HDPE winter raw material
Problem Phenomenon
The raw material temperature is low in winter, and the plasticization time is prolonged
Cause Analysis
The initial temperature of the raw material is low, melting energy consumption increases and plasticization slows down; 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
Solution
Preheat the raw material indoors in winter; fine-tune the barrel temperature; monitor the plasticization time; 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
Key Takeaway
Winter raw material preheating stabilizes plasticization; 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
