PA6 Glass Fiber Grade Mold Temperature
Fenómeno del problema
Glass-fiber reinforced PA6 products have severe surface floating fibers and poor gloss
Análisis de la causa
When the mold temperature of glass-fiber reinforced PA6 is low, the melt front cools rapidly, and the glass fibers solidify on the surface before being coated by the resin, forming floating fibers and a rough surface; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solución
Raise the mold temperature of glass-fiber reinforced PA6 to 80-100°C, combined with a higher injection speed so that the resin fully coats the glass fibers; after the mold temperature is increased, floating fibers and surface gloss are significantly improved
Conclusión clave
High mold temperature is the most effective means of improving the surface quality of glass-fiber reinforced PA6; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
