DIY Rosin Pressing involves an H-frame hydraulic press and set of rosin plates; this solution offers both cost-efficiency and customization of press setup.

Apply pressure gradually rather than all at once; this helps avoid sudden bag blowouts and maintain even pressure throughout the press cycle.


To properly press bubble hash rosin, it is crucial that pressure be evenly applied throughout the extraction process. Too much or too little pressure could result in a blown bag requiring additional cleaning time and speeding up degradation of rosin. For best results, we advise starting out slowly before gradually increasing pressure as you become familiar with your equipment and extraction procedure.

Small hydraulic hash presses can be easily assembled using materials available at home improvement stores or online. They're often preferred because of their minimal maintenance requirements and lower cost compared to large commercial presses, and tend to feature parchment-lined cylinders where hashish, kief or plant material can be loaded before being hit with a mallet until all product has been tightly compressed into place.

The cylinder is then placed within a homemade hydraulic press and connected to a short body hydraulic bottle jack and force gauge rated for 2000 psi, filled with glycerin and calibrated at 2000 PSI. A 1/4-inch NPT male bottom-fitting screws directly into the press' ram to facilitate pressure readings.

Hydraulic hash presses are ideal for larger commercial operations, while some artisan extractors prefer manual machines as a more precise means to increase precision when pressing cannabis with high levels of trichomes. Though more labor-intensive than pneumatic presses, manual machines offer more control over force applied to each plate - an advantage when pressing cannabis with abundant trichomes.

One advantage of this type of system is that its components can be tailored specifically to a user's requirements and needs, enabling him or her to customize how much pressure is applied to each plate and create optimal conditions for pressing. This feature is particularly advantageous when starting out making rosin, since inexperienced hands often overpress their material, leading to ruptured bags and consequently losing precious rosin in the form of waste material.


Pressing hash rosin, an extremely potent solventless concentrate, requires temperatures that reach the ideal thresholds to allow trichomes to burst and dissolve, releasing oils through parchment paper into collection cups and out of your rosin bag. Being an adept presser requires practice; let us now review some tips that can help maximize rosin production for high-quality extractions.

Pressing bubble hash, dry sift or ice water hash requires temperatures ranging between 160F and 220F for optimal results. For accurate temperature readings it's advisable to utilize an infrared thermometer; these handy devices are affordable and simple to operate - however cleaning them may prove challenging compared to standard thermometers.

For optimal results, it is advised to preheat the plates prior to applying any pressure. This will help ensure an even heating of the rosin bag and minimize any blowouts or leaks from its contents.

Start out slow when applying pressure, gradually ramping it up over the duration of the press. Too much pressure all at once may disrupt consistent flow, increasing risk of bags sliding between heat plates or blowing out completely.

Many rosin enthusiasts have experimented with using ordinary hair straighteners to produce rosin, but in order to extract high-grade rosin from buds or hash it requires greater precision and power - something only hydraulic rosin presses are designed to do effectively, however these investments tend to be more costly than homemade solutions.

Small-scale rosin producers should also consider investing in a pneumatic rosin press, which uses air compressors to generate pressure and can often be easier than their hydraulic counterparts to use. They do require more maintenance and can be loud, though; so some producers opt for traditional hydraulic presses. No matter which press you choose, investing in some rosin bags is highly recommended in order to get maximum benefit out of it.


Hydraulic hash presses have quickly become one of the go-to solutions in solventless cannabis extraction methods like rosin hash, bubble hash and ice water hash production. As these DIY models produce high-quality concentrates using heat and pressure alone - even for novice extractors - choosing an appropriate model can be daunting given its wide selection of designs and prices available on the market.

An essential hydraulic rosin press can be operated using a hand-pumped lever system which raises hydraulic pressure inside of a cylinder while feeding its increased force into a hose with an oil-filled liner, and eventually driving force applied to rosin plates. To increase efficiency of this press system, an air pump can also be added so as to convert compressed air into the force necessary to push together the rotating cylinder and plates together.

Though press your own rosin can bring many advantages, not everyone wishes to invest in and learn how to operate an expensive hydraulic hash press. As an alternative solution, manual presses are available which make making quality rosin easier than ever.

A common type of rosin press is a basic box-style design wherein starting materials, such as sieved skuff or other starting material can be placed between two heated plates and packed tightly enough that they cover its entirety. Plate one is typically lined with foil or paper for packing purposes before materials can be packed on to cover its entirety; when this has been accomplished you can slide plate two over it.

Once the skuff is in the press, be careful not to overfill it or you risk creating a block of hash that won't fit into your rosin bag when compressed. Carefully place the second plate and slowly pump until lifting up on it with hands becomes impossible; repeat until all four plates have produced a solid hash block without too much thickness for use in your rosin bags.


Safety precautions must be implemented for every piece of equipment to avoid accidents and injuries, from crushing injuries from contact with machine parts to electrical hazards from power systems and chemical exposure from lubricants and hydraulic fluid. In order to protect workers, some steps must be taken.

Use of appropriate equipment and procedures can help protect against serious injury, for instance a high-quality hydraulic rosin press is specifically designed to be durable yet user friendly, featuring arc-welded frames with seamless steel cylinders to minimize leakage; in addition, its lower center of gravity makes it simpler to control and maneuver.

Understand what force is necessary for optimal extraction results and gradually apply pressure with light touches in order to prevent bag slippage. Excessive force applied too rapidly could rip or crack the bag, spilling out rosin.

Temperature adjustments of your press should depend on the quality and age of your starting material. High quality flowers harvested fresh require less heat for extraction while older or denser material requires additional heat to break down its trichome heads, in order to maximize yield while minimizing raw material waste.

Blowing outs are another potential danger when applying too much pressure to the rosin bag, leading it to rupture between heating plates. This can compromise your extract by spilling unfiltered rosin onto parchment paper. Therefore, it is vital that pressure spikes are monitored during this process and the ram speed adjusted accordingly.

Although there are various physical safety products that can be used to safeguard employees, one of the most efficient is a ballistic protection blanket. Specifically designed to offer additional safety during hydraulic press operations and contain broken or flying parts that might otherwise pose harm, as well as prevent accidental exposure to hydraulic fluid, it provides a cost-effective way of meeting machine guarding standards and meeting machine guarding standards. An interlock kit may also come in handy by keeping ejection curtains closed during operations.
