Method for continuously manufacturing optical article |
摘要 |
There is provided a method for continuously manufacturing an optical article which comprises a first step of thermal press-molding a sheet-like curved body and a second step of insert injection-molding a back resin on a concave side of the sheet-like curved body, while transferring the continuous sheet in a longitudinal direction, using an apparatus for manufacturing an optical article in which a press-molding machine which can thermal press-mold the sheet-like curved body and an insert injection-molding machine equipped with a mold having a curvature similar to that of the sheet-like curved body are serially positioned in this order, wherein a cycle of thermal press-molding and a cycle of insert injection-molding are synchronized to continuously insert-mold the back resin on a concave side of the sheet-like curved body while continuously thermal press-molding the sheet-like curved body. |
