Abstract (English):
The problems of modeling the flow of polymers in channels with a small section in the overall production of about 2-3 cm3 are considered. The influence of channel dimensions on the thermosetting plastic movement in such channels is described. The arguments are given to prove necessity of careful control of the flow sections of small channels in the production of polymer products. A simulation of pressing a small product with the thermosetting plastic in a mold with a built-in filling element is carried out. The location of the filling element will allow to assess the nature of the flow front movement in the mold cavity most closely to reality. An attempt is made to analyze the influence of pressing conditions on obtaining a high-quality product and the behavior of the filling element in the mold cavity.
