MODELING OF FLOW PHENOMENA ASSOCIATED WITH POLYMER INJECTION INTO A MOLD

Abstract

The process of plastic injection, although of extensive industrial use, is still relatively poorly researched. In building a finite element model for the injection process, the emphasis was laid on the modeling of phenomena occurring at the polymer-mold interface. With this purpose in mind, the mesh was refined in the vicinity of mold walls. The influence of the air present in the mold during the injection process was also taken into account. As the outcome of solving the problem so formulated, a model of polymer behavior at the mold wall interface has been obtained. Numerical simulations were carried out with the aid of a FIDAP flow-modeling program, and their results were partly verified by experimental means.
