MP Poor Plasticization
Problembeschreibung
Unmelted particles appear in MP products with incomplete plasticization
Ursachenanalyse
Screw compression ratio insufficient <2.5 and plasticization pressure low; screw rotation speed too low with insufficient shear; processing temperature too low
Lösung
1) Select a screw with compression ratio >3; 2) Increase screw rotation speed to increase shear; 3) Increase processing temperature by 5-10°C
Wichtigste Erkenntnis
Poor plasticization is caused by improper screw design; optimizing the screw and increasing temperature are key
