POM Printing and Bonding Difficulty
Problembeschreibung
POM parts lose ink in printing and debond in adhesion; surface treatment effects are not durable
Ursachenanalyse
POM has low surface energy, making it difficult for inks and adhesives to wet and adhere; after surface treatment, activity decays over time, and too long an interval from treatment to processing makes it ineffective; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Lösung
①Corona or plasma treatment before printing and bonding; ②complete printing and bonding as soon as possible after treatment; ③select special inks and adhesives for low surface energy; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
The timeliness of POM surface treatment is key; process immediately after treatment, and only with special consumables can adhesion be durable; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
