PBT GF15 and GF10 selection
Fenómeno del problema
The balance between strength and toughness is difficult to choose.
Análisis de la causa
GF15 has higher strength and rigidity but is more brittle, has greater shrinkage and warpage risk, and heavier equipment wear; GF10 has balanced performance.; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solución
①Select GF15 for high-stress structural parts; ②select GF10 for general purposes; ③evaluate wear and warpage risks; ④verify according to application.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusión clave
Glass fiber content selection is a balance between performance and processability; use drives grade selection.; 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
