Hi
I’m having issues with an imprint being left on my moulds and a little on the surface of my parts after I’ve infused the carbon.
Moulds were made using uni mould system, 5 layers of wax used for release, 1st layer of carbon is the pro finish. I have used a light spray of fusion fix, sprayed into the cloth before placing in the mould. Moulds have not been post cured
Just wondering if anyone had any ideas, my moulds now look like carbon print and to remove I’m having to 2000grit sams then polish, and my part has a slight dull finish on it but not all over but just sort of fibre in one direction, sorry not the easiest thing to describe and I tried to upload a pic but it’s not letting me upload
Any ideas
Cheers

I'm maybe having a same problem. I haven't post cured the mould. I made the parts, used some spray adhesive in the mould and in the carbon to have it layed up better (no gelcoat). Now when I removed the part from the mould, there are something stuck in it. I don't know if it is the spray adhesive, or epoxy? I used Marbocoat mould sealer and release agent.

I post cured the part in the mould with infrared heater, about 3 hours in 60 degrees C. The other mould was ok, it didn't have the imprint marks. I applied gelcoat in to that mould first and cured in the same way. I didn't use spray adhesive with that.

Some a areas of the mould are clean and smooth. Same thing is in the part. I can clean the mould and the surface is then ok.What could be the problem?
