Resin at the parting surfaces between the mould parts of a multi-part mold

Group: Forum Members Posts: 27, Visits: 123	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

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!

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? Frank Edited 6 Years Ago by Frank
