ABS tiger stripe
Problem Phenomenon
[Problem Phenomenon] ABS surface alternating light and dark tiger stripes
Cause Analysis
Front advancement unstable; melt temperature and mold temperature low or speed fluctuation; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry materials and should be confirmed first during troubleshooting
Solution
Stabilize melt temperature and mold temperature; smooth speed curve; stable plasticization; after adjustment, continuously sample to verify the effect, resume mass production only after confirming stability; change only one variable each time and record parameter changes to facilitate locating effective measures
Key Takeaway
For ABS tiger stripes stabilize temperature and speed; 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 later
