PC transparent grade process
Sorun Belirtisi
【Problem Phenomenon】Transparent PC is turbid or has flow marks, optics not up to standard
Neden Analizi
Transparent PC is extremely sensitive to moisture, shear, and stress; melt temperature 290-310℃ with low shear; any degradation or stress manifests as optical defects；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Çözüm
Transparent grade drying tightened; low shear; mold high polishing; regrind prohibited；After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability；Change only one variable at a time and record parameter changes to facilitate locating effective measures
Temel Çıkarım
PC transparent grade clean and low shear, regrind prohibited；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence；Include this case in the defect archive as a reference for troubleshooting similar problems in the future
