EEA Surface Snakeskin Pattern
문제 현상
Snakeskin-like irregular texture on the surface of EEA extruded products
원인 분석
Extrusion temperature low, melt elastic recovery uneven; die temperature distribution uneven
해결 방법
1) Increase extrusion temperature to the processing temperature range; 2) Uniformize die temperature within ±2°C; 3) Reduce extrusion rate to reduce elastic recovery
핵심 요약
Snakeskin pattern is caused by low-temperature extrusion and elastic recovery; raising temperature and reducing speed are key
