<p>A two-piece transfer seal for coupling a nozzle tip (24) to a nozzle of an injection molding apparatus includes a retaining member (48) removably connected to a downstream end of the nozzle (18) and a removably connected nozzle sealing member (70). The retaining member (48) is comprised of a first material and at least the sealing face of the sealing member is comprised of a second material. In certain applications, the nozzle sealing member (70) is a mold gate insert. In certain applications, the two-piece transfer seal does not retain the nozzle tip, which is metallurgically bonded to the nozzle. <IMAGE></p> |
