POE extrusion feeding unstable
Fenómeno del problema
POE extrusion feeding amount fluctuates ±15%, causing unstable extrusion pressure and product dimensions
Análisis de la causa
POE pellets irregular in shape cause unstable filling rate of the feeding screw; bridging or voids in the hopper; feeding screw design unsuitable
Solución
1) Use loss-in-weight feeder to precisely control feeding amount; 2) Install vibrator on the hopper to prevent bridging; 3) Granulate POE to uniform particle size 2-3mm; 4) Change feeding screw to a special design
Conclusión clave
Feeding instability is caused by pellet characteristics; loss-in-weight feeding and anti-bridging are the core
