PA6 Floating Fiber Improvement
Fenómeno do problema
Glass fibers are exposed on the surface of glass fiber reinforced PA6 products, with a prickly feel to the touch
Análise das causas
The melt front temperature drops quickly and the resin solidifies before it can coat the glass fibers; low mold temperature and slow injection speed are the main process inducements of floating fiber; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based only on experience
Solução
Raise mold temperature to 80-100°C, and speed up injection so glass fibers are coated by resin; take the upper limit of melt temperature; when surface requirements are high, select a special grade with good coating ability
Conclusão principal
Floating fiber treatment relies on high temperature and high speed to ensure resin coating, and grade selection is also very important; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
