LLDPE rotomolding cooling
ظاهرة المشكلة
Warpage and deformation of LLDPE rotomolded parts
تحليل الأسباب
Cooling too fast or uneven causes large shrinkage stress; when troubleshooting on site, verify item by item according to this mechanism to 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
الحل
Control cooling rate; uniform mold rotation; demold after setting; 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
Rotomolding cooling should be uniform and slow; after confirming effectiveness, fix 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
