EVA product elliptical deformation
Sorun Belirtisi
EVA round product ovality >1.03 after demolding
Neden Analizi
Asymmetric demolding force with the product deformed by lateral force; uneven cooling with different shrinkage in all directions
Çözüm
1) Uniform ejection design with 8-point ejection to avoid lateral force; 2) Annular uniform cooling; 3) Extend cooling time for full shaping
Temel Çıkarım
Elliptical deformation is caused by asymmetric demolding force; uniform ejection is key
