How to know vent size is too huge

[JD_Moldflow]

Hi all,

We can predict is the vent is too small from air trap and positive vent region pressure result. How can one know if the vent size is too large (maybe can cause flashiing)?  Will vent region pressure result give negative value?

Thanks.

I think MoldFlow gives you the air trap locations.

From this result, you can locate vents to take the gas out.

I don;t think MoldFlow tells you the size of the vent you need to use. But if you look for the material datasheet you're using (not from MoldFlow database) you probably will find out the vent depth ranges recommended for that material.

hope it helps,
