LDPE First-piece Confirmation
ظاهرة المشكلة
Production starts immediately at startup, and the first batch film thickness is out of tolerance.
تحليل الأسباب
At startup, temperature and frost line have not stabilized; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; This mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting.
الحل
Stabilize for 15 minutes after startup; increase speed after thickness measurement passes; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; Change only one variable at a time and record parameter changes to facilitate locating effective measures.
الخلاصة الأساسية
After startup stabilization, measure thickness before increasing speed; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; Incorporate this case into the defect archive as a troubleshooting reference for similar future problems.
