WyBend G Series Extra-Large Sheet Metal Press Brake

The WyBend G Series is an extra-large heavy-duty CNC press brake of exceptional capacity, available in 5 configurations — from the G 1000 (10,000 kN / 1000 tonnes, 6000 mm) up to the G 5000 (50,000 kN / 5000 tonnes, 15000 mm) — designed for the shipbuilding, heavy-construction and infrastructure industries that process sheets and metal profiles of dimensions and weights impossible to process on any other equipment in the WyBend family. With a reinforced 300HB+ steel frame with a dedicated reinforcement kit, a high-capacity Parker / Bosch Rexroth hydraulic system and a CNC deflection-compensation system for extra-large formats, this extra-large sheet metal press brake represents the largest bending equipment in the UZINEX portfolio.

The WyBend G 5000 model with a force of 5000 tonnes and a working length of 15 meters is a huge piece of equipment — 20×10×15 meters — intended exclusively for industrial bending operations at a naval or heavy-infrastructure scale. The ultra-rigid frame with an additional Fibro Customize reinforcement kit provides the structural rigidity needed not to geometrically deform the machine under the forces of tens of thousands of kilonewtons applied over lengths of 10–15 meters.

Key advantages of the WyBend G Series extra-large sheet metal press brake

• Bending force 1000–5000 tonnes — extreme industrial capability — the WyBend G Series extra-large sheet metal press brake far exceeds the capacity of the H series (max 800 tonnes), with the G 3000 and G 5000 models at 3000 and 5000 tonnes respectively covering the bending of ultra-thick sheets (50–200 mm) in the shipbuilding industry and heavy construction, impossible to process on any standard press brake.

• Working length up to 15000 mm — 15-meter parts — the G 5000 model of the extra-large sheet metal press brake processes parts up to 15 meters long, covering the complete sections of ship hulls, bridge beams and extra-long industrial structures that cannot be processed in steps without intermediate joints.

• Reinforced 300HB+ frame with a dedicated reinforcement kit — the ultra-rigid frame of the WyBend G Series extra-large sheet metal press brake is made of 300HB+ steel with a Fibro Customize reinforcement kit additionally applied in the critical maximum-stress zones, ensuring that the machine geometry does not permanently deform under the forces of 10,000–50,000 kN applied repeatedly in continuous production.

• High-capacity Parker / Bosch Rexroth hydraulic system — the high-capacity Parker and Bosch Rexroth hydraulic pumps provide the flow and pressure needed to drive the cylinders at forces of 1000–5000 tonnes with a fast response and constant pressure over the entire 6000–15000 mm length.

• Large-scale CNC crowning system — uniformity over 15 meters — the automatic deflection compensation for extra-large formats calculates and applies the crowning over lengths of 6000–15000 mm, ensuring that the bending angle is uniform over the entire part length even at forces of 5000 tonnes where the deflection without compensation would be several centimeters.

• Back gauge with extensions for extra-large formats — ±0.02 mm — the dedicated extensions of the HIWIN back gauge allow precise positioning of extra-long materials with ±0.02 mm accuracy, even at the large distances from the bending axis typical of 10–15 meter long sheets.

• Follow-up sheet support for extra-long sheets — the follow-up sheet support synchronized with the beam movement assists the handling of sheets weighing hundreds of tonnes over lengths of 6000–15000 mm, preventing sheet flexing under its own weight outside the bending zone.

Technical specifications of the WyBend G Series extra-large sheet metal press brake

WyBend G versus WyBend H — from 800 tonnes to 5000 tonnes

The WyBend H Series with a hybrid servo system and forces of 300–800 tonnes is the solution for standard heavy industry. The WyBend G Series extra-large sheet metal press brake covers a completely different segment — 1000–5000 tonnes — where there are no alternatives in the UZINEX portfolio and where equipment up to 800 tonnes is undersized for the thicknesses and lengths of the processed sheets. At forces of 1000 tonnes and above, the fixed Parker/Bosch Rexroth hydraulic system is chosen over the hybrid servo system for maximum reliability under extreme, continuous loads.

Applications and industries for the WyBend G Series extra-large sheet metal press brake

The WyBend G Series extra-large sheet metal press brake is intended exclusively for industries that process ultra-thick sheets and profiles of exceptional dimensions. Shipyards use the G 2000–G 5000 models for bending hull profiles from 50–100 mm thick naval-steel sheets over lengths of 10–15 meters — specifications impossible to cover with standard 800-tonne press brakes.

