Let’s dive deeper into what a hydraulic press actually is and why Qnubu’s models, especially the newly released Cold Brick 4 Tons Manometer Press, are turning heads.

What Is a Hydraulic Press and How Does It Work?

A hydraulic press uses hydraulic cylinders to generate a compressive force. It works based on Pascal's Law, which states that pressure applied to a confined fluid is transmitted uniformly in all directions. In simpler terms, a small amount of force applied to a small piston can create a massive force on a larger piston—ideal for compressing plant material for rosin extraction.

Here’s how it works:

1. The user loads plant material into a parchment paper envelope or a pressing bag.

2. The loaded material is placed between the heated plates of the press.

3. The hydraulic mechanism applies intense pressure to the plates, squeezing the plant material.

4. The combination of pressure and (sometimes) heat extracts the rosin from the plant matter.

5. The golden, sticky rosin oozes out and is collected on the parchment paper.

What makes hydraulic presses particularly attractive is the high level of control and force they offer. This method ensures a better yield and a cleaner extract compared to manual pressing methods. Hydraulic presses like those from Qnubu allow you to extract more efficiently, maximizing your material and minimizing waste.

For extractors who want precision, consistency, and power, hydraulic presses are the go-to. And among the many available, Qnubu’s models, particularly the Cold Brick 4 Tons Manometer Press, are shining examples of what cutting-edge pressing technology should be.

Cold Pressing vs. Hot Pressing: What's the Difference?

When it comes to rosin extraction, both cold pressing and hot pressing are popular techniques, each with its own unique set of benefits and outcomes. Choosing the right method often depends on what you prioritize—flavor, potency, or yield.

Cold Pressing:
This method involves using lower temperatures (usually between 160°F–190°F) and longer pressing times. Cold pressing tends to preserve more of the plant’s terpenes and flavonoids, which means the end product is often more aromatic and flavorful. However, the yield can be slightly lower compared to hot pressing. It’s a great method for connoisseurs who prioritize taste and smoothness over sheer quantity.

Hot Pressing:
Hot pressing uses higher temperatures (typically around 190°F–220°F) and shorter pressing times. This method often results in a higher yield, as the heat helps loosen and release more oils from the plant material. While some terpenes may be lost in the process, the end result is usually more potent and abundant.

With the Qnubu Cold Brick 4 Tons Manometer Press, users have the ability to cold press with incredible control and consistency. The inclusion of a manometer and the ability to exert 4 tons of pressure ensures that even at low temperatures, you’re getting an optimal yield with minimal degradation of quality.

This flexibility means you can experiment with both methods and find what works best for your material and your preferences.

Whether you’re new to pressing or looking to upgrade your setup, the Qnubu Cold Brick 4 Tons Manometer Press brings professional-grade performance into the comfort of your home.

How to Use the Qnubu Cold Brick Press Step-by-Step

Using the Qnubu Cold Brick 4 Tons Manometer Press is surprisingly straightforward, even if you're just getting started with rosin extraction. The machine’s intuitive design makes it easy for beginners, while still providing the level of control that professionals crave. Let’s break it down into a simple step-by-step process to help you get the most out of your press.

Step 1: Prepare Your Material

Start by selecting your source material—this could be dried flower or kief. Make sure your material is clean, free of contaminants, and properly cured to ensure optimal yield and quality. If you're pressing flower, you might consider pre-pressing it into a puck using a mold to ensure an even distribution of pressure during the extraction.

Step 2: Choose the Right Filter Bag

Next, select a rosin filter bag that suits your material. These come in different micron sizes—ranging from 25 to 160 microns—with lower numbers better suited for finer material, and higher numbers for flower. Load the bag evenly and seal the ends to prevent blowouts during pressing.

Step 3: Preheat and Set Temperature

Plug in the Qnubu Cold Brick Press and set your desired temperature on the control panel. For cold pressing, aim for 160°F to 190°F; for hot pressing, 190°F to 220°F is standard. Give the plates a few minutes to reach the selected temperature.

Step 4: Position and Press

Place your loaded bag between two sheets of parchment paper and center it between the heated plates. Slowly begin applying pressure using the hydraulic handle. Use the integrated manometer to monitor pressure levels. Apply steady, even pressure—don't rush this step.

Step 5: Extract and Collect

As pressure builds, the rosin will start to seep out onto the parchment paper. Hold the pressure for 60–120 seconds depending on the material and temperature. Once done, slowly release the pressure and remove the parchment. Carefully collect the rosin using a dab tool and store it in a cool, dark place or an airtight container.

Using this press consistently will help you perfect your technique. Over time, you’ll learn which temperatures and pressures yield the best results for your specific strains and materials.

Comparing Qnubu Models: Which One Is Right for You?

Choosing the right Qnubu press depends on your specific needs, whether you’re a casual enthusiast or a serious extractor. Luckily, Qnubu offers a wide range of models, each designed with unique features and use cases in mind.

Manual Presses

Manual models are the most affordable and beginner-friendly. These typically don’t include hydraulic or pneumatic features and are best for small-batch users. They require a bit of elbow grease but are excellent for users who want control without investing heavily.

Best For:

• Home users

• Small volume extractions

• Tight budgets

Hydraulic Presses

These are powered by hydraulic pistons and require less manual effort than the manual models. The Qnubu Cold Brick 4 Tons Press falls into this category. It’s compact, powerful, and ideal for users who want precise control without going full-auto.

Best For:

• Intermediate to advanced users

• Consistent yield with less effort

• Mid-sized batch production

Pneumatic and Electric Presses

These high-end models are for serious extractors. They automate much of the process, ensuring uniform pressure and temperature with minimal manual input. Great for businesses or heavy-use scenarios.

Best For:

• Commercial use

• High-frequency pressing

• Those needing maximum consistency and speed

Whether you're just starting or looking to expand your operation, Qnubu offers a model to match your workflow and budget. For most users, the 4 Tons Manometer model hits the sweet spot of power, portability, and precision.

Benefits of Using a Rosin Press at Home

With more people exploring at-home extraction, a personal rosin press has become an essential tool for connoisseurs. Let’s explore why owning a Qnubu press is a smart investment for both recreational users and medicinal patients.

Solventless Extraction – Cleaner and Safer

Traditional extraction methods often involve solvents like butane or CO₂, which can leave chemical residues in the final product. With a rosin press, you get solventless extraction—just heat and pressure. This results in a cleaner, purer product that’s free from harmful chemicals.

You’ll never have to wonder about what’s in your dabs again. What you press is what you get—pure, natural, and effective.

Control Over Quality and Yield

Pressing at home gives you full control over the process. You choose the strain, the temperature, the pressure, and the duration. Want more flavor? Press cooler. Want a bigger yield? Bump up the heat. It’s like cooking your favorite meal just the way you like it, rather than buying something pre-made.

Plus, you can experiment. Try different microns, bag techniques, pressing times—dial in what works best for you and your material.

Cost Savings Over Time

Let’s face it—buying top-shelf rosin isn’t cheap. But once you own your press, your only costs are raw material and parchment. Over time, you’ll save a significant amount while enjoying a better, fresher product.

In short, pressing your own rosin at home isn’t just a hobby—it’s a lifestyle upgrade.
