CEF surface snakeskin texture
Fenómeno do problema
The surface of the CEF extruded product has snakeskin-like irregular texture
Análise das causas
The extrusion temperature is low and the melt elastic recovery is uneven; the die temperature distribution is uneven
Solução
1) Increase the extrusion temperature to the processing temperature range; 2) Homogenize the die temperature ±2°C; 3) Reduce the extrusion rate to reduce elastic recovery
Conclusão principal
Snakeskin texture is caused by low-temperature extrusion and elastic recovery; increasing temperature and reducing speed are the key
