How much pressure does it take to make rosin? Guide for Beginners
How Much Pressure To Make Rosin?
A lot of people who make their own rosin press machine get 20-ton jack presses, because they think more pressing power is better. That is not quite true.
The figure that is important is psi (pounds per square inch) at the bag. The overall pressing power of a press is only one factor that affects psi at the bag.
Another factor is the size of the rosin bags (which is obviously also related to the size of the pressing plates). The ideal plates and bag are long and narrow. A rectangular shape gives you more perimeter (where the rosin can escape the bag) and less area in the middle (where the rosin can get stuck).
Rectangular bags thus give you better yields from a smaller pressing area, i.e. the total size of the bag in square inches (or square centimeters). And since the surface area of the bag is smaller, you need less overall pressing power to deliver the required psi.
How to calculate Platen PSI for your Rosin Press:
Platen PSI is simply calculated by taking the total force and dividing it by the size of your bag, not the size of your plates. In this instance, we’ll say you are maxing out our 4x7 V2 Lowtemp Press (20 ton capable) with a 3"x6" bag of material. For round numbers, we’ll say you’re utilizing half of what the cylinder can generate: 10 tons (2,000lbs per ton), or 20,000 lbs of force.
3"x6" pouch= 18 square inches
10 tons of force= 20,000lbs of force
20,000 lbs / 18 sq in = 1,111 Platen PSI
