You may think a bigger number means a better machine. Many buyers make this mistake. They pay for power they do not need. Or they buy a machine that cannot make the bale they need.
The most important horizontal baler specifications are bale size, hydraulic pressure, compression force, and processing capacity. You must compare them together. A large pressure number alone does not make a good bale. You must match the machine to your material, storage, and transport needs.
This guide explains the main specifications. It shows how they affect real performance. It shows what you should check before you ask for a price.

What Bale Sizes Can a Horizontal Baler Produce?
You may not have enough space for large bales. You may not have a forklift that can lift them. You must pick the bale size first.
A horizontal baler can produce many bale sizes. The chamber sets the bale width and height. The bale length can often be adjusted. Confirm the real finished bale size, not just the chamber size.
A bale has three sizes. It has width, height, and length. The chamber fixes the width and height. The length can often change. Not every machine adjusts length the same way.
Always check the order the supplier uses. Some list width first. Some list length first. Ask for the finished bale size. A chamber number is not the same as a real bale. The real bale size decides if it fits your truck. It decides if your forklift can lift it.
Why Are Bale Weight and Density Important?
Bale dimensions alone do not tell you how much material a bale contains. Bale weight and density are also important. Two bales with the same dimensions may have very different weights. Material type, moisture, preparation, and compression conditions all affect the result.
Ask the manufacturer for the actual bale weight and size from a material test. You can also calculate bale density by dividing the bale weight by its finished volume.
Bale Density = Bale Weight ÷ Bale Volume
If weight is in kg and volume is in m³, the density is in kg/m³. This number helps you compare bales fairly. It also helps your recycling buyer.
For a practical comparison, use the finished bale's external dimensions after tying, not the chamber dimensions. A bale is not always perfectly regular. So treat the calculated density as an average apparent density.
| Material | Bale Check | Why It Matters |
|---|---|---|
| Cardboard and OCC | Bale weight and density | Must fit storage and truck space |
| PET bottles | Bale stability | Must hold shape after discharge |
| Plastic film | Bale density | Light film can make loose bales |
Do not assume plastic bales are always smaller. The final bale size and weight depend on the machine setup, the material, and the buyer's needs. Choose a bale that fits your full process.

What Is the Difference Between Hydraulic Pressure and Compression Force?
You may see a high pressure number. You may think it means a stronger machine. This is not always true. Pressure is only one part of force.
Hydraulic pressure is not the same as compression force. Force equals pressure times piston area. A large cylinder can make high force at lower pressure. A small cylinder may need high pressure to make the same force. Compare system pressure, cylinder force, and rated compression force together.
Pressure is the oil pressure inside the system. It is measured in bar, PSI, or MPa. Force is the push of the cylinder. You can calculate the force with a simple formula.
F = P × A. F is force. P is pressure. A is piston area.
When you calculate cylinder force, use the effective hydraulic pressure acting at the cylinder port under load. Do not assume that the pump's rated pressure or the relief-valve setting is the actual cylinder pressure.
For a double-acting cylinder, theoretical extension force is based on the full piston area. Theoretical retraction force is based on the annular area. The annular area is the piston area minus the piston rod area. This assumes the opposite port is at return pressure. Actual net force depends on the pressure at both cylinder ports and on mechanical losses.
Here is an example. This is only a math example. It is not a machine rating. Suppose the piston area is 0.0314 m². This equals a piston diameter of about 200 mm. The pressure at the cylinder is 20 MPa. The force is:
F = 20,000,000 × 0.0314 = 628,000 N = 628 kN
This is about 64 metric tonnes-force. This is the theoretical extension force at the stated cylinder pressure. Actual delivered force may be affected by mechanical friction and operating conditions. The machine's rated compression force must also be considered together with the frame, chamber, ram, and hydraulic system design.
You must know these terms. They are not the same.
| Term | Meaning | Why It Matters |
|---|---|---|
| System Pressure | Operating pressure in the hydraulic circuit | Confirm whether it is the normal or maximum pressure |
| Cylinder Force | Theoretical force produced by the cylinder | Helps compare hydraulic output |
| Platen Force | Force applied by the compression platen | Confirm the manufacturer's measurement method |
| Ram Face Pressure | Pressure applied over the ram face area | Helps assess pressure on the material |
Some factories list system pressure in one column. They list platen force in another column. They may also list ram face pressure. This proves that you cannot use system pressure as the machine compression force.
When you compare suppliers, check whether the manufacturer lists platen force, ram force, or ram face pressure. These terms describe different parts of machine performance. Do not treat them as the same number.

