Snakeskin Pattern on CMC Surface
Sorun Belirtisi
Snakeskin-like irregular texture on the surface of CMC extruded products
Neden Analizi
Extrusion temperature is low and melt elastic recovery is uneven; die temperature distribution is uneven
Çözüm
1)Increase extrusion temperature to the processing temperature range; 2)Homogenize die temperature ±2°C; 3)Reduce extrusion rate to reduce elastic recovery
Temel Çıkarım
Snakeskin pattern is caused by low-temperature extrusion and elastic recovery; temperature increase and speed reduction are the key
