Overview
The Ermak HYB-Press 4100-220 is a large-format hybrid press brake from Ermaksan, combining conventional hydraulic cylinders with servo-electric drive technology to deliver 220 tonnes of pressing force across a 4,100 mm working length. This hybrid architecture is specifically engineered for heavy-gauge fabrication — structural steel components, thick plate forming, and long-length workpieces that exceed the practical capacity of pure servo-electric machines — while still delivering the energy efficiency gains that servo actuation provides over a fully conventional hydraulic design.
The HYB-Press series uses direct-drive servo motors to power the hydraulic pumps rather than a fixed-speed asynchronous motor, eliminating the constant idling losses of traditional hydraulic systems. This approach reduces energy consumption by 30–45% in typical production cycles and significantly reduces heat generation in the hydraulic oil, extending fluid life and reducing the frequency of oil changes. The large 4,100 mm bed accommodates tandem bending of long workpieces and complex part profiles that would otherwise require multiple setups or a dedicated tandem machine pair.
Frame rigidity at this scale is paramount, and the HYB-Press 4100-220 uses a heavily reinforced welded steel monoblock frame with integrated automatic hydraulic crowning. The crowning system reads deflection in real time and adjusts the bed profile dynamically during each stroke, compensating for the frame flex that is inevitable at 220-tonne loads on a 4,100 mm bed. The CNC control — a Delem DA-69T or Cybelec Touch 14 — manages crowning correction automatically without operator intervention.
The machine is targeted at structural steel fabricators, trailer and agricultural equipment manufacturers, wind tower component producers, and heavy industrial shops requiring consistent bending of plate up to 20 mm thick in mild steel. Ermaksan's ability to deliver this class of machine at a price point well below comparable German or Belgian competitors has made the HYB-Press series a popular choice in export markets across Eastern Europe, the Middle East, and Southeast Asia.

Strengths & Limitations
Strengths
- 220-tonne capacity on a 4,100 mm bed handles heavy structural plate bending that exceeds the range of most mid-size press brakes
- Servo-hydraulic hybrid drive cuts energy consumption by 30–45% versus conventional fixed-speed hydraulic press brakes at this tonnage
- Automatic hydraulic crowning compensates for frame deflection in real time, maintaining angle consistency across the full 4,100 mm working length
- Large throat depth of 500 mm accommodates deep-flange parts and complex profiles without interference with the machine frame
- Competitive acquisition price relative to equivalent-capacity machines from German and Belgian manufacturers
Limitations
- Machine weight of approximately 28 tonnes requires a reinforced concrete foundation and heavy-lift crane for installation
- Servo-hydraulic hybrid is more maintenance-intensive than pure servo-electric press brakes, retaining hydraulic fluid, seals, and filter service requirements
- At this size class, Ermaksan's global service network may not provide the response times available from manufacturers with larger international presences

Frequently Asked Questions
01
At full 4,100 mm working length, the 220-tonne capacity can bend mild steel plate up to approximately 12 mm for a 90° bend. At shorter working lengths using partial tooling, bending capacity increases accordingly. Stainless steel and high-strength steels reduce the effective capacity by a factor of 1.5–2× depending on tensile strength.
02
The machine is not natively designed for electronic tandem synchronisation with a second unit. For true tandem operation on parts longer than 4,100 mm, Ermaksan can quote a dedicated tandem pair with synchronised CNC control. However, for most 4,100 mm workpieces, the single machine is sufficient.
03
Hydraulic cylinders embedded in the bed are controlled by the CNC to create a pre-calculated convex deflection profile that opposes the expected frame deflection under load. The crowning profile is automatically calculated from the programmed tonnage and tooling length, and can be fine-tuned based on measured angle results in the first bends.
04
The machine requires a reinforced concrete foundation pit or plinth designed for a point load of approximately 28 tonnes. Foundation drawings are provided by Ermaksan as part of the pre-installation documentation package. Minimum floor loading capacity should be verified by a structural engineer before installation.
05
Yes. Ermaksan supports robotic tending integration and has worked with leading robot integrators to automate HYB-Press machines for repetitive heavy-plate bending applications. The machine includes the necessary I/O interface and safety zones for robot cell integration, though the robot and gripper system are supplied separately.
