PAEK insufficient mold filling flow
Problembeschreibung
Thin-wall cavity underfilled
Ursachenanalyse
Processing temperature <350°C, near the melting point the melt viscosity is extremely high; mold temperature low and the melt solidifies quickly
Lösung
Increase the melt temperature to 370-390°C; keep the mold temperature at 180-200°C
Wichtigste Erkenntnis
PAEK requires a processing temperature sufficiently above Tm to ensure flowability
