    摘要: An extruder barrel segment includes an integral heat-exchanger fluid flow passageway device that is formed into a desired shape. The barrel segment is formed employing a process, such as near net shape casting or lost wax shape casting. A mold pattern is used to make a casting mold of the barrel body. The passageway device is then located into the mold and positioned to ensure that there is no interference. The mold is filled with molten metal that flows around the passageway device and encapsulates it into the barrel body. The mold gates are removed, and the casting is ready for machining.
