PPS product dimensional accuracy
Sorun Belirtisi
Dimensional deviation of precision parts.
Neden Analizi
PPS low shrinkage and dimensional stability are advantages; but process fluctuations still affect accuracy.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Çözüm
①Stabilize mold temperature and holding pressure; ②measure actual shrinkage compensation; ③inspect after aging; ④SPC monitoring.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
PPS dimensional stability must be realized through process stability.; 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
