HDPE pipe temperature
문제 현상
HDPE pipe extrusion surface is rough
원인 분석
The extrusion temperature is too low causing poor plasticization, or the die head temperature is uneven; 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
Extrusion temperature 190-230℃; calibrate each temperature zone of the die head; check plasticization quality; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes, to facilitate locating effective measures
핵심 요약
Pipe surface quality is guaranteed by the temperature curve; 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
