1. A curing tool assembly for composite manufacturing, comprising:
a curing tool comprising a tool surface defining a resin channel having a channel axis;
a cover plate overlaying at least a portion of the resin channel along the channel axis, the cover plate defining a plurality of openings in fluidic communication with the resin channel, the plurality of openings arranged to provide different flow capacity through different portions of the cover plate along the channel axis;
a fluid impervious layer sealable against the curing tool to define a sealed volume between the fluid impervious layer and the tool surface; and
a differential pressure generator configured to establish a differential pressure within the sealed volume.
