A plasticizing unit includes an injection cylinder having a dispensing opening, via which a plasticized material can be dispensed, and a plasticizing screw arranged to be rotationally and linearly movable in the injection cylinder and having an axis of rotation. A plasticizing zone is formed between the plasticizing screw and the injection cylinder in the radial direction relative to the axis of rotation of the plasticizing screw. The plasticizing screw has a dam element, and in the injection cylinder there is a first opening in the area of the plasticizing zone and/or the dam element and a second opening between the dam element and the dispensing opening.
