POE internal shrinkage voids
Sorun Belirtisi
POE thick-wall product center shrinkage voids, diameter 0.5-2mm
Neden Analizi
Thick-wall area interior shrinks after cooling but the surface has solidified, cannot be refilled; holding time insufficient, gate freezes too early
Çözüm
1) Extend holding time until the gate fully freezes; 2) Increase gate size to delay freezing; 3) Product design to reduce wall thickness difference
Temel Çıkarım
Shrinkage voids are caused by thick-wall shrinkage and insufficient holding; extending holding is key
