Glass Fibre extrusion unstable feeding
Fenómeno do problema
Glass Fibre extrusion feed amount fluctuates ±15%, causing unstable extrusion pressure and product dimensions
Análise das causas
Glass Fibre pellet shape irregular causes unstable feed screw fill rate; bridging or voids in hopper; feed screw design unsuitable
Solução
1) Use loss-in-weight feeder to precisely control feed amount; 2) install vibrator on hopper to prevent bridging; 3) granulate Glass Fibre to 2-3mm uniform particle size; 4) change feed screw to dedicated design
Conclusão principal
Unstable feeding is caused by pellet characteristics; loss-in-weight feeding and anti-bridging are the core
