PETG injection molded part surface scratches
문제 현상
PETG transparent product surfaces are prone to scratches, and transparency and appearance are affected.
원인 분석
PETG surface hardness is low (pencil hardness HB-F), contact with hard objects during handling, and scratching during mold opening/closing and ejection.
해결 방법
Use UV-curable hard coating to increase hardness; optimize mold opening/closing and demolding actions; use protective film for product packaging.
핵심 요약
PETG poor surface scratch resistance is its application shortcoming, requiring coating protection.
