so i have read through every page of this thread as well as the @Twitch thread. what is the current general consensus concerning the pneumatic presses (6x8 dual heated platens) or similar? i would love to hear everyone's experiences with these. has anyone tried the machines that house dual pneumatic presses with 16x20 platens?
From my research on the subject you get the best bang for your buck if you get a hydraulic/pneumatic H-frame shop press from a reputable brand(Baileigh, Dake Corp, or others)

Here is a pretty good consensus on temps and psi:


Psi is Pounds per Square Inch so if you have 16in X 20in plates the math would be:

16 X 20= 320 in sq
320 in sq X 2,400psi = 640,000psi
640,000 X 2,000psi/ton = 320 tons of pressure is the max you would need
Something like this but with your plate on it:


You would need some serious heat and thick platens to pull this off.
The biggest platens I've seen people using are 5in X 5in which would be:

5 X 5 = 25 in sq
...30 ton Press
These calcs are at the top of the requirements(2,400psi @ 180*F) and assume that your press can actually put out what it claims consistently without failing.

Personally I will be purchasing a 10 ton Dake Corp desktop model as that is within my budget.

$280 | 10-ton Dake
$550 | 3.5x2.5 Plates from RosinWorks http://rosinworks.bigcartel.com/product/rosinworks-2-5-x2-5-x-5-light-press-plates

Thats the whole kit. You could drop the price by 30% if you pieced it together but you would have to do a ton of research on quality of products. RosinWorks is definitely going for a quality reputable product and not a quick to market scheme.

If you need anyone to run your 16X20in plates let me know. That will be a lot of power and could run a lot of material. I imagine you could fit 3-400gs of flower at a time and return 20-30%(75g) in a matter of minutes. Lots of logistics to be worked out though.

@chewberto that word is above my pay grade lol what exactly is the alchemy behind creating straight Anthocyanins?

@TerpCylia I appreciate the info you posted up. That is very informative. So the press with plates that sized that I was looking at will not get the job done. It would be nice to have that kind of size but I don't think the gigantic green monster you through up is in our budget. We can spend 1500-2000 bucks. So this is what you're looking at here?

Yup that's the one I'm leaning towards. With your budget I would say you could go with the 20t and some 5x3.5in plates. I did forget to mention that the numbers are for pressing flowers. Hash and kief will require less pressure but flowers produce the best results and efficiency for production. Next most efficient would be kief and then bubble.
I saw @chuck estevez throw up a pic of something like this. Are these just too low psi to yield efficiently?

The vulcanizers are definitely too low psi to work for flower. I'm not sure of what they are able to achieve but they are also more expensive than makes sense as well. It is worth looking into their specs though and learning from their technology.

I'm currently Into dabbing straight Anthocyanins :)
View attachment 3581480
Nice! my main strain that I grow has given me straight purple squishes before when wet, but with too much water content to really get to scrape up and dab. the leaves and flowers are purple, so it makes sense a little. How do you do it? fresh/frozen/dry? temp? I've been thinking of squeezing out a nice little slab of golden rosin out of dry bud and then squeezing a wet nug next to it...hahaha, cheating I know

has anyone on here tried a unit like this? 6x8 plates. both heated. not gonna hit 1600 psi with plates that sized but seems like it could do something.

These are great in theory but I've seen a lot of people having problems with the china made quick to market presses. And alot of people have been talking shit on http://www.rosintechproducts.com . Personally I like to use products that I can rely on and fix myself. Also, modular items such as the H-Frame presses are easier to replace the plates and other parts. If you buy one of these t-shirt presses and a piece fails you will have a much harder time replacing the parts ect.

So yer say'n it's like try'n to get parts for the Batmobile. o_O

From my experience flowers have the clearest and stinkiest results. My bubble is pretty good but once I pressed a flower I didn't find myself wanting to spend the time making bubble if I don't have too. I have kiefed ounces of nugs with dry ice and gotten the same quality of rosin if not better(just make sure to separate the first, second, and third amounts). This cut the production time by 70% or so. But even then the flower rosin is the closest to the original flavor(it tastes like the plant smells when it's in peak flower).

I am wondering about THC levels per gram in juxtaposition to the BHO and Co2 while using flowers to make rosin instead of hash. People who dab will be the final judge, but chem tests cost $100.00 a piece. I will try both and hope for the best. With my first pull using hippy hash at 30+ % I'm very encouraged.

SC Labs has some results on Rosin testing. http://sclabs.com/tested.html?option=com_scl_tested&Itemid=551&view=grid&client_ids=&sclsearch=rosin
It seems that they average in the high 70%s which is really competitive with BHO. There's only a few tests so I can't draw too many conclusions without more info.
You can draw conclusions about your starting material with your yield from pressing though. The higher the yield the higher % your starting material was in the first place. I pressed some of my outdoor organic sun grown nugs from this summer and got a 16% yield(on one jar) so I could safely say it was at least 70% of the 16% yield THC in the nugs.... 16x70%= 11.2%+ THC in starting material. Very rough calcs. But being that each approximation is on the low end I would say that my final number is far below the actual %.
