ViscoSensor

The ViscoSensor provides continuous measurements of the melt flow rate or apparent viscosity directly on the manufacturing process. The ViscoSensor system consists of two parts: a Viscosensor Rheologic Sensing Unit (RSU), connected directly to the process, and a Rheologic Control Unit that controls the ViscoSensor test parameters, provides outputs of computed results, and provides communications to an external distributed control system when required.

Importance of How Online Rheometers Accurately Indicate Melt Flow Rate in an Extruder

The present work aims to describe the design of the on-line rheometer and how it can be easily connected to the extruders using existing ports and flexible adapters. It also has been explained how the proposed on-line rheometer can duplicate the test conditions of an off-line melt flow rate tester on an extruder in any compounding or manufacturing process. Furthermore, through calculation of activation energy in a specific material and introducing a temperature correlation, it has been investigated how the on-line rheometer considers the temperature dependency of material`s MFR and accurately measures this parameter at various operating temperatures.

Simplified Rheology: A Technical Discussion

Understand technical aspects of how parameters change between laboratory standards and production and how advanced equipment today can adjust for these differences.

Detecting Polymers in Material ProductsIt can be very difficult, if not impossible, to achieve complete indentification of most polymer products. However, in most cases, this is usually not needed; what is needed is the separation, or identification, of numerous molding materials whose identity has been lost, or an indication of the type of material used to create a component.

Melt Processing of Thermoplastics for Extrusion and Injection Molding

Extrusion and injection molding are the most important conversion techniques used by the thermoplastics processing industry, Certain factors need to be considered before a thermoplastics material is processed, regardless of whether it is injection molding or extrusion molding that is used.
