TPU cable sheath bubbles
Problembeschreibung
Bubbles appear inside the extruded cable sheath.
Ursachenanalyse
Insufficient pellet drying causes moisture vaporization; extrusion temperature fluctuations also produce bubbles; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry materials and should be confirmed first during troubleshooting
Lösung
①strengthen drying management; ②stabilize extrusion temperature; ③optimize head pressure; ④test sheath compactness; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
Cable sheath bubbles affect insulation performance; drying and temperature stability are the quality foundation; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
