US Patent 7632438 Intelligent manifold and injection molding machine

An injection molding machine system includes a hot runner comprising a memory device configured to contain at least one process control parameter. The memory device may transmit a signal representative of the process control parameter to a machine controller associated with the injection molding machine system. The machine controller may generate control signal to operate the injection molding machine system based on, at least in part, the signal from the memory device, wherein the at least one memory device is pre-programmed to have the information pertaining to the at least one process control parameter prior to a first run in the injection molding system.