What Horizontal Baler Capacity Do You Need?
You may buy a machine that is too small. Then you work overtime. Or you buy one that is too large. Then you waste money. You must calculate your real need.
Horizontal baler capacity depends on material type, bulk density, feeding speed, cycle time, and tying time. Rated capacity is not the same as real throughput. Calculate your daily tonnage and your real working hours before you choose a model.
Capacity is often listed in tons per hour. But this number can be misleading. A machine may reach its rated capacity with cardboard. It may not reach the same number with film. Plastic film often has a low bulk density. So the machine may need more feeding cycles to build one bale. Real throughput depends on film condition, feeding method, chamber design, and the target bale weight.
You must calculate your own need. Start with your daily tonnage. Then divide by your real working hours.
Required Throughput = Daily Material Tonnage ÷ Effective Operating Hours
Daily material tonnage means the real weight of material you process per day. Effective operating hours mean the time available for real baling. Subtract planned breaks and expected downtime.
Here is an example. These are only planning numbers. Suppose you process 20 tons per day. You run 8 hours. The simple average is 2.5 tons per hour. But real work has stops. Loading stops. Tying stops. Material changes stop.
Suppose you estimate that the baler works 80% of the shift. The 80% is only a planning assumption. It is not a universal standard. Use your own records when possible. At 80%, you have 6.4 productive hours. Then you need about 3.125 tons per hour. So you must ask for a machine that can reach that rate with your material.
Add a reasonable operating margin for peak material supply and unexpected stoppages. Final machine selection should be based on a material test under realistic feeding and tying conditions.
How Does Material Type Change Real Capacity?
Different materials behave differently during feeding and compression. Loose cardboard can fill a lot of chamber space. Flattened cardboard may feed more evenly. PET bottles can trap air. They may need perforation or another air-release method. This depends on the bottle condition and the machine setup. Test the actual bottles before you choose the configuration.
Do not compare two machines by tons per hour alone. Check the test material. Check the test conditions. Check the bale size.
| Material | Main Capacity Risk | What to Test |
|---|---|---|
| Cardboard and OCC | Feeding consistency and bale weight | Actual tons per hour |
| PET bottles | Trapped air and bale stability | Bale weight and cycle time |
| Plastic film | Low bulk density and feeding problems | Feeding rate and real throughput |
Ask the supplier for a test with your material. Ask for the bale weight. Ask for the cycle time. Ask for the real tons per hour. A realistic number is better than a big number.

