During the Workshoop on 14.02.2017 within T 5.1a, Mr Łukasz Majewski from Lublin University of Technology gave a lecture Kinematic activation of the barrel. During his presentation he showed that there are currently many modern methods of polymer processing and also a lot of unconventional construction designs of polymer processing machines. One of the many aspects of designers’ interest is the construction of the barrel of the plasticizing system. Łukasz Majewski showed the possibility of the kinematic activation of the barrel by placement of the rotary sleeve in selected heating zones of the plasticizing system. The outline of the rotating sleeve structure was described, including known construction variations such as grooves geometry and rotation direction. On the basis of the conducted research, the influence of the counter-rotating sleeve location and rotational speed on the extrusion process efficiency was shown. He also discussed the changes of the selected process parameters such as temperature of the barrel wall, polymer pressure, mass flow rate of the polymer and specific total energy consumption. Studies of the selected properties of the extrudates were also presented, to determine the influence of the rotating barrel sleeve on the polymer basic properties.
