PCABS nozzle temperature anti-drool
Problembeschreibung
【Problem Phenomenon】PC/ABS nozzle drooling or cold material, improper temperature setting
Ursachenanalyse
Nozzle temperature slightly lower than the front section prevents drooling but cannot be too low to cause cold material; adjust in the 240-255℃ range according to the grade; drooling and cold material are the two ends of temperature; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
Lösung
Nozzle temperature 5-10℃ lower than the front section; lower 5℃ to verify for drooling; raise 5℃ to verify for cold material; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
PC/ABS nozzle temperature seeks balance, drooling and cold material each take a step back; after confirming effectiveness, fix 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 later
