PURPOSE:To obtain a window glass for vehicle having excellent durability, high performance and pretty appearance in high productivity, efficiently and at a low cost, by carrying out at least one injection molding of multi-colored molding by utilizing an injection compression molding. CONSTITUTION:A molded item of a thin thickness and on which a molding pressure is uniformly applied can be obtained by applying compression on a resin 20 injected from a nozzle 21a in metal molds 21 and 22 before it is cooled and solidified. When the molded item is relatively small, a molding method where the resin is filled into the end corner of the mold while the compression allowance of 5-10% of the thickness of the molded item is kept as an allowance for compression, is preferable. On the other hand, when the molded item is relatively large, as it becomes hard that the resin will flow sufficiently in the mold, it is preferable that a method where a part for compression allowance d is taken largely in advance against the thickness D of the molded item is applied. |
