    摘要: A molding method in an injection-compression molding machine provided with an opening/closing valve between an injection unit and a metal mold, in which in order to make a density of molten resin uniform for resulting in production of stable molded articles, before the molten resin is injected into the metal mold, the aforementioned valve is closed to carry out preliminary pressing within the injection unit, and thereafter pressing on the molten resin is carried out within the metal mold during injection or after injection, as well as a molding apparatus for achieving the above-mentioned method. This molding apparatus includes the valve (40) disposed so as to be freely opened and closed in the flow passageway (46) of the molten resin provided between the injection unit (10) and the metal mold (30) for effecting blocking or change of a cross-section area of the above-mentioned flow passageway.
