A rotational drive of the drive unit is controlled such that a speed of the plasticising screw causes overlay of a backflow of the plastic melt from the screw antechamber back into screw threads of the plasticising screw by an opposing delivery flow as a result of a rotation of the plasticising screw due to a translational injection movement of the plasticising screw. A differential flow is established from the backflow and the opposing delivery flow and influenced at least during the injection phase by influencing the speed of the plasticising screw.

  • Patent number: 10974460
    Abstract: Tracking of measured depth with intervening depositing of one or more layers provides a way of improving the accuracy of surface reconstruction. For example, knowledge of the desired or expected thickness of each layer, in combination with the scan data is combined to yield higher accuracy than is available from scan data of a single scan alone. One application of such an accurate surface reconstruction is in a feedback arrangement in which the desired thickness of one or more subsequent layers to be deposited after scanning is determined from the estimate of the surface depth and a model of the object that is being fabricated, and by increasing accuracy of the surface depth estimate, the precision of the fabrication of the object may be increased.

  • Patent number: 10960591
    Abstract: A method for carrying out a cyclical manufacturing process produces parts within a predefined quality tolerance. After at least one process adjustment variable is changed, a quality feature of the parts produced with a changed process adjustment variable is checked against the range of the quality tolerance of the produced parts. A process characteristic variable zone is formed in an automated manner using at least one determined process characteristic variable variant that is process-stable and for which the process adjustment variable produces acceptable parts.

  • Patent number: 10946551
    Abstract: In-line inspection and control system to in-situ monitor an extrudate during extrusion. A light beam illuminates a line on the outside circumference of the extrudate skin recording the curvature. A master profile of the illuminated defect-free skin is recorded and compared to successive monitoring of the illuminated skin. Differences from the comparison indicate skin and/or shape defects. A real-time feedback to automatically adjust process control hardware reduces or eliminates the skin and shape defects based on the monitoring and comparison.

    Abstract: Systems and methods are provided for use with a thermoplastic road marking system (e.g., paint truck). The systems and methods control an insertion or replenishment rate of unmelted thermoplastic paint feed stock into a thermoplastic melter based, at least in part, on the rate that thermoplastic melt is being applied to a marking surface. By substantially matching the replenishment rate into the thermoplastic melter with the application rate, thermal variance within the thermoplastic melter is reduced, which improves the consistency of marking lines applied to surfaces.
