1. A rotary-style BFS manufacturing system, comprising:
a BFS mold comprising two cooperatively matched mold halves, each mold half defining a plurality of vacuum cavities;
a mold holder coupled to each mold half, the mold holders each comprising (i) a first vacuum port in communication with a first subset of the plurality of vacuum cavities of the respective mold half and (ii) a second vacuum port in communication with a second subset of the plurality of vacuum cavities of the respective mold half; and
a vacuum slider in communication with the mold holder, the vacuum slider comprising two vacuum slots, each vacuum slot being operable to (i) be engaged with the first vacuum port of a respective mold holder at a first time in a rotary BFS cycle and (i) be engaged with the second vacuum port of a respective mold holder at a second time in the rotary BFS cycle.
