Periodic EMA surface ripples
Problembeschreibung
Periodic ripples with 5-15mm spacing on EMA product surface
Ursachenanalyse
Injection speed fluctuates periodically; 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
Ripples are caused by unstable injection; equipment overhaul and PID control are key
