1. A method for producing an injection molded part, which comprises the steps of:
injecting a plastic material into a cavity for forming the injection molded part, wherein the plastic material in a flow line region of the cavity, where the plastic material converges from two directions during an injection molding process, is at least partially removed from the cavity via at least two overflow points that are disposed tangentially and axially offset from one another and, during the injection molding process, is locally swirled or mixed between the at least two overflow points.
