Abstract
Injection unit for an injection molding machine to process material, comprising a plasticizing cylinder, a screw, and a screw drive including two electric motors, such that the two motors have an electrically controlled connection to one another, to implement an injection and metering process, such that the two motors can be operated in the same or opposite direction of rotation and with the same or different rotational speed. A space is formed by at least two sleeves which can move relative to one another, and by respectively adjoining plate members, so as to take up lubricating oil, such that the sleeves can slide into one another, and the junctions of the parts which form the space are constructed tight against the environment, at least for lubricants.
