PETG raw material batch-to-batch flowability difference
Problembeschreibung
Different batches of PETG raw material have MFI differences, affecting filling consistency.
Ursachenanalyse
Fluctuations in the raw material production process cause different molecular weight distributions, inherent differences between batches.
Lösung
Establish an incoming inspection system; fine-tune the process according to batch differences; unify standards with the supplier.
Wichtigste Erkenntnis
PETG batch difference is a variable that needs continuous management in production.
