Glass fiber PA requires special process parameters to avoid floating fiber and property fluctuation

문제 현상

원인 분석

Injection speed on the low side, excessive glass fiber orientation, severe floating fiber Injection speed on the high side, glass fiber breakage, reduced reinforcement effect Barrel temperature on the low side, insufficient melt flowability, floating fiber Mold temperature on the low side, poor fusion of glass fiber with matrix, rough surface Screw design unsuitable for glass fiber PA, fast wear, much breakage

해결 방법

Medium injection speed, avoid too fast or too slow Set barrel temperature to the high side of 170-230°C to improve flow Set mold temperature to the high side of 40-80°C to improve surface Select screw design suitable for glass fiber PA At 30% glass fiber content, shrinkage drops to 0.3-0.5%
