An in-line metallizer assembly comprising: a plurality of part carriers each adapted to hold a plurality of parts, the part carriers comprising a plurality of rotatable pin fixtures, a lifting body, a support frame that is spaced apart from the lifting body, and a biasing element comprising a pin that is adapted to slide relative to at least one of the lifting body or the support frame of the part carrier and a spring that is configured to apply a force to the lifting body or the support frame, wherein the biasing element may be compressed such that a relative position between the lifting body and the support frame is repositionable along the pin, wherein the rotatable pin fixtures are adapted to rotate with respect to the support frame; a vacuum chamber comprising an entry port that passes through a vacuum chamber wall; an integrated sputter coater positioned inside of the vacuum chamber; an external rotating actuator exchange comprising: one or more actuator arms (22, 24) connected to a rotating pivot that are positioned outside of the vacuum chamber, the one or more actuator arms being operable to extend from and retract towards the rotating pivot, and the rotating pivot being operable to rotate the external rotating actuator exchange; and one or more external door clasps that are coupled to the actuator arms and that selectively seal around the entry port of the vacuum chamber, the one or more external door clasps comprising one of a robotic grip or one or more pins or protrusions operable to releasably engage the one or more part carriers on the conveyor system; and an internal rotating actuator exchange positioned inside of the vacuum chamber comprising: one or more internal actuator arms (37, 33) adapted to rotate about an internal rotating pivot, the one or more internal actuator arms being operable to extend from and retract towards the internal rotating pivot, and the internal rotating pivot being operable to rotate the internal rotating actuator exchange; and one or more internal door clasps that are coupled to the internal actuator arms and which selectively seal around the entry port of the vacuum chamber. a plurality of part carriers each adapted to hold a plurality of parts, the part carriers comprising a plurality of rotatable pin fixtures, a lifting body, a support frame that is spaced apart from the lifting body, and a biasing element comprising a pin that is adapted to slide relative to at least one of the lifting body or the support frame of the part carrier and a spring that is configured to apply a force to the lifting body or the support frame, wherein the biasing element may be compressed such that a relative position between the lifting body and the support frame is repositionable along the pin, wherein the rotatable pin fixtures are adapted to rotate with respect to the support frame;
