PETG product thermal history imprint gloss difference
문제 현상
Different surface areas have different light reflectivity, forming visible gloss differences.
원인 분석
Surface microstructures in areas with different thermal histories differ, causing reflection differences; the difference between the gate area and the end area is obvious.
해결 방법
Balance the mold temperature; uniform product wall thickness; optimize gate position.
핵심 요약
PETG gloss difference is a reflection of molding thermal history.
