I wandered if the foam expands with heat release. I was wondering because i thought i wax mold would be really simple to make, and demolding won't be a problem whatsoever.

That's something that could work. Foam does heat up do to catalyst reactions however it doesn't really get hot. CNC machine wax or jewelers wax could work as they are harder than parafins. Perhaps wood planks between the clamps and the wax to avoid breaking the mold.

I don't know much about CNC machine or jewelers wax, but I wouldn't suggest to use it for molds. I think wax mold will not last long...
BTW, how hard is this stuff? I think about making prototype from it...

It's wax made for models. Jewelers use it to sculpt fine detail without it breaking. It can be tooled easily and repaired with a pen torch. I've got a couple plates of the purple I'm saving for a tutorial.
Here's a link showing wax in a large sculpture for casting bronze
As molds... if the wax lasts for a few hundred blanks and are easy to cast as molds it might be worth looking into. When they are cooled they are ready to use. I'd suggest the keysets in the russian polyester/concrete mold tutorial. I don't have the link to that forum anymore ... Vy you got that link handy?

And what is the mold made of? Some kind of epoxy resin? Sorry for all the questions

It happens so, that my first posting on your site has nothing to do with lures. But I be damned! I would never have thought there already exists a software product capable of such accuracy in translation! Of course, it is far from ideal but I failed to spot any actual mistakes that could mislead a lurebuilder.

Excellent work Dennis! Welcome to Tackleunderground I'd like to see more pics of your lures and molds.

Correction: those are not mine. I tried to make my own lures with this technology, but lost interest. It sure as hell works, but I believe it is more fun to deal with wood. That's what brings me here. I am trying to catch up with you, guys, so for a while, I am just reading. But I promise, you will see my lures, sooner or later.
