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