发明名称 Method And Apparatus For Manufacturing A Molded Product
摘要 An object of the invention is to provide method and apparatus for manufacturing a molded product in which a molded product having precise microstructure, high dimensional precision, low residual stress, low birefringence, high optical-transparency, and excellent mechanical strength can be provided in a three dimensional geometry, thin wall and large-area by a very low molding pressure molding process. The method and apparatus for manufacturing a molded product comprise a resin coating step of coating molten resin 12 onto a forming mold 11 having a minute uneven portion 10 on the surface thereof, a compressing step of pressing the molten resin 12 using the forming mold to thereby arrange the shape of the molded product, and a solidifying step of cooling and solidifying the molten resin 12 . The resin coating step supplies the molten resin 12 to a resin coating device including a discharge port and, while moving the resin coating device, discharges the molten resin 12 onto the minute uneven portion 10 of the heated forming mold 11 from above to fill the molten resin 12 into the minute uneven portion 10 substantially in the same shape and thickness as those of a final shape of the molded product.
