https://ikv-aachen.de/wp-content/uploads/2026/04/IGF-23114-N-scaled.jpg2560988To record wall slip effects in the rubber extrusion process, continuous measurement of pressure or wall shear stress is required. In the ‘Extrusion Rheometer’ research project, a combination of innovative extrusion rheometers was developed for this purpose, which can be used to measure both the local pressure at every point of the rheometer as well as the wall shear stress within the flow.
