1. An in-line metallizer assembly comprising:
a conveyor system for conveying parts towards and away from a vacuum chamber;
an external rotating actuator exchange operable to exchange one or more parts between the conveyor system and the vacuum chamber;
a pressurized enclosure maintained at a pressure above ambient pressure throughout the exchange of the one or more parts between the conveyor system and the vacuum chamber, the pressurized enclosure at least partially surrounding the external rotating actuator exchange and comprising an endwall having an opening, wherein at least a portion of the external rotating actuator exchange is operable to selectively extend through the opening of the endwall;
one or more external door clasps configured to selectively form a temporary seal with the endwall of the pressurized enclosure; and
a pressurized gas delivery system fluidly coupled to the pressurized enclosure and providing pressurized buffer gas to the pressurized enclosure at a rate greater than environmental gas enters the vacuum chamber during the exchange of one or more parts between the conveyor system and the vacuum chamber.
