EVOH Length Out of Tolerance
Problembeschreibung
EVOH product length deviation >±0.5mm, out of tolerance
Ursachenanalyse
EVOH shrinkage unstable fluctuating ±0.5%; mold dimension design did not consider shrinkage compensation; cooling insufficient, dimensions not stabilized
Lösung
1) Precisely measure EVOH shrinkage and compensate the mold; 2) Fully cool to ensure dimensional stability; 3) Annealing to eliminate post-shrinkage
Wichtigste Erkenntnis
Length out of tolerance is caused by unstable shrinkage; precise shrinkage compensation is key
