В работе была использована программная система КОМПАС-3D для построения принципиальной схемы плоскощелевой головки. Для конструирования математической модели был использован программный комплекс ANSYS модуль Polyflow. Разработана математическая модель процесса экструзии термопластичных полимерных материалов через плоскощелевую экструзионную головку с коллекторами типа «рыбий хвост». Для оценки однородности распределения скорости расплава полимера по ширине формующего канала головки введен коэффициент качества распределения, характеризующий разброс значений выходных скоростей расплава по ширине формующего канала головки относительно среднего значения.</p></abstract><trans-abstract xml:lang="en"><p>Extrusion dies with flat slot exit cross-section are used for the production of products with a large width to thickness ratio, such as flat films, sheets, coatings. In the work, the KOMPAS-3D software system was used to construct a schematic diagram of a flat slot head. To construct a mathematical model, the ANSYS software package, the Polyflow module, was used. A mathematical model of the process of extrusion of thermoplastic polymeric materials through a flat-slot extrusion head with fishtail collectors has been developed. To assess the homogeneity of the distribution of the polymer melt velocity over the width of the forming channel of the head, a distribution quality factor was introduced that characterizes the spread of the values of output melt velocities along the width of the forming channel of the head relative to the average value</p></trans-abstract><kwd-group xml:lang="ru"><kwd>математическая модель</kwd><kwd>полимерный композит</kwd><kwd>экструзия</kwd><kwd>расплав</kwd><kwd>экструзионная головка</kwd><kwd>коэффициент консистенции</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mathematical model</kwd><kwd>polymer composite</kwd><kwd>extrusion</kwd><kwd>melt</kwd><kwd>extrusion head</kwd><kwd>consistency coefficient</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Younes B., Fotheringham A.
