Four-Dimensional Troubleshooting of LCP '2079851475616104452 Bubbles
ظاهرة المشكلة
【Problem Phenomenon】Bubbles repeatedly appear inside or on the surface of LCP products, and single machine adjustment cannot cure them
تحليل الأسباب
Bubble causes are divided into four categories: poor mold venting, insufficient '2079851475616104451, degradation from too high molding temperature, and excessive machine shear; Aibang literature proposes the mold/material/molding conditions/machine four-dimensional troubleshooting method
الحل
Troubleshoot in the four-dimensional order: first measure drying and dew point, then verify the actual melt temperature, then check venting and gate, and finally evaluate screw shear and back pressure; after verifying item by item to locate the main cause, solidify the parameters
الخلاصة الأساسية
For LCP bubbles, use the mold-material-process-machine four-dimensional method to eliminate item by item; avoid changing multiple things at once; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
