LCP Backflow Mark Surface Defect
ظاهرة المشكلة
Cloud marks or flow-line-like streaks appear on the product surface along the flow direction.
تحليل الأسباب
LCP molecular orientation makes the surface extremely sensitive to flow patterns; unsteady filling or gate shear leaves orientation traces on the surface.; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based solely on experience
الحل
①Optimize gate form to reduce shear disturbance; ②steady filling speed curve; ③increase mold temperature to improve surface replication; ④evaluate mold polishing condition.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
الخلاصة الأساسية
LCP surface streaks are directly related to molecular orientation; steady filling and gate optimization are the main countermeasures.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
