Leaving layup, the result is a loaded closed tool that could go straight to curing.  The only issue with that is through the layup process we have unwittingly trapped a bunch of air in the layup.  Laying down sheets of carbon is not unlike laying down stickers, add to that a lot of complex curves and it is easy to visualize a bunch of small air pockets getting trapped.  If that air remains in place, it can cause voids, surface defects, and a host of both structural and cosmetic issues. By envelope bagging the tool, venting the bladders to atmosphere, and drawing vacuum on the tool, we evacuate as much air from the laminate as possible.  We do this with the tool slightly warmed in order to drop the resin viscosity and aid in ply sliding.
