Problem Phenomenon
PC/ABS nozzle temperature 245-260℃, matching the front section to prevent cold material.
Cause Analysis
PC/ABS nozzle temperature 245-260℃; matching the metering zone 240-255℃; cold material prevention and control; drool management; actual temperature measurement; start-up procedure.
Solution
①Nozzle 245-260℃; ②match the front section; ③cold material prevention and control; ④drool management; ⑤actual measurement verification.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PCABS nozzle temperature matching is a quality detail; cold material and drool are both important; actual measurement ensures accuracy.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
