PETG injection molded part surface scratches
Fenómeno do problema
PETG transparent product surfaces are prone to scratches, and transparency and appearance are affected.
Análise das causas
PETG surface hardness is low (pencil hardness HB-F), contact with hard objects during handling, and scratching during mold opening/closing and ejection.
Solução
Use UV-curable hard coating to increase hardness; optimize mold opening/closing and demolding actions; use protective film for product packaging.
Conclusão principal
PETG poor surface scratch resistance is its application shortcoming, requiring coating protection.
