A mold (10) for molding thin resin sheets includes a center mold plate (12) and two side mold plates (14, 16) disposed on opposite sides of the center mold plate. The mold plates are oriented generally vertically and parallel to each other, and the side mold plates are narrowly spaced from the center mold plate to define a pair of generally vertical mold cavities (18, 20) on either side of the center mold plate. The side mold plates may optionally include recesses (51) in their generally planar mold surfaces (38, 40) adjacent at least one longitudinal edge of the plate, for molding thin resin sheets with integral edge flanges. The mold includes spacer strips (46, 47) for spacing the side mold plates a precise distance from the center mold plate and parallel thereto. The mold thus permits molding of thin resin sheets having precisely controlled uniform thickness.
