Group: Forum Members Posts: 10, Visits: 26	hi guys, Im trying to make a mold of a metal watch case and bezel. What would be the best method to use for this? Im going to be using the mold to cast a carbon fiber case. Will the gel coat and molding putty work or is the watch case too small for this material. Any guidance is highly appreciated. I ve checked through the forum and cant really find anything on this particular question thanks! Tags cast casting epoxy gel coating molds

Press it into alle the edges of the mould, add some pressure (possitive mould pressing into the negative mould for example) let it cure and demould... You might have some airbubbles and so on in your first test, but you will have to do some trial and error like I said. Hope I made myself a bit understandable? thats great man, thanks for the direction. my only concern is that my mold is a silicone, 2 part, with parting line. should i fill each mold separately and stick them together or should i make a mold using epoxy putty instead?

With a silicone mould it would just be "pushed into the silicone, probably causing some deformation on your CF part and maybe dont have enough pressure causing some pinholes and so on Matthieu Libeert Founder MAT2 Composites X Sports website: www.mat2composites.com
