Kalinta Epoxy Mold with Divider Adjustable-11.4x7.5x2in No-Seal Large Resin Mold Integrated Clamping System - Perfect for Beginners & Experienced Artists Alike-Ideal for Creative Resin Art Projects

I wanted a good mold to make several cutting boards and serving trays. I read several low ratings complaining about difficulty releasing their project which caused me some concern.I made sure the mold was clean and that I used a release agent before pouring resin. I have experienced no problems whatsoever getting my projects to release. Typically three or four taps with the included rubber mallet and the project releases.The mold is rigid and there has been no warping with any of my pours. I was so pleased with my experience; I bought another larger mold to use. They are priced a little high, but I have used my first one five times and it still looks new. This may very well be a case of you get what you pay for. I think you can buy this product with confidence.

I’ve made about a dozen tables, cutting boards, and serving trays with just this one mold. It’s perfect. KeepIt clean. Pour correctly. Use mold release spray. It won’t fail you

I don't know why I didn't buy this years ago. By the time you spend all that money making one out of MDF you should have just bought one of these. I love the easy setup and clean up of this and I look forward to many more uses. My only regret is that I didn't buy it sooner

So the form is pretty solid, I used release spray and it came out fairly easy, the only problem I had was that I elevated it on 2 2x4 runners so I could clamp the wood into the mold and I didn’t realize until an hour later that the weight of the resin caused it to bulge at the bottom. I didn’t think I would have this issue. Now I know to use a sheet of plywood under it and it should be find. I was able to reinforce it underneath to level everything back out but that is my only complaint. Otherwise it is a great mold and I will buy more.

Great. Sturdy.

So far I have made three river-cutting boards from this mold. The first time I used Tuck Tape to line it. That was a mistake, it took me a long time to get all the tape off. Second and Third I used mole release and they fell out easily. It comes with a rubber mallet but do not count on that, the first time I used it the head flew off. I still gave it 5 stars because I had better mallets and did not purchase this for the mallet.

Well there are several issues. 1 it has way too much draft. The angle of the sides is so extreme that the resin flows past the material unless you cut the material @ 5 deg. But you can't do that very well if you have a wide piece and a live edge. What this essentially means is you do have to seal this, you just seal the work piece to the mold which means more work after demoed. I guess you can just let it go and cut the whole thing down but again thats more work. Problem 2. This is molded thermoplastic meaning it is not HDPE or pfte so the epoxy does stick to it without a heavy coat of mold release, additionally since it is thermoplastic the heat generated by the resin actually effects the shape. So if you shim it to achieve level one side ends up with a 1/16" to 1/8" bowl shape to it.... so again more work for you. I assumed they did this to make a mold this size more cost effective but it really doesn't effect the price enough to justify the bad ideas behind it. yes you can overcome its shortcomings but the savings of 30 to 40 over a custom built HDPE mold is quickly overcome by the large amount of resin waste associated with the design. For 1 project I guess it's probably a wash but 2 or more forget about it.

Easy to use only adjusts one direction - not both. Works great for making window panes.
