    Abstract: A system and method for calibrating the gap between a 3D printer extruder nozzle and build platform are disclosed. To calibrate, the build platform is moved laterally in the horizontal plane and the extruder nozzle is moved downward toward the build platform. While moving the nozzle downward, the velocity of the build platform or the power required to move the build platform in the horizontal plane is monitored. A drop in velocity or an increase is power required to move the build platform is detected when the extruder nozzle contacts the build platform due to kinetic friction. The vertical height of the extruder nozzle is then set or calibrated relative to the build platform based on the position of the extruder nozzle when the contact was detected.

    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.

  • Publication number: 20140306365
    Abstract: Methods and systems for co-extruding multiple polymeric material flow streams into a mold having a plurality of cavities to produce a plurality of multi-layer polymeric articles each having a consistent coverage of an interior core layer are disclosed herein. In an example method, a flow rate of a first skin material into a cavity is individually controlled for each cavity before initiation of co-injection of a second core material into the cavity, which may address inconsistent interior core layer coverage for articles from different cavities.

    Abstract: A method of forming an oral product includes extruding a mixture, conveying the extruded mixture through one or more pairs of forming rollers, and cutting the extruded mixture into one or more oral products. The mixture can include polymer and at least one flavorant, sweetener, active ingredient, or combination thereof. The extruded mixture forms an extrudate having a predetermined cross-sectional shape. The one or more pairs of forming rollers abut to define a passage there between as each forming roller rotates. The passage has a cross-sectional shape corresponding to the predetermined cross-sectional shape. The method can be performed using a machine including an extruder, one or more pairs of forming rollers, and a cutting device.

  • Publication number: 20140191433
    Abstract: In a method for discharging a volume flow consisting of successive drops to produce a three-dimensional object of solidifiable material present in a fluid phase, the fluid phase of the material is introduced into a material storage means. A pressure (p) is applied to the fluid phase, in order to discharge the material in drops out of a cyclable outlet opening to build up the three-dimensional object in a construction chamber. A method is provided for achieving a constant, discontinuous volume flow by the pressure (p) being regulated via a closed-loop control in the event of a change in the viscosity of the fluid phase of the material, while maintaining the other process parameters, to achieve a predetermined drop size. The pressure is applied by a conveying element, the average displacement velocity of the conveying element per discharged drop being converted as a measured variable into the control variable for the closed-loop control.
