ABS hot runner temperature
Fenómeno do problema
[Problem phenomenon] ABS hot runner gate defects, improper temperature control
Análise das causas
Hot runner temperature matched with the barrel at 230-260°C; local overheating causes degradation and low temperature causes cold material; sufficient preheating at startup; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Solução
Hot runner 230-260°C zoned closed loop; startup preheating; regularly check thermocouples; 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 hot runner 230-260°C, preheating and temperature control both emphasized; 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
