Single vs Double Output Briquette Press

When choosing a briquetting press for metal chips, the first major decision is whether to go with a single output machine or a double output machine. AUPWIT offers both the Y85 single output series and the Y85-SC double output series, and the choice is not about which is objectively better. It is about which one fits your production volume, floor space, and budget.

The single output press produces one briquette per cycle, making it a proven workhorse for small to medium throughputs. The double output press produces two briquettes simultaneously per cycle, delivering higher throughput for large-scale operations. The key differences lie in throughput capacity, automation level, and long-term cost per ton.

So how do you decide? Below is a side-by-side comparison to help you match the right machine to your actual needs.

What Is a Single Output Briquette Press?

A single output press produces one briquette per cycle. That is the core mechanical distinction. The AUPWIT Y85 series single output models are proven, reliable machines designed for small to medium throughputs.

The Y85 series covers 10 sizes, from the entry-level Y85-50 up to the high-capacity Y85-630. All models operate at a system pressure of 25 MPa. Here is how the throughput scales across the range:

The single output design follows a straightforward operational rhythm. Material feeds into the hopper. The hydraulic system compresses it. One briquette is ejected. Then the cycle repeats. This simplicity translates into reliability and ease of maintenance, qualities that matter when you are running a machine across multiple shifts.

What materials can it handle? The single output press processes aluminum, magnesium, steel, copper, brass, and bronze. Light metals and heavier metals alike fall within its operating range.

Who is it for? Small workshops, machining centers, and medium-sized factories that need consistent briquetting without over-investing in capacity they do not yet need. The entry-level Y85-50, for instance, is specifically tailored for small chip volumes in metalworking fields, with throughput from 40 to 100 kg/h depending on the material.

What Is a Double Output Briquette Press?

A double output press produces two briquettes simultaneously per cycle. That is the headline feature. The AUPWIT Y85-SC series takes the same hydraulic principle and doubles the output without doubling the cycle time.

The Y85-160SC is the flagship model in this category. Its defining feature is a dual-discharge port system that allows two briquettes to be ejected at the same time. This design significantly reduces idle time between cycles and boosts overall throughput. The result is a throughput capacity of up to 800 kg/h for iron.

Here is how the Y85-160SC compares to its single-output counterpart, the Y85-160:

But the double output is not just about more briquettes. The SC series incorporates several design upgrades that make it suitable for high-volume, continuous operation.

Intelligent automation. The Y85-160SC integrates a Siemens touchscreen control panel with one-touch operation and a PLC control unit. This system provides real-time monitoring, automatic alarm functions, and data tracking. The machine runs itself with minimal operator intervention.

Mechanical grippers at the discharge ports. This might sound like a small detail, but this feature is important for high-speed operation. The grippers prevent briquettes from bouncing back during ejection. They ensure smooth, continuous discharge and minimize the risk of mechanical jams. In a high-throughput environment, a jam is not an inconvenience; it is a production stop.

Versatility across materials. Like the single output, the double output press handles the full spectrum: aluminum, magnesium, steel, copper, brass, and bronze. The difference is that it does this at a significantly higher rate.

Who is it for? Large-scale producers, foundries, and operations running 24/7. At Aluminium China 2026, AUPWIT exhibited both presses side by side. The double-briquette press generated strong interest among large-scale producers, and the reason is straightforward. When throughput matters more than anything else, the dual-discharge design delivers a tangible advantage.

Single Output vs. Double Output: A Direct Comparison

Now that we have covered each machine individually, let us put them side by side.

Throughput

Throughput is the most obvious difference. The single output Y85-160 delivers 180–280 kg/h for iron. The double output Y85-160SC delivers up to 800 kg/h. That is roughly three times the output from a machine with a similar footprint.

Cycle efficiency

The dual-discharge design means two briquettes per cycle instead of one. For a shop running multiple shifts, that difference compounds quickly. Less idle time between cycles translates directly into more tons per day.

Automation level

The SC series comes standard with Siemens PLC and touchscreen control. The single output models can be equipped with automation features, but the double output is built around them from the ground up.

Investment and ROI

ROI is where the choice gets interesting. The single output press has a lower upfront cost, with a smaller motor, simpler hydraulic system, and fewer components. For a workshop processing 200 kg per day, the single output is the sensible choice. For a factory processing 2 tons per day, the double output’s higher throughput converts into a lower cost per ton, which means a faster payback period.

Maintenance

Simpler machines are easier to maintain. The single output has one discharge port, one ejection mechanism, and fewer moving parts. The double output has two of everything. That is not a drawback; it is a trade-off. More throughput comes with more complexity, and that is worth factoring into your decision.

How to Choose: Matching the Machine to Your Operation

The decision between single and double output is not about which machine is better. It is about which machine fits your production volume, your space, and your budget.

Choose single output if:

• Your daily throughput is under 500 kg/day.
• You are a small workshop or machining center with limited floor space.
• You want a proven, low-maintenance solution with a lower upfront investment.
• You are processing a mix of materials and do not need maximum throughput.

Choose double output if:

• Your daily throughput exceeds 1 to 2 tons per day.
• You are running continuous, multi-shift operations.
• You want the lowest possible cost per ton over the long term.
• You value advanced automation and real-time monitoring.

There is also a middle ground. The single output Y85-500 and Y85-630, for instance, use dual motors, with 2×30KW and 2×37KW respectively. These models push iron throughput up to 1,500 kg/h. They blur the line between categories. They are single output in design but high-capacity in performance. For operations that need more than entry-level throughput but do not need the dual-discharge architecture, these larger single-output models are worth a close look.

Final Thoughts

Both the single output and double output presses from AUPWIT do the same fundamental job. They turn loose, messy metal chips into dense, valuable briquettes. The difference lies in the scale, the speed, and the level of sophistication.

The single output series is the reliable all-rounder, with proven technology refined across 10 different models. It is the machine you buy when you know what you need and you want it to work, day after day, without surprises.

The double output SC series is the high-performance option. It is designed for producers who have outgrown single-output capacity and need to push more tons through the door. It offers more machine, more automation, and delivers more output per hour.

So which one is right for you? Start with your daily throughput. If you are under 500 kg per day, the single output Y85-50 or Y85-80 will serve you well. If you are between 500 kg and 1.5 tons, the Y85-160 or Y85-200 are strong contenders. If you are over 2 tons per day and running multiple shifts, the Y85-160SC double output is where the math starts to make sense.

And if you are still not sure, that is what the technical team is for. Contact AUPWIT with your material type, daily volume, and current setup. They will walk you through the numbers and help you find the right fit.
