PA66 water line design calculation
Sorun Belirtisi
PA66 mold uneven cooling causes warpage, repeated machine adjustment cannot cure it
Neden Analizi
Water line diameter too small or series connection too long, cooling water heats up greatly, cavity points cool inconsistently, process adjustment cannot compensate design defects; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Çözüm
Water line diameter calculated by flow to ensure turbulence; cavity circuits equal-length parallel; temperature difference controlled within 5℃; add auxiliary water lines if necessary; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
Uneven cooling is a design problem, only water line calculation and modification can cure it; 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
