EEA Vacuum Section Material Overflow
문제 현상
Material overflows at the vacuum vent section during EEA extrusion, vent hole blocked
원인 분석
EEA melt viscosity is low and overflows at the vacuum section; vacuum section temperature is high, viscosity even lower, aggravating overflow; improper vent hole design
해결 방법
1) Lower the vacuum section temperature by 5-10°C to increase viscosity; 2) Add a baffle above the vent hole to prevent overflow; 3) Increase screw speed to accelerate conveying and reduce residence
핵심 요약
Overflow is caused by low melt viscosity; lowering temperature and adding a baffle are key
