The present invention is a casting machine for casting parts in a mold out of a metal using a metal feed stock. The machine includes a processing cylinder formed in a thermally conductive block, said processing cylinder having a processing chamber and opposite first and second ends, the first end of the processing cylinder being configured to receive the metal feed stock. The machine further includes an injector cylinder formed in the thermally conductive block adjacent the processing cylinder, the injector cylinder having a shooting pot coupled to the second end of the processing cylinder by a passage configured to permit feed stock to pass from the processing cylinder into the shooting pot, a nozzle coupled to the injector cylinder configured to couple to the mold. The device includes a processing drive for driving the feed stock from the first end of the processing cylinder through the passage into the shooting pot and a heater thermally coupled to the processing cylinder. The heater and processing cylinder are configured to heat the feed stock such that the feed stock becomes progressively more liquid as it passes from the first to the second end of the processing cylinder. The machine further includes an injector plunger coupled to an injector actuator for driving the plunger sufficiently to force the metal from the shooting pot through the nozzle and into the mold.
