PA66 oil temperature machine configuration
Problem Phenomenon
Using a water temperature machine to control PA66 mold temperature cannot stabilize above 100℃, product performance fluctuates
Cause Analysis
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
Solution
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
Key Takeaway
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
