EMA surface orange peel
ظاهرة المشكلة
Orange-peel-like uneven texture on EMA product surface with rough hand feel
تحليل الأسباب
Mold temperature too low <30°C; product surface cools and solidifies quickly, then interior continues to shrink causing surface unevenness; injection speed too low
الحل
1) Increase mold temperature to 40-50°C to delay surface solidification; 2) Appropriately increase injection speed; 3) Increase holding pressure to reduce internal shrinkage
الخلاصة الأساسية
Orange peel is caused by rapid cooling and solidification; increasing mold temperature and holding pressure are key
