PA6 Flash
문제 현상
Thin-sheet flash at the parting line and ejector pins.
원인 분석
PA6 melt has low viscosity and easily penetrates into fitting clearances under high pressure; high injection pressure, insufficient clamping, and mold wear.
해결 방법
①Reduce injection/holding pressure;②calculate the clamping force;③repair the parting line and ejector pin clearances;④appropriately lower the material temperature to increase viscosity.
핵심 요약
Low-viscosity nylon flash = a war between pressure and clearance.
