LDPE Melt Actual Measurement
Fenómeno do problema
With the same set temperature, film quality fluctuates.
Análise das causas
Actual melt temperature deviates from the set value; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; This mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting.
Solução
Regularly measure actual melt temperature; correct settings based on actual measurements; 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
Film quality is based on the measured melt temperature; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; Incorporate this case into the defect archive as a troubleshooting reference for similar future problems.
