PC Silver Streaks Reappearing After Post-Processing
Sorun Belirtisi
PC parts develop fine cracks after machining or polishing.
Neden Analizi
Internal stress is released after mechanical processing removes the surface constraint, superimposed with processing heat and tool stress to induce cracks.
Çözüm
①Reduce '2079851475616104452 residual stress (low holding pressure, high mold temperature); ②Anneal before processing; ③Use sharp tools, small feed, and sufficient cooling for processing.
Temel Çıkarım
Reduce internal stress first, then machine.
