MOLDFLOW Gate Placement

Place gate to achieve balanced fillingGate in thicker areasGate far from thin areasPlace gates to achieve unidirectional fillingAdd gates as necessary to reduce pressurePrevent overpacking by adding gates
Very balanced fill, Unidirectional orientation, possible packing variation
Mostly balanced fill, Radial orientation, possible warpage due to orientation
Mostly balanced fill, Radial orientation,Large weld line formed at near EOF
Unbalanced fill, Weld line forms early, Radial orientation
Gate in a thicker area to help pack that thicker area betterGenerally lowers pressure to fill the part
When there is significant changes in wall thickness, avoid gating close to thin areasThe polymer will favor the path of least resistance and will a difficult time filling the thin feature, if at all
