PPS glass fiber reinforced floating fiber
Problem Phenomenon
Floating fiber texture on the surface.
Cause Analysis
Insufficient surface layer coverage; low temperature and slow speed.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solution
①Increase temperature; ②increase speed; ③strengthen holding pressure; ④polish the cavity.; 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
Key Takeaway
Floating fiber is improved through temperature and speed to improve coverage.; After confirming effectiveness, solidify 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
