Hi everyone,

During the making of my project I had to deal with thousands of problems wich I could solve instead of one.

LEt me attach the picture and ask you what do you think is the problem. Looks like air but it shouldn´t be, I only infuse with a perfect vacuum -1bar

I use infusion with a layer of gelcoat first of all.



Thank you very much in advance for any answer, you will save my life.

Best regards

I am no expert at all but I have been reading around some to learn for my own projects..   When the part is fully infused you clamp the vacuum port first. Then you let the epoxy flow some more before you close the epoxy feed valve. 10-30 sec or so
Also you might benefit from a epoxy "flow brake" around the vacuum port..  A glitch in the flow mesh. Size of it depends..

Exactly how to do these things depends of the size of the part and a bunch of other stuff so i cant help you much moore.
