PVDF Extruded Pipe Surface
Fenómeno do problema
Surface defects on extruded pipe.
Análise das causas
Improper die temperature or material buildup; PVDF melt characteristics make the surface sensitive to temperature.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solução
①Optimize the die temperature; ②clean the die buildup; ③stabilize extrusion; ④check the die condition.; After adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
Conclusão principal
The extrusion surface is managed by die temperature and cleanliness.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; Include this case in the defect archive as a reference for troubleshooting similar problems in the future
