PA6 Printing Ink Loss
Sorun Belirtisi
The silk-screen printed marking on PA6 product surfaces loses ink after rubbing
Neden Analizi
PA6 surface polarity makes ordinary ink adhesion mediocre, and release agent residue and surface crystallization state affect ink wetting and anchoring; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based only on experience
Çözüm
Clean the surface before printing and perform corona or flame treatment; select nylon-specific ink and fully cure it; verify by abrasion test after printing; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
PA6 printing requires special ink plus surface treatment to ensure adhesion; 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 similar problems in the future
