HDPE mold temperature 20-60
문제 현상
The mold temperature of HDPE products was set to 80℃, and the molding cycle was greatly prolonged
원인 분석
HDPE crystallizes quickly; too high a mold temperature delays cooling with no quality gain, and the cycle is prolonged in vain; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
Control the HDPE mold temperature at 20-60℃; take the upper limit for thick-walled parts; 30-40℃ is enough for ordinary parts; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
HDPE is a low mold temperature material, and cooling efficiency takes priority; 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
