said graphite plate member having a top surface and a bottom surface defined thereon, peripheral sides defined along the periphery thereof, and mold shut-off means provided on said top or bottom surfaces of the graphite plate member for preventing injected plastic from flowing onto said top or bottom surfaces, respectively; positioning a mold core against said graphite plate member and said mold cavity, thereby defining a cavity space surrounding said peripheral sides of said graphite plate member; injecting molten plastic into said cavity space; and separating said mold cavity and said mold core, and removing the resulting molded plastic frame and graphite plate therefrom.
