  • Patent number: 11897211
    Abstract: Disclosed herein is a method and apparatus for automatic extrudate loading and alignment. An extrudate handling system includes a head end assembly and an imaging device (which may be part of the head end assembly). The imaging device is configured to image an end face of an extrudate, and generate, during translation of the extrudate, an imaging output signal indicative of a rotational position of the end face of the extrudate. The head end assembly includes a rotational effector to rotate the extrudate during translation thereof and a fixed effector rotationally fixed relative to a track. The extrudate handling system is able to determine the rotational position of the web angle of the extrudate and precisely adjust the rotational position while linearly translating the extrudate along the track. The extrudate handling system provides greater accuracy, reduced costs, and improved results.

  • Patent number: 11813789
    Abstract: The present invention provides a method for altering the bead profile for using 3D printing to improve the shear strength of a so manufactured product by altering the bead height of adjacent beads or in adjacent layers such that either the height or the centers of the beads between adjacent layers are altered. This is achieved by either height reduction or by flow rates to alter the height or positioning of the beads by altering the bead profiles the shear strength between adjacent layers in the X-Y plane is improved. The present invention is equally applicable to increasing shear strength in the Y-Z plane or the X-Z plane as desired.

  • Patent number: 11808520
    Abstract: The invention relates to an arrangement of a furnace and of bulk material of glass particles, said furnace (10) comprising a pressing punch (36), a pressure, distance and/or speed sensor and a control device for controlling a pressing process based on the output signal of the sensor. The sensor detects at least a pressure, position and/or motion parameter of the pressing punch (36). The pressing punch (36) acts on the bulk material of glass particles (32)—possibly via an interposed ram (28)—, said glass particles being guided and crystallizable in a press channel (30). The trigger criterion for the process control is a change of at least a motion parameter of the pressing punch (36) upon softening of the bulk material of glass particles (32) which change is detected by the sensor.

  • Patent number: 11370029
    Abstract: The disclosure provides a method of additive manufacturing a three-dimensional object, which can prevent a blade from being caught by a deformed part that is generated due to an unpredictable change of a sintering condition. In the method of additive manufacturing the three-dimensional object, if a deformed part having any height is generated on the upper surface of the nth sintered layer, when the next n+1th sintered layer is formed, the n+1th powder layer is irradiated with laser by avoiding the region where the deformed part is generated. Then, after the n+2th powder layer is formed, the unsintered part is sintered together with the n+2th powder layer.

  • Patent number: 11360053
    Abstract: Non-destructive evaluation (NDE) systems and methods are provided for monitoring objects being manufactured during a cure or consolidation process and for detecting defects that occur during the cure or consolidation process or to detect conditions of the process that can lead to the occurrence of defects. Information acquired by the NDE system during the cure or consolidation process can be used to adjust one or more parameters of the process in real-time to prevent defects from occurring or to reduce the number and/or severity of defects that occur during the cure or consolidation process.

  • Patent number: 11358317
    Abstract: In order to improve the consistency of molded products as viscosity shifts throughout a run, a controller of an injection molding machine executes a calibration cycle in accordance with a mold cycle. The controller analyzes a plurality of sensed melt pressure values during the calibration cycle to determine one or more calibration metrics. The controller then uses the calibration metrics when executing each mold cycle of the run. More particularly, during each mold cycle of the run, the controller detects a plurality of sensed melt pressures prior to and during a fill phase of the mold cycle and compares the plurality of sensed melt pressures to the one or more calibration metrics to predict cavity pressure for a pack and hold phase of the mold cycle. The controller then adjusts a set point pressure for the pack and hold phase based on the predicted cavity pressure.
