PA66 glass fiber grade mold temperature
Sorun Belirtisi
Glass fiber reinforced PA66 products rough surface with floating fibers, still cannot be covered after spraying
Neden Analizi
When glass fiber material mold temperature is low, the melt front is quenched, resin has no time to encapsulate the glass fibers, floating fibers solidify directly on the surface; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Çözüm
Raise glass fiber PA66 mold temperature to 90-120℃; injection speed medium-high; melt temperature at upper limit; local mold heating if necessary; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
Glass fiber material surface quality is mainly guaranteed by high mold temperature; 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
