How much pressure do you need to press rosin?
Ahhh... The age old question! How much pressure do I need for my Rosin Press? The important number that we need to pay attention to is Platen PSI, and we will break down exactly how to figure that out in this article, and how many Platen PSI you need for a full extraction. This guide will help you build or decide which press fits your needs.
When extracting rosin, whether it be from fresh flower or from dry sift, there are two main factors - heat and pressure.
They are inversely affected by one another. The more heat you use, the less pressure you need. Conversely, the more pressure you use, the less heat you need.
What is the best temp to press rosin?
You may think that more heat will result in larger yields. This is not true! Using too much heat will burn off terpenes and other compounds that make rosin so sought after. You should stick to lower heat.
- For flower: 220°F - 240°F for about 30 - 45 seconds
- For dry sift/kief/hash: 180°F - 210°F for 45 - 90 seconds
As soon as you finish your press, remove rosin from the plates as fast as possible. This will minimize any degradation of compounds like CBD and terpenes. Pure Pressure makes some really cool Gold Plates which you can place your rosin on right after pressing to speed up cooling.
As we mentioned earlier, there is a relationship between temperature and pressure. If you want to cold press (sub 200), you’ll need more pressure, and longer pressing duration.
Experiment and see if this produces better rosin for you, because in many cases, it may not. Excess pressure can result in issues of its own too, which we will detail below.
How much pressure do you need to press rosin?
The pressure needed will depend on the temps you use, but, also on what you’re pressing.
Flower needs more pressure, somewhere between 600-1000 PSI.
Dry sift/kief or hash will require less pressure because it is more concentrated. You should shoot for between 300-800 PSI.
Too much pressure can lead to a lower quality yield. You can actually end up squeezing plant matter into the rosin, resulting in impurities, poor taste, and overall lower quality.
The best rosin press machine
To find out which model is the best rosin press, you should consider your needs. You have personal-sized rosin press as well as those heavy commercial ones too.
These can be quite expensive, so you want to make sure you are getting what is right for you.
NugSmasher Mini Rosin Press
The NugSmasher Rosin Extraction System – Mini Smasher Version featuring 2 Tons of pressure and 2.5 inch pressing plates. It is ideally suited for pressing around 3.5 grams of material or less. Easy to use and suitable for family used. You can easily extract by yourself.
It is perfect for home users just getting started with extraction. You can press a ⅛ (3.5 grams) at a time with the 2.5” dual heated plates. The NugSmasher Mini may be small, but it can still produce up to 2 tons of pressure!
As with all NugSmasher rosin presses, this one is plug and play, features American steel and aluminum construction, and circuit protection.
The NugSmasher is manufactured in Corona, CA by Premiere Manufacturing in a 40k square foot machine and fabrication workshop staffed with experienced engineers, fabricators, designers and builders.

How to read a pressure gauge?
Pressure gauge readouts on air compressors, pneumatic cylinders, and hydraulic Rosin Presses are not the total pressure being applied. These are readings of the internal pressure system. Typical pneumatic/air systems usually go up to around 150 psi internal pressure, and typical hydraulic systems can go up to 10,000 psi internal pressure.
This must be translated to total force being applied! With conventional high end hydraulic systems, they operate on a 10,000 internal PSI basis. This means at 10,000 psi on the gauge, the cylinder will operate at it's full rated force. On our V2 Press, we use a BVA Low Profile 20 ton cylinder.
When you break that down: each 1,000 psi on the pressure gauge read out translates to 2 tons or 4,000lbs of force.
For another example, if you had a 30 ton cylinder, each 1,000 psi on the gauge would translate to 3 tons or 6,000lbs of force.
Simply put: Rated force of cylinder / 10 = Total Force per 1,000 psi on the gauge. This is a quick and easy way to calculate total force applied.
Conclusion
Getting the pressure right when making rosin has a huge impact on the overall quality of the finished product. Fortunately for you, the ECO Farm rosin press machine takes a lot of work out of the process and comes in a convenient size that is easy to operate and easy to move.
