In-line metalizer assemblies can include an external rotating actuator exchange that can be operable to exchange one or more parts between a conveyor system and a vacuum chamber, and an internal rotating actuator exchange within the vacuum chamber that can be operable to receive the one or more parts from the external rotating actuator exchange, transition the one or more parts to a sputter coater integrated with the vacuum chamber for metallizing, and return metalized one or more parts to the external rotating actuator exchange such that the external rotating actuator exchange can return the metalized one or more parts to the conveyor system.
