For simulation of thin-wall injection molding, accurate viscosity data measured at shear rates up to 800,000 s−1 and more are important, but not available in any commercial material database. Such data can be measured on conventional injection mold

This study is concerned with the flow behaviour of a rubber compound in capillary and injection moulding dies in the temperature range of 80–120°C. The injection moulding die designs had a tapered ...

In this study, polymer nanocomposites (PNCs) based on polypropylene (PP), organoclay (used as nanoclay), and compatibilizer were prepared by a masterbatch (MB or two-step) as well as by a one-step process. These compounds were then injection molded i

This paper focuses on the measurement of elongational viscosity of polymer melts and filled compounds using a novel online rheometer. We developed a device with two slit sections and a hyperbolic contraction part in between, which allows for constant

The bulk temperature is a very important parameter for the processing of rubber compounds. Currently, standard injection molding simulation is taking into account just shear heating, while elongational heating is neglected by most available software

Polymer processing is typically done via the melt state. Plastic pellets are conveyed with a screw, melted, transformed into the desired shape and finally cooled down to ambient temperature. From this process chain, several simulation targets can be

The paper presents an overview of the tape-laying process for thermoplastic matrix composites and the current state-of-the-art simulation of this process. As the current mathematical description of the process is partly based on a Newtonian shear flo
