Abstract
Gas injection molding machine. A gas injection molding machine provided with an auxiliary cavity formed in one side of a cavity to allow the molten resin to be nebulized and expelled from the cavity by injecting gas through a door, the auxiliary cavity having a means of control to freely change an area of the same in order to house the resin to be nebulized during the injection of the gas, thus avoiding the formation of defects on the external surface of the molded product and avoiding the inconvenience of additional finishes of the molded product after gas injection.
