Florian Bittner | IKK
Manufacturer: KraussMaffei Extrusion GmbH
Short description: Modular recycling line consisting of various interacting individual units, a melting extruder and a compounding extruder with various options for adding a wide range of fillers, reinforcing and recycling materials as well as extensive inline and online analysis equipment (color, viscosity, odor, etc.).
Application: Development and adaptation of high-quality recycling processes with more complex input flows, product-specific recipe development and process optimization. Recipe development/recycling/process optimization/process analysis in R&D.
