PMMA surface hardness
Problem Phenomenon
PMMA products have many surface scratches during use
Cause Analysis
PMMA surface hardness is lower than glass, and daily contact easily produces scratches; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting
Solution
Apply surface hardening coating treatment; use a soft cloth for cleaning; add protective film to display parts; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Key Takeaway
PMMA scratch prevention relies on hardening coatings and usage management; 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 similar problems in the future
