Melt breakage during extrusion
Fenómeno del problema
Melt breakage during extrusion, the product cannot be continuously formed, production interrupted
Análisis de la causa
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
Solución
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
Conclusión clave
Extrusion breakage requires increasing temperature and ensuring continuous plasticization
