Glass Fibre product interior shows unmelted transparent or translucent particles
Análise das causas
Screw plasticizing capacity insufficient, temperature too low; feed amount too large, exceeding plasticizing capacity; Glass Fibre melting temperature too high
Solução
1) Raise processing temperature to ensure full melting; 2) reduce feed amount to match plasticizing capacity; 3) increase screw mixing section
Conclusão principal
Unmelted particles are caused by insufficient plasticizing; raising temperature and reducing feeding are key
