EVA surface snakeskin pattern
Problembeschreibung
Snakeskin-like irregular texture on EVA extruded product surface
Ursachenanalyse
Extrusion temperature too low with uneven melt elastic recovery; uneven die temperature distribution
Lösung
1) Increase extrusion temperature to the processing temperature range; 2) Make die temperature uniform ±2°C; 3) Reduce extrusion rate to reduce elastic recovery
Wichtigste Erkenntnis
Snakeskin pattern is caused by low-temperature extrusion and elastic recovery; increasing temperature and reducing speed are key
