DSTDP screw slipping
문제 현상
During DSTDP extrusion, the screw slips, feed does not advance, output drops sharply
원인 분석
DSTDP granules melt too early in the feeding section forming a lubricating film causing screw slipping; feeding section temperature too high
해결 방법
1) Lower feeding section temperature 10-15°C to delay melting; 2) deepen feeding section flight to increase material gripping force; 3) dry granule surface to reduce lubrication
핵심 요약
Screw slipping is caused by premature melting; cooling the feeding section is key
