ABSTRACT:
In an injection molding method to manufacture hollow plastic parts, at least one plastic part's hollow is shaped by evacuating an internal portion of the flowable material of an injection mold's cavity using a pressurized gas, and a gate of the mold and thereupon the molded article's aperture so made will be sealed off. After the flowable material has been moved from a blind duct into the gate and partly forced back into the hollow, the molded article will be ejected from the injection mold.
