PP Glass Fiber Exposure
Sorun Belirtisi
【Problem Phenomenon】Glass fiber PP surface has floating fibers and is rough
Neden Analizi
Fibers enrich the surface; low melt temperature, mold temperature and slow injection speed cause poor coverage; during on-site troubleshooting, verify item by item according to this mechanism to 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
Çözüm
Increase melt temperature and mold temperature; increase injection speed; mold polishing; after adjustment, take continuous samples 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
Temel Çıkarım
For PP floating fibers increase temperature, speed and pressure, polishing assists; 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
