EMA surface snakeskin texture
Sorun Belirtisi
Snakeskin-like irregular texture on EMA extruded product surface
Neden Analizi
Extrusion temperature too low with uneven melt elastic recovery; uneven die temperature distribution
Çözüm
1) Increase extrusion temperature to the processing temperature range; 2) Homogenize die temperature within ±2°C; 3) Reduce extrusion rate to reduce elastic recovery
Temel Çıkarım
Snakeskin texture is caused by low temperature extrusion and elastic recovery; raising temperature and reducing speed are key
