POE surface periodic corrugation
Problembeschreibung
POE product surface periodic corrugation, spacing 5-15mm
Ursachenanalyse
Injection speed periodic fluctuation; hydraulic system unstable; screw speed unstable
Lösung
1) Overhaul injection system to stabilize pressure and speed; 2) Servo motor drive replacing hydraulic drive; 3) PID control to stabilize injection parameters
Wichtigste Erkenntnis
Corrugation is caused by injection instability; equipment overhaul and PID control are key
