TPU Nozzle Temperature
Sorun Belirtisi
TPU nozzle drooling alternates with cold slugs
Neden Analizi
The nozzle temperature window does not match the melt characteristics of TPU; when troubleshooting on site, verify item by item according to this mechanism to 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
Nozzle temperature consistent with the melt; screw retraction to suck back; needle valve nozzle; 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
Temel Çıkarım
Nozzle temperature matching plus suck-back prevents drooling; 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
