LLDPE Short Shot
ظاهرة المشكلة
LLDPE thin-walled parts are incompletely filled
تحليل الأسباب
LLDPE flowability is average, making thin-wall filling difficult; During on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based solely on experience; This mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
الحل
Take the upper limits of melt temperature and mold temperature; increase speed; enlarge gate; 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
الخلاصة الأساسية
Thin-wall short shot relies on temperature and speed; 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 subsequent similar problems
