  • Patent number: 12179408
    Abstract: Ways for simultaneously forming and filling a container with a product are provided that include a mold cavity, a two-stage injection unit, and a blow nozzle. The mold cavity defines an internal surface and is configured to accept a preform. The two-stage injection unit receives and dispenses the product where a first stage includes an extruder and a second stage includes an accumulator. The extruder imparts mechanical energy to the product to reduce a viscosity of the product and transfers the reduced-viscosity product to the accumulator. The accumulator receives the reduced-viscosity product from the extruder and dispenses a charge of the reduced-viscosity product. The blow nozzle transfers the charge of the reduced-viscosity product dispensed from the accumulator into the preform to urge the preform to expand toward the internal surface of the mold cavity and form a resultant container.

  • Patent number: 12151417
    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.

  • Patent number: 11358327
    Abstract: The invention is directed to a method for additively manufacturing of a three-dimensional product using top-down stereolithography, wherein flowable, photopolymerizable material in a vat (50) is solidified in a locally selective manner by exposure from above, characterized in that a pressurized gas jet is directed to the surface of the photopolymerizable material, which pressurized gas jet is ejected by a pressurized gas nozzle of a blower (2) which is movable above the liquid level in the vat, wherein the pressurized gas jet is extensive in a direction transverse to the moving direction of the blower, and that by moving the blower with its pressurized gas nozzle across areas of the material surface to be solidify and acts on the surface in this manner, to smooth and level the surface. With such a method multi-component products may be built in which products a further component has to be built attached to an already existing component which (partially) protrude over the liquid level in the vat.
