DIY Rosin Press (Plates Mounted To Generic Press) Complete Guide

DIY Rosin Press Guide

Building a do-it-yourself rosin press is easier than it sounds.

That's why many choose to make their own press at home rather than buy a dedicated model.

You can save a good amount of money, even if you buy a set of pre-fabricated heated plates and don't make that component yourself.

You can save more if you also build your own plates, but we don't feel doing so is worth the effort for most people.

If you have the tools needed to cut and drill metal, then it might make sense for you.

For the rest of us, it's much easier to simply buy a set of DIY plates that come pre-fabricated and include the heating elements and controller needed to heat the plates to the correct temperature.

This is what we are going to cover in this guide.

If you are looking to make a rosin press out of a hair straightener, we can help with that as well. We don't cover it in this article, though, since a hair straightener is only good for making very small amounts.

This guide is for people looking to extract on a slightly larger scale, either for personal use or even for commercial production.

Nevertheless, we did create a step-by-step guide for pressing rosin with a hair straightener. At the moment, we are just giving it away for free. If you're looking to start out with a hair straightener (as most do, to be perfectly honest), simply enter you email address below and we'll send you a copy of our guide.


DIY Rosin Press: What You'll Need

You really only need two things, unless you want to make your own plates (not recommended unless you already have the tools to cut and drill metal):

  • A set of heated plates
  • A shop press

What type you want depends on how powerful a press you plan to build. The best way to approach this is to decide how much material you plan on processing.

Below are 4 common plate sizes with information about how much you can expect to process and how much pressure is ideal for each size.

Ideal pressure is based on the ideal PSI (pounds per square inch) for pressing rosin. The ideal PSI is between 300 and 1000, depending on the material being pressed, as shown in the graph below.

Ideal pressure for DIY rosin

To calculate the ideal pressure, we start with the target psi. We'll go with 1000 psi, since that is the maximum needed to press any type of material. Note that some people feel more pressure is better. If that is the case, go ahead and use a higher psi for your calculation.

We need to multiply the psi by the size of the filter bag or material (if no bag is being used) in square inches. We do NOT use the size of the plates, since all of the pressure comes to bear on the bag or material, not on the plates.

That said, if you're not sure yet what your bag size will be, go ahead and use the size of the plates, since you know that the bag or material being pressed will always be smaller than the plates.

Let's take the 4 by 4 inch plates as an example. Those plates are 16 square inches in size (4 x 4 inches). With a target psi of 1000, we'd need a press that can deliver 1000 x 16 = 16000 pounds. 16000 pounds = 8 tons, so we'd want a press that can deliver 8 tons of pressure at a minimum.


Rosin Plate Sets

A DIY rosin plate set includes these components:

  • two plates
  • heating elements for the plates (the number varies, depending on the size)
  • digital controller for the heating elements
  • wires from heating elements to controller
  • power cord for controller
  • adapter plate to connect plates to press


The following are 3 common plate sizes.

3 by 4 Inch Plate Set

See it here. *

  • Power: 610 W
  • Max Pressure: up to 30,000 lbs / 15 Ton
  • Max Temperature: 450 °F / 232 °C
  • Ideal Use: home/personal

3 by 6 Inch Plate Set

See it here.*

  • Power: 700 W
  • Max Pressure: up to 40,000 lbs / 20 Ton
  • Max Temperature: 450 °F / 232 °C
  • Ideal Use: personal or small commercial

3 by 8 Inch Plate Set

See it here.*

  • Power: 1010 W
  • Max Pressure: up to 60,000 lbs / 30 Ton
  • Max Temperature: 450 °F / 232 °C
  • Ideal Use: personal or small commercial



    The rosin plate sets above mount to just about any standard press. The best options for home use are an arbor press or a hydraulic shop press.

    For commercial production, we recommend a pneumatic press. They are louder (since they require an air compressor), but operate faster and more accurately.

    One thing to note is that these presses last much longer if they are not used at their full capacity. This means that using a 20 ton press at 10 tons maximum will greatly increase its lifespan over using it at the full 20 tons.

    For that reason, we always recommend getting a press with a higher maximum pressure than you need, but never running it at the maximum pressure.

    Here are our recommendations for pressing power:

    • 3 x 4 plates: 3 to 15 tons
    • 3 x 6 plates: 10 to 20 tons
    • 3 x 8 plates:  15 to 30 tons

    Which Press Brand Is Best

    As mentioned, you can use just about any press, so go ahead and see what is available locally. Alternatively, you can buy a press online from Amazon or elsewhere.

    If you are looking for some brand recommendations, many rosin pres DIYers swear by the Harbor Freight presses, because they are inexpensive. The problem is a poor build quality. These presses are made to be used occasionally and will not last long if they are being used daily.

    If you have a larger budget, you'd be much better off getting a higher quality press, like a Dake. Dake presses are the second most popular brand after Harbor Frieght for homemade rosin presses. They cost more, but are much more solid and reliable.

    Here is Amazon's selection of Dake presses (note that Baleigh and Grizzly are both rebranded Dake presses). *

    A third option is Strongway. They occupy the space between Harbor Frieght and Dake and offer a good compromise between price and build quality. We definitely prefer the Dake presses, but if they are out of your budget, Strongway is a good option.

    Here are the Strongway presses on Amazon. *


    Building Your DIY Rosin Press

    This part will be shockingly short.

    All you have to do is mount the plates to the press and you're done. It really is that simple!

    And with that, you're ready to press some rosin! If you're not sure how to do it, we have a guide that covers every step.
