PVB Quality Traceability
Problem Phenomenon
PVB quality problems are difficult to trace, batch and process data incomplete.
Cause Analysis
PVB production data recording; batch management; raw material traceability; process parameters; quality correlation.; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based solely on experience
Solution
①Full-process batch recording; ②Raw material traceability system; ③Process parameter archiving; ④Quality data analysis.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PVB quality traceability is the basis for improvement; data integrity is key; analysis drives prevention.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
