PEI Glass Fiber Reinforced Surface Roughness

Fenómeno do problema
PEI glass fiber filled products have rough surfaces and low weld line strength; both appearance and performance are unsatisfactory.
Análise das causas
The rough surface of PEI glass fiber filled grades is a material characteristic; fiber orientation makes weld line strength lower; fiber content affects surface finish; high fiber content increases processing difficulty correspondingly.
Solução
①For appearance parts, control fiber content or select low-fiber grades; ②increase mold temperature to improve the surface; ③optimize the design of weld line positions; ④strength verification covers weld lines.; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Conclusão principal
The surface and weld line problems of PEI glass fiber parts are inherent to the material; fiber content is a design variable; verification should target weak areas.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
