Tablet Pressing
« on: August 13, 2009, 05:59:32 PM »
I've been taking a look at tablet presses and I had a couple questions. First it seems the basic quality models from the big companies start at around $3k but it seems you can get them from some independent smaller guys from $1,500. Is that about right? Also, mixing. If you are making 200mg tablets with 100mg active ingredients and 100mg binders what is the best way to assure an even ratio? The mixers I've seen are these V shaped cyclinders that spin. Are those really want you should be using and have to be using to get an even mix and would an even mix even occur with something like MDA/MDMA and a typical binder? Also the tablet presses measure in depth of tablet and not weight so if you want 200mg do you just keep modifying the tablet depth and weighing it until you get the perfect 200mg? Thanks in advance...... for help with my future custom protein tablets and nothing more :-)

When I made caffeine pills, I used a ball mill to ensure an even consistency and mixture.  You are right on the tablet presses.  I have never purchased one, nor have I looked extensively into one, simply because I don't tablet a whole lot of anything haha.  I don't know if you live in the US or europe, but most are wired for 220V so watch for that.  Also, if you do happen to find a reliable seller that doesn't end in a court case, let us know hahaha.

As for tablet press depth, you can weigh out a 200mg sample of your material, then place it in and set the depth to that.  One thing that is a pain about tablet presses, is you will either have to maintain a steady mixing style (ball mill for exactly 60 minutes each time, using the same chemicals and the same preparation style), otherwise you'll have to reset the fill depth each run.

Wouldn't tossing the powders in a ball mill,with out any balls.. so basically a rotating cylinder, maybe with something to agitate, work really well to mix all of the powders uniformly?

I wouldn't buy a tableting machine, I understand that they watch those things pretty intently.

Yes they are one of the few watched machines matter of fact. I would not advise anyone to buy one because there is a great chance it will be a controled delivery considering there is not many uses for an amature for a pill press.

Hmmm. Guess I'll get a reloadable VISA with a fake id at Walmart then and get an anonymous drop at the UPS Store with a fake id then before ordering. But they sell them on Ebay and although I haven't taken a look at the past sales (just check "completed auctions") I think plenty of individuals are buying them.

I have heard rumors they can be made out of the machines that refill bullets, but I have never heard of any success, etc.

There's a guy on Ebay selling quality ones for $1300 and I think he's shipping from Lithuania. That should be safe. I've bought a bunch of GPS jamming equipment on Ebay from a guy shipping from Bulgaria before. From the US I probably wouldn't have bought but the FBI isn't doing any controlled deliveries when it's originating from Eastern Europe unless it gets stopped at customs and they know what it is and really care (and by that time you'll know it's going to be controlled). And customs are stupid when it comes to non-standard stuff. I've had them open ATM skimmers before and they let them go.

Im interested to know if anyone has had any wins with the herbal pill press things for about $100?
I just want somthing that isnt capsules they always turn into a soggy gelatinous mess over a night out....
Was just thinking if you had one of thoes herbal pill makers, if the tablets would turn out solid or horribal and crumbly?

Also what is the choise binder? I have no experience whatsoever but Ive herd caffine is good because it gives a realy nice surface....

I know it sounds a bit strange but what about elmers glue to hold pills together? Its non toxic and creates a pretty strong bond that one or two drops should be enough to turn power to a puddy like consistancy.

A woodshop vice with a ~$30-50 pill bit(think that's the word) does the trick. I know a chemist that uses it all the time for MDMA.

I can't remember the output but I think it's 1 pill every 15 seconds all done by hand of course.

[----00----]

...it's kinda shaped like that. You put the bit with the binder(he uses china clay) and the molly in the thing in the center and then twist the vice tightly, untighten, and done.

They look really professional when done like some classy rolls.

I've heard microcrystalline cellulose is supposed to be pretty good. There is a synth on here about how to make it, pretty simple but I don't know how well it works or how easy it is to deal with.

I'd seriously consider doing what they do to make suckers, or even just making suckers ::)
Getting a boiling hot, overly saturated solution of  sugar and poring it into a mold sprayed with an oil so it doesn't stick later on could probably produce some nice little tabs.  The substance could be added at the last minute to avoid any decomposition, obviously you'd need rapid stirring with a blender, etc to mix it well. Sugar obviously has its problems, but suckers seem to stay fine in plastic or wax paper.  I dunno, maybe that is a stupid idea.. and possibly another stupid idea..


I have always thought a person could more easily produce "sticks" of the pressed supplement and have notches to encourage it breaking in the correct place, giving the correct dose.

The stick could be made by having a groove cut into a piece of metal or other suitable material, and then having a ton of bolts to tighten down on another piece of metal that fits into the groove, or just press it down with a ram. The ram sounds like the better option, but I think you could put a lot of pressure on the supplement with some bolts, if you consider the surface area of the stick isn't going to be more then an inch or so at most, and the bolts are large and you can get leverage to turn them.

You know, if you want to go really ghetto and are just making a few hundred instead of a few thousand chocolate might work too. I remember as a little kid making chocolate stuff with melted chocolate. You could make a sheet with indentations, drop a little melted chocolate, drop the 100mg of powder on top, then top it off with more melted chocolate. Let it dry and you have chocolate pelts of X.

Edit.... Or if you can figure out how to mix X consistently into melted chocolate then you could mix a big 5 gallon drum up, mix it, and then just spread the chocolate on sheets with thousands of indentations on it. That could go quick if you can figure out on how much X is needed in how much chocolate in how big of an indentation to get exactly 100mg per chocolate bead.

@poison - I was down around 10-11 seconds a tablet with my home-made die and hydraulic press (also homemade).  The vice also works and could be made more expedient by welding in a ridge to hold the die in the jaws while tightening (so you don't have to hold it with your hand).  I will say that this method works reliably for even a couple thousand. 

What I might suggest, would be finding an e-bay seller that is local, and going to his place of residence.  Try to find a seller within 1 state from yours, obviously.  I would also look for a buy it now type auction.  Talk to him in person, and offer him cash.  If he takes it, walk away with no looking back.

Binders: Microcrystalline cellulose is the best possible, followed by lactose.  You'll also want stearic acid and magnesium stearate, for dry lubrication.  One prevents the tablet from sticking to the walls of the die, and one prevents the tablet from sticking to the actual faces of the die, I don't remember which is which though. 

I'm working on my tableting tutorial for my website, I'll prob post it up to my FTP once it is done.

I guess it might be appropriate to post this here but not too sure. Kinda goes along the lines, but what is everyone's opinion on just using gel capsules? I figure this really would be the easiest but how would they sell? Would anyone really buy them?

I've heard too many issues with the gel caps not fully dissolving, and the tablet actually not even working.  Some people prick holes in them to help with this issue however.
