Off-line re-pelletising systems for thermo-plastic plastics

Our special screw geometry makes it possible to process even extremely light feed materials without pre-compaction or thermal pretreatment. As a result, there is no thermal and oxidative preloading of the feed material in our systems, e.g. by agglomerators or cutting compressors, which is noticeable in the achievable granulate quality.
