PET vs PETG selection
Fenómeno do problema
Using PET instead of PETG for thick-walled transparent parts results in difficult molding and haze
Análise das causas
PETG is an amorphous copolyester with good thick-wall transparency and easy processing; PET's crystallization characteristics make thick-walled transparent parts prone to haze; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solução
Keep PETG for thick-walled transparent parts; use PET for thin-walled high-strength applications; the two are divided according to transparency and thickness requirements; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusão principal
PET and PETG are selected according to thickness and transparency requirements; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
