Abstract

The paper considers the influence of the wall slip effect on the extrusion molding process when melting a polymer. The aim of this study is to develop a method for assessing the effect of wall slip in designing an extrusion forming tool.

The mathematical modelling of polymer melt flow in a channel was carried out taking into account the wall slip, the results of which were compared with the experimentally obtained dependencies, which allowed to find matching points. Using these points, the dependence of the velocity on the channel wall and the average integral velocity at the channel inlet was obtained. By approximating the resulting curve, an empirical equation was derived. It was the third degree polynomial which can be used for calculating the process parameters.

The study showed that taking into account the effect of wall slip had a significant impact on the process, which made it necessary to account for this parameter in the calculation of the extrusion moulding processes and in the design of processing equipment.

The results can be applied in the design of a forming tool and mathematical modelling of polymeric materials’ extrusion moulding processes.
