how to make a small hydraulic hash press

Pressing plant products through a hydraulic rosin press produces higher quality extractions with more consistent results, but purchasing one commercially manufactured hydraulic press may be expensive.

Homemade hydraulic hash presses are relatively inexpensive to assemble and provide a simple DIY project for rosin enthusiasts.

How to Build a Hydraulic Hash Press

Hydraulic hash presses are an efficient and cost-effective way of producing superior hashish. Constructed from aircraft aluminum for optimal heat retention and featuring step by step instructions on their use, these hydraulic presses come complete with everything you need for successful hash production. You can purchase additional rods to customize the size of your press, as well as stamps designed specifically to create pipes from cannabis!

Practice makes perfect, so the best way to ensure consistent rosin extractions is to complete several pressing sessions and get used to the process. This will give you a sense of what it's like as well as allow you to experiment with variables like preheating temperatures, pressure levels and press timing - this way your learning curve can accelerate over time! Record results as they occur so you can compare and accelerate it over time!

Build your own hydraulic-based rosin press. This DIY project requires a short-body hydraulic bottle jack and force gauge filled with glycerin that's rated to 2000 PSI; these components connect via 1/4-inch NPT male bottom-fittings which connect directly into your press' ram.

Pneumatic-based rosin presses offer another viable option, operating similarly to hydraulic presses but using compressed air rather than compressed fluids as pressure generators in their cylinder. Pneumatic presses tend to be less expensive than their hydraulic counterparts and require minimal maintenance costs; making them an excellent option for first-time cannabis extractors or growers looking to increase precision during rosin production.

To prevent blow-outs, the key is minimizing how much material is placed into each mesh bag. Fill your bags only halfway to avoid overfilling them, gradually apply pressure while warming your materials before applying full force pressure - these tips should get you on your way to producing high-quality solventless hash!


As cannabis concentrates have grown increasingly popular, small hydraulic presses have experienced an upsurge in demand. These typically consist of C-frame steel construction and require less floor space than other press machines. Small hydraulic rosin presses use hydraulic fluid pressure to generate pressure that is transferred downward via insulated rosin plates which are compressed using hand pumps (usually sold separately) until forced exerted on these plates is variable over time for different extraction needs.

Hydraulic rosin presses use no chemicals to produce solventless cannabis concentrates, instead relying solely on heat and pressure to produce bubble hash loaded into a filter screen bag called a "rosin bag" until its pressure causes its trichome heads to burst under pressure before running out through parchment paper for collection. The result is an all-natural product ranging from soft crumbly buds to dark brittle shatter with varied effects.

To build your own DIY hydraulic hash press, you'll require a large metal box, some flat aluminum that can be cut to size for the lid and bottom of the box, two stainless steel pressing plates, two insulated rosin bags without plastics that leak during extraction, as well as a hand-held hydraulic jack. All these materials can be found at home improvement stores or online; just be sure that when selecting medical-grade bags that contain no plastics that could potentially enter your vapor stream during extraction.

Rosin bags from Rosinator or Neato presses can also be purchased pre-pressed, although these may be more costly. Some pre-pressed bags include special coatings to minimize vapor loss during extraction and can even be reused multiple times before being thrown away.

Once you have all your parts together, begin by filing the internal weld seam of the box section with a file or bench grinder so the pressing plates fit snugly against its edges. Next, lightly coat each pressing plate in cooking oil to prevent against rust and act as release agents when pressing hashish.


H-frame hydraulic presses are an increasingly popular option among home users, thanks to a hydraulic pump driving pistons into an anvil or base plate to compress material sourced from either kief or whole plant cannabis. Manual and electric models of H-frame presses exist with capacities, powers and automation options that vary according to capacity, power consumption and automation needs; electric models tend to be more user-friendly due to their quiet operation compared with pneumatic ones in shared space environments.

To maximize your yield, select appropriate size rosin bags and press at an optimal temperature range (78-90 degrees Celsius is best for pressing kief, dry sift or hash). Higher temperatures produce darker more crumbly rosin while lower ones yield lighter more liquidy products.

Pressing rosin generally takes 30 seconds; however, this time may differ depending on strain and press capability. Furthermore, to minimize blow-outs by packing less hash into each bag, reduce blowouts by packing lightly, use larger mesh rosin bags for storage, allow material to warm up before applying pressure, and use larger mesh rosin bags that allow material to heat up before pressing pressure.

Once you've successfully navigated the initial setup process and acquired basic equipment, it is critical to understand all the variables influencing rosin production. Time, temperature, and pressure during extraction will impact terpene profiles and cannabinoid content of your final product; additionally it is vital that you understand how best to store and handle solventless concentrates for optimum quality results.

Once you've mastered rosin production, the next step should be creating pressed hash or flower, also known as pucks or coins. These small pellets are frequently used to combine different strains of marijuana together or store for later consumption - they're great additions to joints or pipes to elevate user experiences! Stored away from sunlight they should last several months. Also easier than buds themselves to freeze.


A hydraulic hash press (also referred to as "pollen press") uses a short-body hydraulic bottle jack with an integral force gauge filled with glycerin for use as a home extraction machine for solventless cannabis extraction. It's best used to produce high-grade rosin from bubble hash or whole plant cannabis, though other concentrates may also be processed using this press. Getting high-grade results requires patience and following directions closely for successful rosin creation.

Most commercial rosin presses utilize pneumatically powered pumps to generate pressure, while some artisan hash makers prefer hydraulic presses due to their precision and ease of use. Similar to an oil pan or car radiator, hydraulic rosin presses feature parchment-lined cylinders for ease of filling with hashish, kief or plant material that needs compression; once filled these are hit with mallets until desired amount has been tightly packed; finally using a hand crank, operator then removes their product from bottom platen by operator using hand crank.

Homemade hydraulic hash presses can be made using recyclable items such as car radiators, oil pans and drums from old cars, or made entirely out of aluminum for maximum durability. Once assembled, it should be carefully cleaned to eliminate burrs or sharp edges before being coated in cooking oil to protect from rusting and act as a release agent. Some rosin makers opt to purchase small hydraulic presses rather than build their own as these tend to be easier and cheaper to assemble.

Once you have the proper equipment in hand, it's time to begin crafting rosin. First step should be warming and pre-pressing the rosin bag, in order to compact material and eliminate inconsistencies that lead to poor yields. While pre-press molds can be purchased online retailers such as Amazon or even Food-grade aluminium foil can often do just as well and is significantly cheaper.

An additional helpful tip when pressing rosin is gradually ramping up pressure after stamping it into bags. Applying full pressure all at once increases the risk of bag ruptures and yield decreases, potentially compromising yields and diminishing quality.
