TV Mould


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.

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.

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.

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

The picture is showing V/P transfer. The pressure will be transfer into 59.08Mpa when the product is filling 99%.
