POM Printing Ink Loss
ظاهرة المشكلة
Silk-screen printed marks on POM parts wipe off easily
تحليل الأسباب
Low surface energy causes poor ink wetting and anchoring; 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
الحل
Corona or flame treatment before printing; use POM-specific ink; verify curing after printing; after adjustment, take continuous samples 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
الخلاصة الأساسية
POM printing requires surface activation plus special ink; after confirming effectiveness, solidify 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
