This work follows the general framework of polymer injection moulding simulation whose objectives are the mastering of the injection moulding process. The models of numerical simulation make it possible to predict the propagation of the molten polymer during the filling phase from the positioning of one point of injection or more. The objective of this paper is to propose a particular way to op...

Tools for injection molding are very expensive parts of this kind of production and they must be handled very carefully. An important part of their handling is the management of data related to the tools. The important data for injection molding tools is possible divide to different areas economical, technological, production etc. With an increasing impact of information technologies on manufac...

We numerically investigate the stability problem of the injection molding process. It was indicated by Bulters and Schepens Bulters and Schepens 2000 that surface defects of injection molded products may be attributed to a flow instability near the free surface during the filling stage of the mold. We examine the stability of this flow using the extended Pom–Pom constitutive equations. The mode...
