  • Method of manufacture of graphite plate assembly
    Patent number: 6596428
    Abstract: There is provided herein a graphite plate assembly including an injection molded plastic frame which carries the border detail for the graphite plate. The planar graphite plate is provided with a frame engaging protrusion around its periphery and with beveled edges bordering the broad top and bottom surfaces of the graphite plate. These beveled edges seal against respective beveled surfaces of the mold to prevent plastic from entering onto the graphite plate surfaces during injection molding of the frame. The graphite plate is held in position within the mold by a vacuum grid and locating pins while plastic is injected into the cavity space around the graphite plate from a plurality of spaced plastic injection gates.
    Type: Grant

  • Compression molding apparatus and method
    Publication number: 20030030185
    Abstract: The apparatus includes a mold core, a mold cavity and a moveable ring surrounding the mold cavity. A graphite/resin mixture is loaded into the mold cavity, filling a well area defined by the ring. The mold core is then pressed against the mixture in the mold cavity and heat is applied to harden the resin. The mold core is then raised, the ring is lowered, and the finished part is ejected.
