At least one sheet retainer attaches to the uppersurface of a frame the surrounds at least a portion of the first mold portion perimeteredge. Each sheet retainer includes a clamp portion that is positionable relative to theperimeter edge of the first mold portion. With a first portion of a heated thermoplasticsheet retained within the clamp portion a step of the method includes independently,reversibly and laterally moving each sheet retainer, towards and/or away from theperimeter edge of the first mold portion. Sheet retainer positioning allows localizedcontrol over the contacting of the interior mold surface and heated thermoplastic sheetthickness which controls the thickness of vanous portions of the final molded article
