Solution
Optimize demolding and clamping contact surfaces; products separated and protected; high-appearance parts surface film protection; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
ASA fears scratches, flow protection and film are appearance guarantee; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
