Understanding rheology can help processors use viscosity curves to troubleshoot extrusion and injection molding problems
Rheology is the branch of physics dealing with the flow of matter. While most extrusion and injection molding equipment designers are very familiar with the information rheology provides, many processors don’t understand the science behind it. Rheology can help you understand shear thinning, melt temperature, and thermal degradation. For example, learning to read a viscosity curve helps you understand the flow distribution from an extrusion die as well as the melt pressure through a die and at the tip of a screw. 
 
This tutorial on rheology helps processors understand viscosity curves and how to use them to solve problems related to sheer thinning, controlling the melt temperature, establishing a stable/unstable flow processing window for a material, and troubleshooting melt-flow instabilities.
