  • Patent number: 8535582
    Abstract: The present invention relates to a method and molding system (1) for forming a molded plastic article by wireless control. The molding system includes a primary controller (12) that is adapted to engage in wireless communications with the carriage controller (45) of one or more self-propelled carriages (15). Each carriage (15) includes a carriage location indicator (62) that determines the location of the carriage, which is transmitted substantially continuously to the carriage controller (45), and then communicated substantially continuously and wirelessly from the carriage controller to the primary controller (12). The primary controller (12) wirelessly communicates position directives (e.g., a polymer introduction station position directive) to each carriage controller (45), which correspondingly provides operational position instructions to each carriage's respective propulsion system (30), so as to re-position at least one carriage.
