Melt breakage during extrusion
ظاهرة المشكلة
Melt breakage during extrusion, the product cannot be continuously formed, production interrupted
تحليل الأسباب
Extrusion temperature too low (below the lower limit of 170-230°C), insufficient melt strength
Poor screw plasticization, discontinuous melt
Raw material moisture content exceeds standard
Screen pack blocked
Haul-off speed too fast, tensile breakage
الحل
Increase the extrusion temperature to the 170-230°C range
Ensure continuous screw plasticization
Fully dry the raw material
Replace the screen pack
Appropriately reduce the haul-off speed
الخلاصة الأساسية
Extrusion breakage requires increasing temperature and ensuring continuous plasticization
