moldflow1

Original design:
Hot runner with 6 valve gates, from the fill process, we can see hesitation on the top center. And there are weld lines on the main surface.

moldflow2

Solution:
No.1 opened first, when the melt front reached the No.2&3 gates, No.2&3 opened, then the No.4&5 opened, in this mode ,the top side may filled before the under side.

moldflow3

Although the runner is unbalanced, but we can control the time of the valve gates to decrease the influence of the unbalanced flow. And the 4 gates on the top side can give a good compensation for shrinkage.

moldflow4

Most of the weld lines happened on the grid, there are no weld lines on the main appearance.
