Injection Molding

EVA surface orange peel texture
Problem Phenomenon
EVA product surface has orange-peel-like uneven texture with rough hand feel
Cause Analysis
Mold temperature too low <30°C; after the product surface rapidly cools and solidifies, the interior continues to shrink, causing surface unevenness; injection speed too low
Solution
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
Key Takeaway
Orange peel texture is caused by rapid cooling and solidification; increasing mold temperature and holding pressure are key
