EZHONG manufactures a comprehensive range of plate bending machines designed for medium and thick plate forming applications. Our machines deliver precision rolling performance across diverse industrial sectors including pressure vessels, shipbuilding, wind energy, and heavy fabrication.
Our product lineup includes 3-roll plate bending machines, 4-roll plate bending machines, specialized wind tower plate rollers, ship plate bending equipment, and custom solutions for demanding applications. Each series is engineered for specific production requirements and material specifications.
With decades of experience in heavy plate forming technology, EZHONG combines hydraulic precision, CNC control systems, and intelligent algorithms to deliver reliable, high-performance plate bending solutions that meet the most demanding production standards.
If you operate pressure vessel manufacturing facilities, shipyards, wind tower production plants, heavy steel fabrication workshops, or engineering construction companies—and you require reliable, precise plate forming equipment for cylindrical vessels, conical shells, curved structural components, or large-diameter pipes. EZHONG provides fully customized plate bending solutions matching your material specifications, plate dimensions, rolling capacity requirements, and automation levels. From compact 3-roll systems to advanced 4-roll precision machines, we deliver complete forming solutions for all heavy plate rolling applications.
Select the series that matches your production requirements — from general hydraulic CNC to specialized wind tower and marine configurations
Choose between our 3-roll and 4-roll plate bending machine series based on your thickness requirements and precision needs

| Max Capacity | 8000 tons (world's largest) | Up to 200mm thickness |
| Best For | Heavy plates (≥20mm), large-diameter coils, wind towers, marine | Medium plates (6–200mm), precision work, export markets |
| Primary Applications | Pressure vessels, wind towers, shipbuilding, large pipes | HVAC, wind towers,automotive, precision vessels, sheet metal |
In the 1980s, EZHONG invented China's first fully hydraulic VCD 3-roll plate bending machine, breaking foreign technology monopolies. VCD allows independent adjustment of the upper roller in both horizontal and vertical directions.
Servo-proportional directional control valves with closed-loop feedback ensure both upper and lower rollers stay within ±0.1mm of target position, delivering coils with ±0.5mm roundness—export-grade quality every piece.
The EZW11S-360×3200 represents the world's largest single 3-roll plate bending machine with 8000-ton max force and 360mm plate thickness capacity. Only EZHONG manufactures at this scale.
All 4-roll machines ship CE-certified standard. Ready for European, North American, and Asian markets without customs delays or re-testing.
Rolling 30–120mm thick tapered tower sections at 20–30 min/piece.
EZHONG serves 70%+ of China's top pressure vessel makers.
Rolling 60–200mm ship hull plates up to 21m length.
Spiral ducts, round pipe, flexible connectors for commercial systems.
Exhaust components, bumper cores, structural rings for cars & motorcycles.
Rolling 50–200mm thick pipe walls for offshore and high-pressure applications.
3-roll machines are ideal for thick plates (≥20mm) and large-diameter coils. 4-roll machines are ideal for medium plates (6–50mm) and precision work. For plates ≥20mm, 3-roll is recommended. For plates 6–50mm with tight tolerance requirements, choose 4-roll for 40% faster cycle time and ±0.5mm roundness.
Variable center distance (VCD) means the upper roller can move independently in both horizontal and vertical directions, rather than being fixed. This enables 40% better pre-bending, tighter minimum rolling diameters, and 30% foundation cost savings.
360mm for the EZW11S-360×3200 model — the world's maximum for a 3-roll bending machine. For 4-roll machines, maximum thickness is 100mm.
Yes, CNC is standard on EZW12X (4-roll) and available on both 3-roll and 4-roll machines as upgrade. Includes user-programmable coil profiles, real-time diameter feedback, preset recipes, and remote diagnostics.
Standard 3-roll models: 4–6 months. Standard 4-roll: 3–5 months. Wind tower specialized: 5–7 months. Marine models: 6–8 months. Custom configurations: 4–6 months.
Yes, including on-site installation, commissioning, and 3–5 day operator training for all machines.
