Polymer Melt Viscosity Measuring by An Injection Machine

In my article I would like to present a special measurement procedure of polymer melt viscosity measurement. The general idea is based on the capillary viscometer measuring technique, but It is closer to the production process' variable conditions, for example the change in melt cross section, melt temperature increase with the shear stress and the melt pressures. An injection machine is able to measure and regulate the filling process pressure, speed and temperatures so, everything is given for a viscosity measurement, Of course It is not a standard measuring process, but it may be very interesting to compare the results with the standard measuring tools results. In the end I illustrate the results of the standard and non standard procedures in one diagram. The flow curves show a wide range of shear rate, temperature, and shear stress
