Overhead racks for hanging sheets may be equipped with tracks and trolleys leading to forming equipment to facilitate handling of the sheet note the special considerations section for plexiglas mc acrylic.
At this point the pliable polycarbonate sheet is lowered onto the mold.
As you ll need to put the plastic sheet into the oven this is your size limitation.
