ABS transparent grade process
ظاهرة المشكلة
[Problem phenomenon] Transparent ABS is cloudy or has flow lines, optical quality not up to standard
تحليل الأسباب
Transparent ABS is sensitive to moisture, impurities and shear; melt temperature 230-260°C and shear must be low; any degradation or stress manifests as optical defects; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
الحل
Transparent grade stricter drying; melt temperature mid-value and low shear; mold high polishing; recycled material prohibited; 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
ABS transparent grade clean and low shear, recycled material prohibited; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
