ABS barrel zone temperature
Fenómeno do problema
[Problem phenomenon] ABS barrel temperature settings jump, causing uneven plasticization or local overheating
Análise das causas
ABS recommends progressive zoning: rear zone 180-210°C, middle zone 210-230°C, front zone 230-250°C, nozzle 240-260°C; reasonable zoning ensures uniform plasticization and prevents degradation
Solução
Set each zone according to the progressive curve; nozzle slightly lower than front zone to prevent drooling; actual melt temperature calibration; 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
Conclusão principal
ABS barrel progressive temperature increase, nozzle slightly lower to prevent drooling; 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 subsequent similar problems
