HDPE Sink Mark
ظاهرة المشكلة
HDPE thick-wall product surface sink marks
تحليل الأسباب
Thick-wall shrinkage compensation is insufficient, and HDPE large crystallization shrinkage makes sink marks obvious; 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
Increase holding pressure and time; uniform wall thickness; enlarge the 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
HDPE sink marks rely on holding pressure and wall thickness design; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
