There are actually a number of different types of rosin presses which you can make or buy.
* DIY Rosin Press: If you have a hair straightener and a clamp, believe it or not, that is all you really need to make a basic rosin press. You also need some parchment paper, a tool to use to collect the oil, and gloves to protect your hands from the heat. Alternately, you can modify a hydraulic shop press by adding heat plates and use that instead.
* Manual Rosin Press: If you want to keep operation simple and costs down low, consider purchasing a manual press. These devices tend to be smaller than their hydraulic counterparts (see below), so they offer the advantage of portability. You operate them using a hand crank.
* Hydraulic Rosin Press: With this type of press, you use a hand pump to produce hydraulic pressure. They are reasonably portable, and offer a kind of “in-between” option between a manual and pneumatic press.
* Pneumatic Rosin Press: This type of press is basically like a hydraulic press, but it includes an extra feature in the form of an air compressor. This frees you from manual labor. There is no cranking and no pumping. You can adjust the pressure level precisely just by pressing a button. Because of the air compressor, portability is limited.
* Electric Rosin Press: This type of press gets you away from pumps and compressors altogether. Powered through a basic wall outlet, the electric rosin press offers convenience and ease of use and is ideal for processing large batches.
* Hybrid Rosin Press: This type of rosin press is designed for large scale commercial use, and offers ultimate flexibility. It can run pneumatically or electronically, or you have the option of using a pump manually if you prefer.
