PCABS Surface Orange Peel
Problem Phenomenon
[Problem Phenomenon] PC/ABS high-gloss parts have orange peel texture
Cause Analysis
Unstable front plus insufficient mold temperature; cavity surface transfer; 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
Solution
Raise mold temperature and injection speed to stabilize the front; high cavity polishing; consistent material melt index; 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
Key Takeaway
PC/ABS orange peel requires stable front plus high polishing; 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
