SMMA Melt Temperature Management
Fenómeno do problema
SMMA melt temperature deviates from the barrel setting, with the 200-240℃ standard not met or exceeded.
Análise das causas
SMMA melt temperature standard 200-240℃; difference between barrel setting and actual measurement; influence of temperature measurement method; melt uniformity; grade differences.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Solução
①Actually measure melt temperature 200-240℃; ②standardize the temperature measurement method; ③verify uniformity; ④differentiate by grade.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusão principal
SMMA melt temperature actual measurement is the process benchmark; 200-240℃ is the standard range; standardized temperature measurement keeps data credible.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
