6x2 is 12 square inches. 4700÷12 = 391.66 psi.
I don't have any hard evidence for this but I feel like square would better, round prefferably. I started out with 9x2 and 1x4.5 but then went to squares and rectangles like 2x2 and 4x5. Can you get smaller plates to do smaller filter bundles and play with the different pressures? Would be cool if lots of people did this with different press designs and we could compare the results.
Cold rolled mild steel 1 inch thick is the best for the money. Cold rolled has cleaner surface and corners and is stronger, made for machinery. 1 inch thick flat bar is easily acquired in whatever width and length you'd like from a local metals supplier.
GanjaPharma mentioned the induction plate. I got one, it works well but is for sure unreliable as far as accurate temps.are.concerned. Idk if it'd be better to just get a regular hot plate. I used to heat plates on a stove top with a pool of water sitting on top of the plates. As soon as the water boils off you are around 220 for a smaller pool and maybe up to 230 with a larger pool. This worked fast and great and was easy and took no electricity. The induction plate is nice cause you don't have to hover over it waiting to do your press. You just let the plates sit on the surface until you are ready. You can also test/calibrate different power levels with the water pool/puddles.

plates aren't where its at for production I don't think. something you mentioned in another post is a better tactic I think sunfire. some type of cylindrical heated tubular press, that doesn't allow the medium to spread as it is compressed...
Yeah I've thought about a piston design for a while. I've got it all figured out except filtration, round is hard to do in these regards. Keeping the cylinders clean would be difficult too. Easily accessing the cylinder to retrieve the material will also be a task needing to be tackled. Ok so I don't have it all figured out lol! But those are minor details. What I ahve in mind is probably not what most would think up. Trying to keep it simple and work with the fountain flow instead of trying to control it. This would be a much better design in the long run I feel. I have ideas for filtration that might work. The hardest part would keeping the cylinder clean and making it easily accessible for swap out and cleaning. A well placed perfectly cut coffee filter would hell to keep the bottom well of the cylinder clean and help easily remove the spent material. The sides would need a quick whip but at warm temps the material wipes right off. I'm imagining maybe the cylinder sleave threads onto the heated base of the cylinder, give it a minute or two to warm up as well. The piston would also need to be heated. This design could potentially be automated. Have a six cylinder rosin engine banging out in your garage.
Seriously thougj, about your portable setup. It would be like a pelinail but could have a small battery and little 100 watt inverter for the enail. A solar panel on the outside of the casing. Cutouts inside for the press and a dab rig. Battery technology is crazy these days, it could be easily done, especially if you don't run the press and the nail at the same time. Idk what the irons draw but an enail is only 100 watts.

this is a little bit different types of presses, both of them. while i like what Todd and crew had going on with the reverse plate press, it does leave many safety concerns open.
my thoughts with the silicone actually need the pliability for directional movement of the oil. im working with a few people from indusrty areas i would have never thought to look, they approached me on bho blasting and i brought this up they went nuts with ideas, so next week i will be trying out the first press idea. with a few different mediums ie drysift, cured nug, and live nug.

After asking ape why I was blocked from their IG account for asking to buy just the plates for the air-mite I was given some BS story about my press blowing up if I used their plates on my press.
"We have designed this press from the ground up in a partnership with the manufacturer of the pneumatics portion. The internals of our piston along with the output shaft are changed from the standard piston to accept our plates and also to withstand heat. Unfortunately we cannot sell you our heating elements to install on the press you own because it was not designed for our plates specifically. The seals can blow and the unit is under pressure so it can be dangerous. I apologize for blocking you but we are weary of misinforming people for their own safety. "
Sunfire you can pm me if you like, Im an active member of EGA and MCPC. As far as I know that 86k plant bust was in So-Hum (Island Mountain) not Mendo although there was a big one last week up this way.