What Other Horizontal Baler Specifications Should You Check?
Bale size, force, and capacity are the main numbers. But other specs also matter. These details connect the machine to your real plant.
Check the feed opening, motor power, pump flow, cycle time, tying system, and machine dimensions. These specs decide if the machine fits your material, your power supply, and your floor space.
A machine can look good on paper. But it may not fit your building. It may not match your voltage. It may not feed your material well. Check the full picture.
| Other Specification | What Buyers Should Check | Why It Matters |
|---|---|---|
| Feed Opening | Size and shape for your material | Prevents feeding problems |
| Motor Power | kW, voltage, frequency, phase | Must match your power supply |
| Pump Flow | Rated flow and cycle speed | Affects ram speed and output |
| Cycle Time | Time per bale under real conditions | Shows real production speed |
| Tying System | Manual, semi-automatic, automatic | Affects labor and bale security |
| Machine Dimensions | Full size and installation space | Must fit your plant layout |
These specs turn the abstract numbers into a real machine. Ask for a drawing. Ask for the electrical data. Ask for the installation space. A good supplier will provide all of this in writing.
How Do Horizontal Baler Specifications Differ by Model?
Numbers become easier to understand when you see real model differences. Here is a reference comparison. Use it to see how force, power, bale size, and capacity change across models.
Model specifications show real differences in force, motor power, bale size, bale weight, and throughput. Use the tables below as a starting point, then confirm the current configuration and test your material before you buy.
Compression Force and Motor Power by Model
| Model | Compression Force | Motor Power |
|---|---|---|
| HBM-60 | 60 tf / 588 kN | 11 kW |
| HBM-100 | 100 tf / 981 kN | 22 kW |
| HBM-160 | 160 tf / 1,569 kN | 37 kW |
The force values above are metric tonnes-force (tf), with kN equivalents. The kN values apply only if the original rating is metric tonnes-force. Confirm the unit with the factory before you compare numbers.
Bale Size and Bale Weight by Model
| Model | Bale Size (W × H × L) | Approx. Bale Weight |
|---|---|---|
| HBM-60 | 1100 × 800 × 700 mm | 250 kg |
| HBM-100 | 1100 × 800 × 900 mm | 400 kg |
| HBM-160 | 1200 × 900 × 1100 mm | 550 kg |
Cardboard Processing Capacity by Model
| Model | Test Material | Reference Throughput |
|---|---|---|
| HBM-60 | Cardboard | About 1.5 t/h |
| HBM-100 | Cardboard | About 3 t/h |
| HBM-160 | Cardboard | About 5 t/h |
These figures represent selected model configurations. They are not the maximum capacity of the entire product range. Actual throughput depends on material condition, feeding method, operating cycle, and machine configuration. Confirm the rated values and test conditions with the manufacturer before ordering.
The tables show a clear pattern. A larger model gives more force. It also needs more motor power. It makes a bigger bale. It handles more material per hour. But the right model is not always the largest one. A small operation may not need a 160-ton machine. A large plant may need more than one machine. Match the model to your real tonnage and bale target.

Which Horizontal Baler Specifications Have the Biggest Impact on Price?
You may wonder why two machines cost very different amounts. The answer is often in the specifications. You must understand which specs drive the cost.
Bale size, compression force, pump flow, motor power, and the feeding and tying system have the biggest impact on price. A higher force can come from a larger cylinder area, higher working pressure, or both. Compare full configurations, not one number.
A higher compression force can come from a larger effective cylinder area. It can also come from higher hydraulic working pressure. It can come from both. The cylinder, pump, valves, circuit, frame, and chamber must work together safely.
Pump flow affects cylinder movement speed and cycle time. Hydraulic power demand is related to both working pressure and flow rate. For continuous or heavy-duty operation, the cooling system must also match the machine's working cycle.
A low price may exclude a conveyor. It may exclude automatic tying. It may use cheaper hydraulic parts. You must compare the same items.

Frequently Asked Questions
What Is the Difference Between Hydraulic Pressure and Compression Force in a Baler?
Hydraulic pressure is the oil pressure inside the system. Compression force is the push the machine applies to the material. Force equals pressure times piston area. So a large cylinder can make high force at lower pressure.
Can the Bale Length of a Horizontal Baler Be Adjusted?
Many horizontal balers can adjust the bale length. The method depends on the machine structure and the tying system. Ask the supplier how the length is set and whether it can be changed during operation.
Does Higher Compression Force Mean Higher Baler Capacity?
No. Higher force does not always mean higher output. Capacity also depends on pump flow, cycle time, feeding speed, tying time, and material type. Check the real test result for your material.
How Do You Calculate the Required Horizontal Baler Capacity?
Divide your daily material tonnage by your effective operating hours. Use real productive hours, not full shift hours. Then ask the supplier for a test with your material at that rate.
What Is the Difference Between Bale Size and Chamber Size?
Chamber size means the internal dimensions of the compression chamber. Finished bale size means the dimensions after compression and tying. The two numbers may differ. Always ask for the finished bale dimensions when you plan storage, forklift handling, and transport.
Does a Larger Hydraulic Cylinder Always Mean a Better Horizontal Baler?
No. A larger cylinder can make more force at the same pressure. But cylinder size alone does not decide machine performance. Pump flow, cycle time, hydraulic design, frame strength, and the material all matter too.
Conclusion
Bale size, pressure, force, and capacity work together. Check the real numbers and test your material. Contact Jukun for a horizontal baler that fits your needs.
