摘要： The present invention provides an injection molding method which intends to lower a mold clamping force in view of both of a projected area of a molded article and an injection pressure, and contributes to an energy saving and a reduction in a cost of equipment and a manufacturing cost. In a cavity (13) formed in a metal mold (5) for an injection molding, there are arranged a first gate (21) injecting a first molten resin (101) anteceding in one end side (a charging start side) in a longitudinal direction, and a second gate (22) injecting a second molten resin (102) following in another end side (a charging finish side). The second molten resin (102) is newly injected from the second gate (22) before a fluid head portion of the first molten resin (101) injected from the first gate (21) reaches a position of the second gate (22). Further, the first molten resin (101) becomes in an approximately cooled and solidified state by the time when the second molten resin (102) reaches a terminal end in the charging finish side within the cavity (13).

摘要： An injection molding apparatus used comprises a molten resin injector 15 for injecting a molten resin, and a die 12 connected to the molten resin injector and communicating with the molten resin injector so that the molten resin is injected into the die. A cavity having a prescribed shape is formed within the die in order to mold the injected molten resin into the prescribed shape. An opening of the die for guiding the molten resin to the outside is blocked so as to confine a molding object as an object for molding the resin member. A plate member 10 as a molding object is compressed onto the die 12, and the molten resin is injected into the die while compressing the molding object. The molten resin is adhered on the molding object by being guided from the opening, and a solidified resin member comprising the solidified molten resin is bonded on the surface of the molding object. Consequently, the resin member having a prescribed shape is readily and promptly formed on the surface of the molding object.
