    Abstract: A gas assisted molding apparatus having gas introduced into the plastic charge as the charge is flowing into the mold cavity. The gas and plastic are simultaneously injected into the mold cavity and the gas can be introduced at the nozzle end or barrel of the injection molding machine. Optionally, the gas may be injected into a hot runner manifold or into the cavity itself simultaneously with the plastic. The apparatus includes a conventional gas injection mold, a source of inert gas, such as nitrogen, and an injection assembly. A common power source is used for both the injection of the plastic and the gas to assure simultaneous inflow of both the gas and the molten plastic at the same pressure.
