  • Patent number: 6754557
    Abstract: The present invention generally relates to a system and method for manufacturing plastic injection mold cavity components. More specifically, the present invention provides an integrated system and method for manufacturing plastic injection mold cavity components, which integrates manufacturing between two or more subcells. In one embodiment of the invention, a supercell system integrates two or more subcells, in which component workpieces and electrodes are machined. A supercell may include a computerized master control unit, configured to monitor and provide instructions for a master robot that delivers and retrieves workpieces and electrodes to two or more subcells. Thus, two or more subcells may be integrated by the master control unit, the master robot, a track or path that the master robot follows, identification indicia attached to workpieces and electrodes, a combination thereof or any other components of supercell that may suitably integrate two or more subcells.
