PA66 oil temperature machine configuration
문제 현상
Using a water temperature machine to control PA66 mold temperature cannot stabilize above 100℃, product performance fluctuates
원인 분석
Atmospheric water temperature machines have a low upper limit and high vaporization pressure at high temperature; the 80-120℃ mold temperature PA66 requires exceeds its stable working zone; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
해결 방법
Configure oil temperature machine for mold temperature above 80℃, control accuracy ±1℃; high-temperature oil pipes and fittings selected for temperature and pressure resistance; regularly check oil quality; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
High-mold-temperature conditions must be equipped with oil temperature machines, water temperature machines are insufficient; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
