PMMA Regrind Limitation
Sorun Belirtisi
After mixing regrind, optical quality of transparent parts decreases, and gel particles and impurities increase
Neden Analizi
Even if PMMA regrind is glass-transparent, optically qualified products usually cannot be obtained; thermal history and trace contamination make transparency and purity unrecoverable; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Çözüm
①Prohibit regrind in optical transparent parts; ②opaque colored parts can reuse it after thorough drying; ③limit regrind ratio according to product grade; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
PMMA regrind and optical quality cannot be achieved together; zero regrind for transparent parts is an industry rule; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
