PA66 burnt gas trapping
Sorun Belirtisi
PA66 products burn at fixed positions, and recurrence occurs shortly after cleaning
Neden Analizi
Burning at fixed positions is structural gas trapping, venting channels are insufficient or blocked by oil contamination, and adiabatic compression occurs repeatedly; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience
Çözüm
Add vent inserts or vent grooves at that position; regularly clean vent grooves; reduce final-stage injection speed; after adjustment, take continuous samples to verify the effect, confirm stability before resuming mass production
Temel Çıkarım
Burning at fixed positions must structurally improve venting; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
