Zusammenfassung:

Compared to most consumer goods, the lifetime of capital goods and plastics machinery/ compounding plants in particular is factors or even powers longer. It is quite likely that the plants are in operation for decades. Therefore, adaptability to changing or new requirements is of great importance. This paper presents multiple approaches, analytic processes and instruments, and their use based on concrete examples and scenarios.

Abstract

There is no all-round compounder. No individual extruder can handle equally well all the challenges posed in practice. Key for specific compounding tasks are often the individual steps, such as feeding of poorly flowing or very high-volume additives, efficient melt degassing, or particularly gentle plasticization of sensitive plastic compounds. So which extruder is best for the task in hand? Alternatively, which extruder can flexibly handle the widest range of compounding applications cost-effectively? Moreover, when is a customized solution the best? A brief introduction in evaluation methodologies are given and illustrated with practical examples.
