PCABS Cold Slug Marks
ظاهرة المشكلة
[Problem Phenomenon] PC/ABS surface cold slug marks, with disordered front-stage filling
تحليل الأسباب
Low nozzle temperature or insufficient cold slug well; cold material of amorphous materials is difficult to re-fuse; 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 data and should be confirmed first during troubleshooting
الحل
Match nozzle temperature to the front stage; enlarge the cold slug well; increase injection speed; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
الخلاصة الأساسية
For PC/ABS cold slug marks, check the nozzle and cold slug well; 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 similar problems in the future