Producers of equipment for the extractive industry — mining excavators, crushers, industrial conveyors — use the G 1000 and G 1500 models of the extra-large sheet metal press brake for the production of massive support frames and structures from 40–80 mm thick Hardox steel, where forces of 1000–1500 tonnes are needed for bending short but ultra-thick profiles.

Producers of steel-bridge structures and hydrotechnical infrastructure (dams, locks, weirs) use the medium G 1500–G 2000 models of the extra-large sheet metal press brake for the production of bridge beams and decks from 30–60 mm thick sheets over lengths of 8000–10000 mm, with the CNC crowning system ensuring angular uniformity over the entire length of the load-bearing parts.

How the WyBend G Series extra-large sheet metal press brake works

1. CNC programming and automatic force calculation — the Cybelec/Delem CNC system calculates the force needed for the programmed material and thickness, verifying that it fits within the selected model's capacity; at forces of 1000–5000 tonnes, the precise calculation prevents overloading the equipment.

2. Large-scale deflection compensation — the CNC crowning system calculates the crowning profile for lengths of 6000–15000 mm; at forces of thousands of tonnes, the deflection without compensation would exceed several centimeters over the 15-meter length — active crowning reduces it to below ±0.01 mm.

3. Back-gauge positioning with large-format extensions — the back gauge with HIWIN extensions positions at the programmed distance with ±0.02 mm even on 10–15 meter long sheets, with the follow-up sheet support assisting the handling of materials weighing hundreds of tonnes.

4. Hydraulic bending at 1000–5000 tonnes — the Parker/Bosch Rexroth hydraulic systems drive the cylinders at the programmed forces with constant pressure over the entire 6000–15000 mm length; the ultra-rigid frame with the reinforcement kit ensures that the machine geometry remains unchanged under extreme loads.

5. Part removal with synchronized support — the follow-up sheet support assists the removal of the finished part; at the extreme dimensions of the parts produced on the WyBend G Series, the removal operation typically involves lifting equipment (cranes, manipulators) integrated into the production flow.

Frequently asked questions about the WyBend G Series extra-large sheet metal press brake

What is the maximum sheet thickness the WyBend G Series press brake can bend?

The maximum processable thickness depends on the chosen model, the sheet material and the bending length. At a force of 5000 tonnes over a length of 15000 mm, the WyBend G 5000 extra-large sheet metal press brake can bend carbon-steel sheets up to 150–200 mm thick on short formats, or 50–80 mm sheets on long 10–15 meter formats. UZINEX provides the exact calculation of the maximum thickness according to the specific material, bending length and desired angle before recommending the model.

What infrastructure requirements (foundation, hall) does the WyBend G Series require?

The WyBend G Series extra-large sheet metal press brake requires special foundations sized for the equipment weight (from a few hundred tonnes for the G 1000 to thousands of tonnes for the G 5000), halls with a clear height of 8–16 meters and lifting systems (overhead cranes) with a capacity of 50–500 tonnes for handling the processed sheets. UZINEX provides complete consulting for the foundation design, the specification of the hall and the lifting systems needed before purchase.

Why classic Parker/Bosch hydraulics instead of the hybrid servo system on the WyBend H Series?

The hybrid hydraulic-servo system of the H Series offers 40–70% energy saving — a significant advantage at forces of 300–800 tonnes. At the 1000–5000 tonne forces of the WyBend G Series extra-large sheet metal press brake, the engineering priority shifts toward maximum reliability and the ability to absorb extreme load peaks — hybrid servo systems at this scale would involve disproportionate cost and complexity. The high-capacity classic Parker/Bosch Rexroth hydraulic system, generously sized for continuous loads of thousands of tonnes, ensures industrial reliability over decades of operation under the severe conditions of the shipbuilding and heavy-construction industries. UZINEX recommends the H series for applications below 800 tonnes where energy saving is a priority, and the G series when the part dimensions require forces above 1000 tonnes.

How long does the delivery and installation of a WyBend G 5000 take?

The G 5000 model of the WyBend G Series extra-large sheet metal press brake has dimensions of 20×10×15 meters and a weight of thousands of tonnes — delivery involves special transport in segments, assembly at the customer's site and metrological calibration over several weeks. The typical lead time from order to commissioning is 6–12 months, depending on the complexity of the infrastructure required at the customer's site (foundation, hall, lifting systems). UZINEX coordinates the entire process — foundation design, special transport, assembly, calibration and operating-team training — with a dedicated project manager throughout the implementation.
