HDPE melt actual measurement
Problembeschreibung
With the same set temperature, the quality differs between batches
Ursachenanalyse
The actual melt temperature deviates from the setting, and HDPE is sensitive to temperature; when troubleshooting on site, 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 data and should be confirmed first during troubleshooting
Lösung
Regularly measure the air-shot melt temperature; correct the setting based on the actual measurement; record the correlation; 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
Wichtigste Erkenntnis
Quality consistency is based on the actual measured melt temperature; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar future problems
