I only do a 10g puck as it is easy to manage, I have done 14g in a single 40mm puck but it was a pain to get between the plates. You can do 2x pucks at once, so pressing 20g at a time is easy, 28 can be done but the prepress would need an Irwin clamped to pre squish it enough to fit between the plates more easily.Is 10g the biggest amount in one go?
IMO the best tip to prevent blowouts is to pay attention to how little pressure it actually takes for rosin to start flowing, once you get to that point where the bag wets out you wont need a whole lot more pressure for the duration of the press.
Would you say this applies to flower pressing also?
I have the 6 ton press and usually press 3.5g pucks. I am always listening and watching during a press. I can hear the light crackling sound of the rosin coming out of the buds, and if the buds are dank enough then I can see rosin coming from the edges of the plates. Once I see this, should I not apply more pressure? I have always figured that the rosin needs to come from the depths (center) of the puck so you keep pressing until you have maxed out the press with significant arm pressure on the handle.
Not having a gauge, I have maxed out pressure at the end of each press and have experimented more with temp, heat soak, and time.
Are the bags supposed to have this much gap down the sides or do dabpress make the bags too big for the recommended prepress.?
Inserts?Since the pre-press mold has inserts to make smaller pucks, the less material you have loaded the more of a gap you will have. 11-12g should fill the bag, 7g should have a gap that will fill in as the material is pressed out.
I was gonna try flipping the 3"x3" plates upside down and adding rectangular spacers to fill in the machined areas and remount them, but wasn't sure if the undersides were anodized as well.... on second thought the undersides probably have the threaded bolt holes that would be "exposed" on the "new" pressing surface...
hoping 3"x5" plates are available so I can do two 7g bags side by each..

Thanks I was worried about over loading but even with 12g there is space to spread
Flower needs more pressure than hash cause you are extruding the melting resin through many more nooks and crannies in the plant material.
With hash you're essentially just melting it through the filter bag. With the 6 ton I usually apply pressure when it feels like it will take some, if it takes significant force when cranking the handle it's probably too soon to be adding pressure IMO but Id be curious to hear what others think. It's hard to explain in text but if you picture in your head how the puck feels when it's just wetting out, and then how it feels to press too hard, right through the paper, and just kind of mentally divide that in half, that's where you want to be.
There's a large possibility that made zero sense and Im gonna have to blame it on the blueberry haze hash rosin
Now I might crank a little harder if I'm re-pressing pucks for time capsules, but one thing I've learned is to really try to avoid using so much temperature or pressure that the rosin is a chore/burden to collect. That really kills the buzz!!
I have the 10ton press with the recommended pump with a gauge that goes way past where I think I need to be, do you know the max psi I should go for with these plates if talking a 2x3.5"puck? Struggling with the mathsLess pressure will usually lighten the color of my rosin too
Does anyone freeze material to help with yield? I read about it but when applying heat from the plates I don't see how it helps, getting OK results at 90c but it's quite a dark return, 70/80 is much better but significantly less yield

I use this prepress mold,if talking a 2x3.5"puck?
That is at the gauge of the standard dabpress pump? Sorry I am still a bit confused sometimes by these psi and tons and lbs and all. While I get the theory I am not sure or confident what my gauge really indicates.I will press between 2200psi and 3000psi
@Sick Vape
Here is ~1200 PSI at the material. IME this is really the far edge of where we want to be, any more pressure and I'm just pressing out chlorophyll and other undesireables as indicated by the darker oil being extracted once those levels of pressure are reached.
The PSI measurement on the gauge is only measuring the pressure in the hydraulic system, it has no way of knowing what tonnage cylinder we are using or how large of pucks we are pressing. That's why we have to be math wizards to figure this out lol
The cylinder effective area (each cylinder has it's own #) is what converts the pressure in the hydraulic system (i.e. pressure registering on the gauge) to actual total pressure delivered. For the 10-ton press the cylinder effective area is 2.25, for thet 12-ton press it's 2.75. Pressure on gauge x cylinder effective area = total pressure being delivered.
For this reason, it's why the same 10000 PSI hand pump works with 5, 10, 15 or 20 ton cylinders.
With more effective area inside of the cylinder, we are able to deliver more force, and this is where we need to be scientists to understand all of that
BTW this is some of my own The Church by greenhouse seeds, pressed with ~1200 PSI at the material at 200F for 2 mins. RH of the flower was 60% in the jar and the room was mid 50's. Flower was jarred a little over 6 weeks ago. 19.5% yield off misc smalls, I expect the tops will be yielding a couple % more!
