Abstract
Official abstract text for this publication.
A resin laminate manufacturing method includes providing a pair of split mold blocks one of which has a cavity provided with a plurality of protrusions extending toward the other mold block, preparing two molten thermoplastic resin sheets each having an adjusted thickness, feeding the two molten thermoplastic resin sheets between the pair of split mold blocks with a predetermined gap left therebetween, forming a hermetic space between one of the sheets and the cavity of the one mold block opposed to an outer surface of the one sheet, sucking air in the hermetic space from the side of the one mold block, pressing the outer surface of the one sheet against the cavity of the one mold block to shape the one sheet, forming cup-shaped portions, and clamping the pair of mold blocks.
