COC production quality control, optical and dimensional standards.
Cause Analysis
COC quality control; optical performance; dimensional accuracy; appearance defects; inspection standards; data management.; During on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Solution
①Inspection standards; ②optical management; ③dimensional control; ④appearance inspection; ⑤data analysis.; After adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
Optics and dimensions are the core of COC quality control; standards are the foundation; data drives improvement.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
