PC Transparent Part Optical Standards
Sorun Belirtisi
The light transmittance of optical lenses and lamp covers fluctuates, and the color difference and haze exceed the standard between different batches
Neden Analizi
PC light transmittance is about 88-90%, lower than PMMA's 92%, and is more sensitive to process fluctuations; slight changes in melt temperature, mold temperature and moisture content are all reflected in the optical performance
Çözüm
①Dedicated batch management of optical-grade raw materials; ②dehumidification drying at 110-120°C×4-6h; ③establish a first-piece inspection system for light transmittance and haze, with process parameters locked
Temel Çıkarım
Optical-grade PC is the highest standard of process control; parameter locking plus first-piece optical inspection eliminates fluctuations before mass production; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
