PET extrusion output fluctuation and surging
Sorun Belirtisi
PET extruder output fluctuates periodically, accompanied by pressure fluctuation and current swing.
Neden Analizi
Feed zone temperature too high, material melts prematurely and wraps the screw (bridging), screw design unsuitable for PET (improper compression ratio), poor feeding.
Çözüm
Reduce feed zone temperature (water cooling 60-80°C); use PET dedicated screw (compression ratio 2.5-3.0:1); check feeding.
Temel Çıkarım
PET extrusion surging is often caused by feed zone problems; screw design and temperature control are fundamental.
