On 14.02.2017 Janusz W. Sikora from Lublin University of Technology during the seminar Constructional methods of increasing the plasticating efficiency dedicated to the members of NEWEX project presented research results in the scope of technological and constructional issues concerning the increase of the efficiency of polymer extrusion processing. He pointed out the current technological solutions including changes in the screw speed and temperature distribution along the length of the plasticizing unit as well as constructional solutions including the screw and barrel design. He listed the geometrical elements of the screw and barrel which can be changed during the extrusion process. He presented a grooved feed section of the extruder, underlying its advantages and disadvantages as well as current constructional solutions which could be implemented into a new extruder.
