Title:
METHOD FOR MANUFACTURING A RESIN LAMINATE
Document Type and Number:
WIPO Patent Application WO/2011/081224
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a resin laminate. Said method includes: a step in which a two-piece mold is provided, wherein the cavity of one piece of the mold is provided with a plurality of protrusions that protrude towards the other piece of the mold, and two thermoplastic resin sheets in a molten state are prepared with regulated thicknesses; a step in which the two molten thermoplastic resin sheets are positioned at a prescribed separation from each other between the two pieces of the two-piece mold so as to protrude outside a ring-shaped pinch-off; a step in which a sealed space is formed between one sheet and the cavity of one mold piece facing the outer surface of that sheet; a step in which suction is applied to the aforementioned sealed space from the mold piece side and the outer surface of that sheet is pushed up against the cavity of that mold, thereby diluting that sheet and forming a depression; and a step in which the mold is clamped shut, thereby bonding the outer edges of the two molten thermoplastic resin sheets to each other and also bonding the tip of the depression formed in one sheet to the inner surface of the other sheet.
