After infusing in a multi-part mould, very thin layers of cured resin remain at the interfaces between the mouldings.
This resin is very difficult to remove, and if there is just a little bit of it left, the parting surfaces will not work properly together.
The gap between the mouldings is then getting bigger with every infusion.
It takes me almost a full day to cleanse the interfaces.
So far I have treated the parting surfaces between the mouldings with AFH-1 (wax mixture in solvents).
With which release agent do I best separate the flange surfaces between the moulded parts?
And can a mould cleaner help?

Frank

Put on a layer of packing tape, firmly press it on and then rip it oof with the resin stuck to it.

But that would change the size of the mould a little bit.
Has anyone experience with PVA between the flanges of a split mould?
Can I paint the split-flanges of a mould with PVA on both sides and then fit it together while the PVA is still wet?
Frank

Sorry apparently i phrased that kinda unclear. Whenever you have resin residue on the flange that is stubborn and won't come off, you put on a layer of packing tape on top of the resin and when you rip it off the resin will come off with the packing tape.

I usually scrape a little bit with a plastic scrapper, then use some compressed air and the rest is a job for packing tape. works a treat!

Ok, got it. I will try that next time.
But I need to scratch very hard with a metal blade to get the resin off.
A plastic scrapper does not help in my case.
I think something went wrong with the release agent I used. (AFH-1)
Again: any  experience with PVA?

Try the Chemical release agent from easy composites, shouldn't have any problems then
