@ekricketWho is an engineer up in here that can lead me to thermoplastics melting point chart OR just tell me what thermoplastics have lower melting points...

Curious what a super diamond would do in there, if you could remold it even enough to make a difference.Okay so. Ran into a problem with the other mold because it was TOO FAT to fit into my hydraulic press...no love for big girls.
Anyways, ordered a new steel bead blasted mold:

Anyways, gonna start seriously trying to make some 10g chips that stay together next week. Will be updating this thread more frequently now that I have the mold I'm going to use.
Again, stay tuned.
Today I made this!

There are obviously a litany of problems but happy to have made something that mildly resembles a poker chip. Its birth weight was around 6g so very underweight.
Pretty sure it’s just a mold to test clays, not the final mold to press them. He’s going to get the clay right first, then build all the other 99 steps. I tried to get him to build a whole factory before even getting any clay but he’s bound and determined to do it one step at a time.looks cool, but it seems like you made the mold to exactly 39mm? i.e. you left no room for error to lathe off the rough edges and maintain 39mm.

Use lead-backed adhesive labels. Gold inserts if you can afford it.Its birth weight was around 6g so very underweight.
Yeah like maybe mill them like <1mm just to make everything flush?Amazing work @Grandmasturkey! I love reading about your progress. I wonder if it'd be possible to flatten just the recess with a wooden clamp using smaller diameter ceramic blanks (or some other smooth flat disc with the same diameter as the recess). I'd worry about the outer edge of the chip warping in that case but it might be worth a shot. If you could find washers with the right inner/outer diameters to cover just the part of the chip with the mold, maybe you can press them both at the same time to avoid outer edge warping while still flattening the middle recess.
Edit: thinking about this, I bet a more aggressive sanding of the middle (or milling) would probably be more effective
Attention attention update:
I have figured out a way to flatten the center of the chips:

This is a 1" stamping blank
I place one of these babies on each side of the chip in my hydraulic heated press, like so:

Then press it for about a minute at a reasonable temp:

Then it comes out flattened and smooth in the middle:

Then you can stamp!
