Nah. Flow mesh can either work, or not work. If your mesh doesn't work, then your part simply won't infuse, it won't cause issues like this. 

A friend told me that my infusion mesh is not good, but i think the only problem i have is about air losses.. next week i will try again!

Don't worry if it is flowing quickly as this will not affect the part, I only say slow it down by clamping the inlet pipe to give you a little time to work through the infusion, fast is fine.

I'm not as experienced as a lot of people on here but I would use the peel ply, put the mesh on and spiral inlet side,

on the vac side cut the mesh out and put the oulet directly on to the peel ply not on the mesh,




this will give you time as the resin will flow very slowly across the peel ply.




once the part is wet out clamp the vacuum side and then give the inlet some extra resin before clamping off.




if everything is vacuum tight then the part should work ok.

here we are ... I decided to change some working methods .. first of all, put everything in a bag mold to reduce losses , the second does not use the peelply , perforated film instead of peeply . Then I changed to resin inlet , placed in the center of the mold . Unfortunately a microleaks has ruined my work , maybe this piece is more complicated than I thought . also even slowing the resin inlet , it flows too quickly

Leave the vacuum for at least half an hour, preferably one hour. You should clamp the part off from the vacuum pump, to eliminate any possibility of the pump having leaks. Then when you come back to the part, turn the pump on and then unclasped the hose. You should hear no audible difference in the tone of the pump. If you do, then it is likely you have a leak and you need to find it before continuing.

Yeh ho intuito che era il problema. L'infusione deve essere stretto assolutamente al 100%. Si dovrebbe essere in grado di tornare alla parte una settimana dopo l'infusione e ancora trovare la stretta borsa. [/citazione]

se siete dopo una buona finitura per la cosmesi poi trattenere sul infusione e aspettare più a lungo prima di infondere, assicurarsi di avere un vuoto di 100% e poi quando si infondere dare il tempo di resina a Degas, se siete preoccupati per la vita pot poi trasferire la resina mista ad una pentola con una superficie più ampia e aspettare che la resina è bolla liberamente,

Yeh I guessed that was the problem. Infusion needs to be absolutely 100% tight. You should be able to come back to the part a week after infusing and still find the bag tight. 

if you are after a good finish for cosmetics then hold back on the infusion and wait longer before infusing, make sure you have a 100% vacuum and then when you infuse give the resin time to degas, if you are worried about pot life then transfer the mixed resin to a pot with a larger surface area and wait till the resin is bubble free,

thanks for the answer hanaldo! I work with the infusion system, i do the vacuum, and wait around 10min before to start the infusion, the resin flows fast even i do a break in the infusion mesh.. Wait 24h and when i demould, i find the pression to 0 in the pump and the bubbles on surface. Maybe i not wait enought for the resin degas, is there a metod to degas resin with the EC resin trap? Or just need a little hot air?
