I'm trying to infuse a new part, however I have doubts on the best location for my resin entry line.

At the moment I placed the vacuum line around the entire flange of the mold and the resin inlet in the center with spiraduto assisting in the distribution throughout the piece because it is of average size with 1.30 m in length.

Is this location in the vacuum and resin lines good, or is it interesting to change the location?

Before I left the resin inlet on one side of the length and the vacuum on the other side on the flange for the resin to travel the shortest distance, however had dry areas because the resin did not distribute perfectly.

Ps: I use resin w/ gel time of 30 minutes. 

This piece is a rear spoiler, see that the vacuum lines are skirting the flange and the resin inlet line is centered with spiraduto across the entire center length.


The resin inlet hose has not yet been loaded at the time of the photo.

going from the centre out or side to side are both valid techniques.  I would personally have gone side to side as there is not a lot of room there. I can't see any obvious flow media on the surface other than around your vacuum port?  Without flow media of some sort, the resin flow will be very very slow and even on a narrow part like that, I would still expect dry patches.

Thank you Warren,

Do not infuse resin yet, I'll open the vacuum bag to put flow media in the whole piece and put it to infuse side to side. I've done this technique side by side and had dry regions, but I believe it was an error in the amount of flow media or resin.
