PPS glass fiber reinforced orientation warpage
Problembeschreibung
Directional warpage.
Ursachenanalyse
Fiber orientation anisotropy; superimposed by PPS high crystallinity.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Lösung
①Optimize gate for uniform orientation; ②uniform mold temperature; ③multi-point gates; ④low-warpage grade.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
Reinforced PPS warpage is the dual effect of orientation and crystallization.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
