  • Patent number: 9011737
    Abstract: A system for making PET objects including a means for reacting a first PET precursor and a second PET precursor to produce a PET melt; a means for flowing the PET melt to a valve having at least two outlets; a means for flowing the PET melt from at least one of the at least two outlets to at least one die forming line and one pelletizing (cutter) line. A means for controlling individually the mass flow of the PET melt in each of the at least two system lines independently of the other and a means for forming the PET objects from the PET melt. The control scheme is a combination of a feed forward system as well as a feedback loop. The entire control scheme is part of the overall system PLC. The fine tuning of the pressure at the outlet of the die forming loop is controllers to less than +/?1 bar to obtain maximum control of formed part.

  • Publication number: 20150091200
    Abstract: This document describes techniques and apparatuses for smooth 3D printing using multi-stage filaments. These techniques are capable of creating smoother surfaces than many current techniques. In some cases, the techniques determine a portion of a surface of a 3D object that includes, or will include, a printing artifact or is otherwise not smooth, and then applies multi-stage filaments to provide a smoothing surface over that portion.

  • Publication number: 20150084222
    Abstract: An apparatus for forming an object by an additive process, commonly referred to as 3-D printing, is provided. The apparatus includes a filament comprising a series of irregularities along the length of the filament, a nozzle depositing a layer of melted material onto a surface and a feeder feeding the filament to the nozzle. A heating element melts the filament and a controller controls the position of the nozzle in a plane to control the configuration of the layer of melted material deposited by the nozzle. Additionally, a method for forming polymer filament used in 3-D printing devices is also provided. The method includes the steps of melting a polymer, selecting an extrusion characteristic calculated to induce a polymer flow instability and extruding the melted polymer using the selected extrusion characteristic to produce an extrusion having distortions created by the polymer flow instability.

  • Patent number: 8980146
    Abstract: A method and a machine that account for changes in material properties of molten plastic material during an injection run. If viscosity of the molten plastic material changes during an injection run, a controller alters an injection pressure to ensure that molten plastic material fills a mold cavity within a correct amount of time to prevent part flaws such as short shots or flashing.

  • Patent number: 8956559
    Abstract: According to a fabrication method, an extruded tubular member HA is formed, using an extrusion die 23 which has an extrusion orifice 25 having an opening-side inner circumferential surface 25a having a circular section and a core-side die 26 disposed concentrically with the extrusion orifice 25, by extruding a tube material through an extrusion passage 27 defined between the opening-side inner circumferential surface 25 and a core-side outer circumferential surface 26d of the core-side die 26. As this occurs, a bent configuration is given to the extruded tubular member HA by changing contact areas where the tube material contacts the opening-side inner circumferential surface 25a and the core-side outer circumferential surface 26d in a circumferential direction so as to set velocities at which the tube material is extruded to different values in the circumferential direction by controlling the position of the core die 26 in rotating and axial directions relative to the extrusion orifice 25.

  • Publication number: 20150042003
    Abstract: A method for injection molding of thermoplastic pole parts utilizes a mold to fix at least one vacuum interrupter and contact terminals during a molding process. At least one injection opening or gate for injection of thermoplastic material is formed into the mold. The mold is applied with multiple injection openings at least along its long axis, for injection of hot thermoplastic material, and the injection openings or gates can be steered in such a way that they inject thermoplastic material simultaneously or with a defined time dependent injection pattern. This process alleviates the issue of a pressure gradient along the long axis of the molded pole part, shortens process times, and achieves a homogenous dissipation of material during the molding process.

  • Patent number: 8940202
    Abstract: A method and apparatus of controlling commencement of an injection of a melt stream of moldable material from an auxiliary injection unit. A sensor is placed in an injection molding system to sense a condition related to an injection of a first melt stream of a first moldable material provided by a primary injection unit. Commencement of a second melt stream of a second moldable material from the auxiliary injection unit is initiated upon the sensed condition related to the injection of the first melt stream being detected at a preselected value. The sensed condition may be a pressure, velocity or temperature of the first melt stream as provided by a direct sensor, a force or strain on a hot runner component as provided by an indirect sensor or the occurrence of a function of the injection molding system as provided by a functional sensor.
