PP Injection Part Metering Fluctuation
문제 현상
Plasticizing time varies long and short; back pressure is unstable.
원인 분석
Poor feeding (bridging), high pulverized material ratio, or high hopper temperature cause screw conveying efficiency fluctuation.
해결 방법
①Cool the hopper throat; ②control pulverized material ratio and particle size; ③check the feed opening; ④stabilize drying temperature.
핵심 요약
For unstable plasticization, check feeding first.
