POM Silver Streak
Sorun Belirtisi
Radial silver streaks on POM part surfaces
Neden Analizi
Caused by moisture or shear heat; POM is sensitive to shear; 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
Çözüm
Verify by drying first; if not eliminated, reduce injection speed and back pressure; 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
Temel Çıkarım
For POM silver streaks, troubleshoot moisture first then shear; 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
