Jetting marks/snake patterns on products
Sorun Belirtisi
Twisted snake-like patterns appear on the product surface, extending from the gate
Neden Analizi
Gate size is too small, causing a melt jetting effect; the melt jets when entering the cavity instead of advancing smoothly; injection speed is set improperly
Çözüm
Enlarge gate size to eliminate jetting; change to a fan gate or side gate; adjust injection speed to achieve advancing filling (slow first, then fast)
Temel Çıkarım
Jetting marks are a sign of improper filling flow pattern
