EMA surface snakeskin texture
Fenómeno del problema
Snakeskin-like irregular texture on EMA extruded product surface
Análisis de la causa
Extrusion temperature too low with uneven melt elastic recovery; uneven die temperature distribution
Solución
1) Increase extrusion temperature to the processing temperature range; 2) Homogenize die temperature within ±2°C; 3) Reduce extrusion rate to reduce elastic recovery
Conclusión clave
Snakeskin texture is caused by low temperature extrusion and elastic recovery; raising temperature and reducing speed are key
