ABS granule hopper bridging
Sorun Belirtisi
The hopper feeding is intermittent, the plasticizing amount fluctuates, and the product is good at times and bad at times.
Neden Analizi
The hopper temperature is too high or the granule shape is uneven (including crushed material), causing the granules to bridge at the hopper mouth; bridging is more likely when the regrind flake ratio is high.
Çözüm
①Pass cooling water through the hopper neck to control the temperature; ②control the crushed material ratio and particle size; ③install stirring or vibrating feeding; ④keep the drying air circulation normal.
Temel Çıkarım
If the feeding is unstable, no matter how accurate the process is, it is in vain.
