PBT Floating Fiber Material Countermeasures
ظاهرة المشكلة
After process optimization, floating fiber is still obvious, and the customer rejects appearance parts
تحليل الأسباب
Process improvement of floating fiber has an upper limit; the material side is the radical cure: specially surface-treated glass fibers enhance bonding; compatibilizers such as SOG act as a bridge to increase the bonding force between PBT and glass fiber
الحل
①Select grades with surface-treated glass fiber; ②Add compatibilizers such as SOG to improve the interface; ③For parts with strict appearance requirements evaluate mineral filling as a substitute; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability
الخلاصة الأساسية
The radical cure for floating fiber lies in interface chemistry; compatibilizers and surface-treated glass fiber are the two keys on the material side; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
