PETG product thermal history imprint gloss difference
Problembeschreibung
Different surface areas have different light reflectivity, forming visible gloss differences.
Ursachenanalyse
Surface microstructures in areas with different thermal histories differ, causing reflection differences; the difference between the gate area and the end area is obvious.
Lösung
Balance the mold temperature; uniform product wall thickness; optimize gate position.
Wichtigste Erkenntnis
PETG gloss difference is a reflection of molding thermal history.