yeah its actually removable so that its just the rod! lots of options i believe for playing around with pressures. We are hoping that on Monday when the seller sends by 2 of their floor mechanics that we can have them show us a few things~
Going to try and hit up a metals supplier for some different sized paltes but roughly will keep it to the size of the Rosin Tech ones to start.
Todd and crew???
Yeah it was island mountain. And Hezekiah was one of the property owners and had 1000 plants. He's a huge hypocrite and has been chased out of many counties prior to this. He also backs a bill that's all about stopping the "environmental damages" of growing herb. They want to bring in fish and game, forestry, fire, and other departments to further police us. I saw the news coverage and pics of his huge hoops and the papers say it was a huge environmental disaster. They were operating illegally in 2014 and until late April this year. The only reason they payed the taxes to the secretary of state and re-upped their license was because I was blasting him on Facebook and shutting down all the lies he was trying to sell. I'm so glad we were never involved with him. The BOS would love to accuse us of being in bed with "cartel style" growers. Not trying to rag on your leader, bit this is all the truth, ive done a lot of research on the issue and i disagree with hezekiah. We can fight the county, and we can win! Huge multi county federal appeals case will launch this winter. Maybe you can help bring in some northern counties?
Yeah the seals thing sound like bullshit. If the ram and seals can handle the pressure without heated plates, it should handle it with heated plates. 150 - 250F isn't that much heat as far as a nylon or ptfe seal is concerned, especially at the other end of the shaft. Lots of false profits and bullshit in this industry. I really like the pics of the "gurus" shitty little gardens. I bet you and your neighbors crush way nicer gardens then most of the big names on instagram. And you gonna be stoked to not spend 4G for your press.
go for 1 inch thick colled rolled flat bar. Mild steel is fine you don't need a high carbon content for the small size of plates we use. I like the 1 inch thick cause it will hold more heat as opposed to 3/4 inch plates I was using before. I think GanjaPharma said he was using .5 inch plates. I guess it depends on your style. I do rather larger presses, at low temps it can seriously take minutes to get it all out. This is why I now realize I need self heated plates.
A spacer between the ram and the plates will greatly reduce the heat to the ram seals...
I've been thinking of these things as well. What would the best spacer material be? I'm picturing a honeycomb looking piece of aluminum? Less density would be better for insulating right? All the holes will reduce overall matter of material and surface area to transfer heat through. Size of holes and spacing would need to be experimented with to give the aluminum enough mass to still withstand the pressures. Could be easy CnC job for large production, aluminum billet is fairly cheap. Or do it at home with a drill press.
Aluminum will work depending how much pressure you are talking about. If you really think about it unless the plate is connected to the ram all the time you would have to do a long press to get the 1-1 1/2 inch diameter piston in the ram hot enough to hurt the seals. If you are using a bottle jack you could unscrew the adjuster piece in the ram to give some cooling.

As far as the spacer go I think your going to want something harder than the aluminum since it will be taking most of the pressure. I would think that aluminum would work as the pressing surface and a seal plate or spacer attached to the shaft.
Here are what Im currently using
Im thinking about cutting the bottom plate to be just slightly larger than the top plate. The 1" bottom plate holds heat for quite some time.
Sunfire if you would like to further discuss the political climate in my county I would be pleased to do so, although I dont think this is the place for it. Please PM me (I cant send one yet). As far as myself I work with a handful of groups up here that are trying to make some positive changes for small farmers in our community including EGA. I may not agree with every policy that each of these groups support but I think that they are honestly trying to make a positive difference.

so that means its settling, or what?
just wondering if there has been any more research into a threaded tube style press.
I'm thinking about it currently but would like some more input if it is already out there.
What I want to do is take a non conductive threaded tube, a threaded plunger with some form of heat proof seal, a conductive stainless steel to use as a thread on base find a way to pressurize the tube while being able to compact the material using the threading to drive the plunger
Then place the whole device on a conduction oven hot plate potentially modified to work on a smaller 2" surface.
Has any one looked into using a press plate that has a potatoe masher style head to push the oils down into the female form with holes rated to allow only the oils to seep through?
