Electro-hydraulic sheet bending press LAZIRON combines the efficiency of electric servo control with the power of the hydraulic system, delivering the best force-to-accuracy ratio for workshops that bend thick sheet metal constantly. Proportional servo valves replace conventional valves, eliminating delays and position losses.
With bending force between 100 and 600 tonnes, usable length 2500-6000 mm and a hybrid servo-hydraulic system, every LAZIRON HPB electro-hydraulic sheet bending press is dedicated to workshops producing on heavy plate: shipyards, machinery factories, structural steel for construction and industrial tank manufacturers.
What makes the LAZIRON HPB an electro-hydraulic sheet bending press built for real production
The LAZIRON HPB electro-hydraulic sheet bending press concentrates in a single system the advantages that matter on the production line: repeatable accuracy, parameter automation, predictable operating costs and long service life for critical components.
• Hybrid servo-electric + hydraulic system, proportional valves controlled by servo motor eliminate the delays and position losses typical of conventional hydraulic systems.
• Force of 100-600 tonnes over lengths of 2500-6000 mm, covers the entire range of heavy industrial applications, from machinery panels to shipyard structural elements.
• Positioning accuracy of ±0.02 mm, comparable to purely electric presses, but at a force capacity 3-4 times higher, unique on the market at the LAZIRON price.
• Energy consumption reduced by 35-45%, vs conventional hydraulic presses with a constant pump, thanks to proportional pumping on demand only.
• Automatic hydraulic crowning compensation, adjusts the table curvature under pressure in real time, maintaining parallelism over long lengths above 4 metres.
• CNC control with 6-8 NC axes, Y1, Y2, X, R, plus Z1, Z2 for side stops and V for automatic die angle adjustment.
• Pilz or Lazer Safe laser safety system, with a 3D proximity zone that allows ergonomic operation without physical barriers, EN 12622 compliance.

Industries that use a LAZIRON electro-hydraulic sheet bending press
A LAZIRON electro-hydraulic sheet bending press is chosen by workshops with heavy production: shipyards, machinery factories (excavators, cranes, mining equipment), industrial tank manufacturers and structures for civil construction.
The shipbuilding industry uses a single LAZIRON HPB electro-hydraulic sheet bending press of 500-600 tonnes × 6000 mm to bend 20-25 mm hull plates for large vessels, eliminating the need for multi-pass hydraulic pressing and ensuring exact geometry on the first attempt.
Storage tank factories (pressure vessels, fuel tankers, industrial silos) bend 12-30 mm structural plates for cylindrical and conical elements. Heavy machinery manufacturers (chassis components, pivoting joints, crane arms), structures for steel bridges and factories making wind turbine components recoup the investment in the electro-hydraulic sheet bending press within 24-36 months.
Materials compatible with a LAZIRON electro-hydraulic sheet bending press
With force configurable between 100 and 600 tonnes, every LAZIRON HPB electro-hydraulic sheet bending press covers the heavy industrial range of sheet metal, up to thicknesses that exceed the capacity of purely electric systems.
The automatic hydraulic crowning compensation system is essential for long parts above 4 metres, where deflection of the table under pressure would affect bending quality.
Typical performance per material
• Carbon steel, max. thickness (with 600 t × 6000 mm): 25 mm
• Stainless steel 304/316: 20 mm
• Low-alloy steel S355/S420: 22 mm
• Structural marine aluminium: 30 mm
How the LAZIRON HPB model works
The workflow of a LAZIRON HPB electro-hydraulic sheet bending press combines the speed of the servo system with the industrial force of the hydraulics, optimised for heavy parts.
1. The operator loads the program into the DA-66T or Esa S840 control directly from DXF or a parts library.
2. The system automatically calculates crowning compensation according to the applied force and the part length.
3. The back gauge positions itself on the Y1, Y2, X coordinates, plus Z1/Z2 for side stops.
4. The operator places the sheet on the die with a crane, supported on the self-positioned stops.
5. The Pilz laser safety system checks the zone and allows the cycle to start with controlled approach-work-retraction speeds.
6. At the end, crowning compensation is adjusted for the next program, with no human intervention.
For integration with other equipment in your workshop, the machine connects natively to the other LAZIRON equipment through a shared MES.
Frequently asked questions about the electro-hydraulic sheet bending press
What is the difference between the LAZIRON HPB electro-hydraulic sheet bending press and a conventional TPBS hydraulic press?
The HPB uses a servo motor to control the proportional valves (accuracy ±0.02 mm, consumption -35%). The TPBS uses conventional hydraulic valves with a mechanical torsion bar for synchronisation (accuracy ±0.05 mm, standard consumption, but a price 25-35% lower). For workshops producing on stainless steel and demanding parts, the HPB is optimal. For bending on commercial steel with wide tolerances, the TPBS offers a better cost-performance ratio.
Can I use the LAZIRON HPB electro-hydraulic sheet bending press for lengths over 6 metres?
Standard configurations go up to 6000 mm. For lengths of 7000-10000 mm, LAZIRON offers the HPB-XL configuration with a reinforced body and two synchronised rams. These configurations are made to order, with a delivery time of 12-16 weeks vs 6-8 weeks for the standard.
What installed power does a 320-tonne × 4000 mm press require?
Approximately 30-40 kVA for the complete servo-hydraulic system, plus 5-8 kVA for the auxiliary systems (control, lighting, ventilation). Typical total of 35-48 kVA at peak demand, but the actual average consumption over an 8-hour shift is only 8-12 kVA thanks to proportional pumping during the effective pressing phases only.
What maintenance does the hydraulic system require?
Hydraulic oil changed at 4000 hours (annually when operating 2 shifts) or every 2 years, whichever comes first. HYDAC filters changed at 2000 hours. Parker seals inspected every 6 months. Overall, the annual maintenance cost is 50-60% lower than for a conventional hydraulic press thanks to the reduced pump cycles.
What space and foundation conditions do I need?
For a 500-tonne × 5000 mm press: a hall of 9 × 8 m (press + crane space + sheet storage area), clear height of 5.5 m, reinforced concrete foundation 400-500 mm thick (with static calculation for the press weight of 25-35 tonnes). Three-phase voltage of 380 V, absorbed power variable according to tonnage.
ROI calculation for a LAZIRON electro-hydraulic sheet bending press
The decision to invest in an electro-hydraulic sheet bending press is not made on the basis of technical specifications alone, what matters is how the equipment translates into real monthly cash-flow figures for your workshop.
For workshops currently subcontracting the equivalent operations at 2026 market prices, bringing them in-house with a LAZIRON electro-hydraulic sheet bending press reduces the effective cost per operation by 50-70%. At a typical monthly volume operated in-house instead of subcontracted, the investment is recovered in 18-30 months under current market conditions.
The additional margin comes from three directions: savings versus subcontracting, offering services to local external clients at market prices, and reducing delivery times to end clients by 40-60%, which allows premium pricing on urgent orders or those with short deadlines.
