Infusing "downhill"

Happy New Year Guys!

Quick question for you all concerning the infusion of a bowl shaped object with a single vacuum port at the lowest part of the mold and resin feed coming in from the top edge (circumference).

I spent most of my day today watching YouTube videos and ran across some information regarding converging vs. diverging resin flows.

Normally you would infuse a part like that working “uphill” and against gravity, but I’m just curious what freaky thing might happen if you did it the other way around?

It seems to me (a total newbie) that so long as the resin pot is BELOW the part and the resin feed rate was monitored it would work just fine… But then again, what do I know?

:slight_smile:

Thanks for your time,

There nothing that will go massively wrong by going downhill, it’s just better to be infusing up hill. By going up the resin front will push any air in front of it with the help of the air floating on the resin. On a boat this could make a big difference but on a small part it would make sweet FA.

If possible, infuse against gravity. Racetracking is more severe when gravity helps, and air inclusions are more likely. (nothing that a real good vacuum will solve, but anyhow)

With some products you just cannot prevent working up-side-down. That’s life…

I would infuse uphill - resin feed in the bottom center and vacuum up around the perimeter
