HDPE winter compensation
Sorun Belirtisi
HDPE products in winter are oversized and brittle
Neden Analizi
Too low cooling water temperature changes the crystallization mode, and the shrinkage and toughness of the product change; 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
Çözüm
Control the water temperature above 15℃ in winter; check the first piece dimensions and impact; fine-tune the process; 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
Temel Çıkarım
Winter water temperature lower limit management prevents brittleness and dimensional drift; 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
