Unstable feeding in EVA extrusion
ظاهرة المشكلة
EVA extrusion feeding amount fluctuates ±15%, causing unstable extrusion pressure and product dimensions
تحليل الأسباب
EVA pellets irregular in shape causing unstable filling rate of feeding screw; bridging or voids in hopper; feeding screw design unsuitable
الحل
1) Use loss-in-weight feeder to precisely control feeding amount; 2) Install vibrator on hopper to prevent bridging; 3) Pelletize EVA to uniform 2-3mm particle size; 4) Change feeding screw to dedicated design
الخلاصة الأساسية
Unstable feeding is caused by pellet characteristics; loss-in-weight feeding and anti-bridging are the core
