HDPE screw selection
문제 현상
HDPE plasticization is poor and energy consumption is high
원인 분석
The screw compression ratio does not match the melting characteristics of HDPE; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
해결 방법
Select a screw with a compression ratio of 2.5-3.0 for HDPE; length-to-diameter ratio above 25; replace worn screws; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
HDPE screws should be selected to match the melting characteristics; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar future problems
