PBT Anti-Warpage Material Solution
Sorun Belirtisi
After process adjustment, glass fiber PBT warpage still exceeds the standard, and flatness cannot meet assembly requirements
Neden Analizi
Warpage that cannot be cured by process must be solved on the material side: adding mineral fillers uses shape symmetry to reduce anisotropy; adding amorphous materials such as AS reduces crystallization non-uniform shrinkage
Çözüm
①Add mineral fillers to symmetrize orientation; ②Add amorphous materials such as AS/ASA together with a compatibilizer; ③Select mature anti-warpage grades such as the low-warpage LD series; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
Anti-warpage formulation is a mature technical route for glass fiber PBT; mineral symmetrization and amorphous crystallization reduction work together; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
