More Information
Summary:A method of influencing a backpressure length and/or a screw return speed in an axially extending plasticizing cylinder of a plasticizing unit for an injection moulding machine including a plasticizing screw arranged displaceably and rotatably in a cylinder bore of the plasticizing cylinder. Metering of plastic granulate fed to the plasticizing unit is carried out in dependence on the desired backpressure length in the plasticizing unit, and the plasticizing unit is operated in underfed mode.
