PEEK Fiber Floating and Appearance
Sorun Belirtisi
【Problem Phenomenon】The surface of glass fiber/carbon fiber PEEK products has exposed fibers and is rough, with both wear resistance and appearance poor
Neden Analizi
The fibers have poor wetting with the matrix and float on the surface with the melt flow; when melt temperature and mold temperature are low and injection speed is too slow, fibers more easily enrich the surface forming floating fibers; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Çözüm
Increase melt temperature and mold temperature to improve wetting and encapsulation; increase injection speed so that fibers embed with the melt; polish the mold surface and optimize venting to reduce fiber retention; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Temel Çıkarım
Floating fibers rely on temperature and injection speed to promote encapsulation; mold condition also affects fiber distribution; 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
