TPU Film Extrusion
ظاهرة المشكلة
TPU film extrusion has uneven thickness and many gel particles
تحليل الأسباب
Poor melt uniformity and possible unmelted particles; 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 literature and should be confirmed first during troubleshooting
الحل
Melt temperature guaranteed; denser filter screens; precise adjustment of die gap; 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
TPU film relies on melt quality and die precision; 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 problems in the future
