Founded in 1958 as China's first state-designated heavy machinery enterprise, EZHONG has specialized in plate bending, leveling, hydraulic presses, and profile bending equipment for over 60 years. In the 1980s, we invented China's first fully hydraulic VCD 3-roll plate bender, breaking the foreign monopoly. Today, we serve 70%+ of China's top pressure vessel makers and export to 30+ countries across 5 continents.

From wind energy to nuclear power, EZHONG's precision leveling and forming solutions optimize manufacturing for 10+ global industries. Achieve ±0.5mm accuracy, eliminate rework, and unlock new market opportunities.
From inventing China's first fully hydraulic VCD 3-roll plate bending machine to building the world's largest 8000T bender — EZHONG has set every major milestone in China's heavy plate forming industry. Our technology serves 70%+ of China's top pressure vessel manufacturers and powers critical infrastructure across 30+ countries.
360mm × 3200mm cold rolling — the largest single 3-roll plate bending machine ever built. Only EZHONG manufactures at this scale.
Serving 70%+ of China's large pressure vessel manufacturers by value. Dominant in chemical, boiler, and pressure equipment.
21 patented technologies. Joint lab with Huazhong Univ. & Wuhan Univ. of Technology. Two national invention patents for armor steel.
Originally a state-designated backbone factory under the First Ministry of Machinery Industry. Nearly 70 years of continuous innovation.
Setting industry records for capacity, thickness, strength, and temperature since 1958. EZHONG machines operate at the extreme edge of plate forming — from cold-rolling 360mm reactor shells to hot-leveling armor steel at 1000°C. These numbers represent real machines operating in real factories worldwide.
"EZHONG's 3-roll plate bending machine transformed our wind tower production line. Tapered shell rolling achieves ±0.1° precision, and our production cycle reduced by 40%. The RMB 41 million contract was one of our best capital equipment investments."
Results: ±0.1° precision · 40% faster production · RMB 41M contract
"The EZW43CY is the ONLY machine in China capable of leveling 1100 MPa armored steel. ±0.05mm flatness exceeds MIL-DTL-46100 standard by 37%. EZHONG's two national invention patents for armor steel leveling make them our exclusive supplier for this critical application."
Results: ±0.05mm flatness · 37% above MIL standard · 2 national patents
"Achieved ±2mm/m flatness required for robotic welding of excavator arms and crane booms. Welding interruption rate dropped from 30% to 2%. EZHONG's EZW43 high-strength steel leveler operates 24/7 in our production line."
Results: ±2mm/m flatness · 30%→2% weld errors · 24/7 operation
