PA6 Flash
Sorun Belirtisi
Thin-sheet flash at the parting line and ejector pins.
Neden Analizi
PA6 melt has low viscosity and easily penetrates into fitting clearances under high pressure; high injection pressure, insufficient clamping, and mold wear.
Çözüm
①Reduce injection/holding pressure;②calculate the clamping force;③repair the parting line and ejector pin clearances;④appropriately lower the material temperature to increase viscosity.
Temel Çıkarım
Low-viscosity nylon flash = a war between pressure and clearance.
