Sorun Belirtisi
Ring-shaped ripples or color differences (gate blush) appear around the gate of PET products, affecting appearance.

Melt flow at the gate is unstable (jetting effect); gate size does not match injection speed; venting in the gate area is poor.
Çözüm
Optimize gate design, enlarging it or changing the type; use multi-stage injection to control flow speed at the gate; improve venting; appropriately increase melt temperature.
Temel Çıkarım
PET gate blush can be eliminated through gate design and injection process optimization.
