The installation of our precision leveling machine at a major metal fabrication company in South Korea marks a significant milestone in delivering advanced sheet‑metal leveling, flatness correction, and industrial automation solutions to global manufacturers. As production standards continue to rise across the metalworking industry, the demand for reliable, high‑accuracy leveling equipment has grown rapidly. This successful installation demonstrates not only the technical strength of our equipment but also the deep trust our international customers place in our engineering capabilities, long‑term service commitment, and proven results in real manufacturing environments.
A Customer Case That Reflects Real Sheet‑Metal Leveling Challenges
The Korean customer is a long‑established supplier in metal processing, sheet‑metal fabrication, laser cutting, CNC machining, and automated production systems. Their products are widely used in industries such as industrial machinery, electronics enclosures, automotive components, and precision assemblies. As their production volume increased, they began facing persistent challenges with sheet‑metal flatness, internal stress, and deformation—issues that directly affected downstream processes such as welding, bending, machining, and surface finishing.
Laser‑cut parts, in particular, often exhibited slight warping or internal stress due to thermal cutting. These defects caused assembly misalignment, welding gaps, and dimensional inconsistencies. Traditional flattening methods were no longer sufficient, and manual correction was time‑consuming, inconsistent, and unsuitable for high‑precision production.
After evaluating multiple coil & sheet leveling solutions, the customer selected our precision leveling machine for its proven accuracy, robust mechanical structure, and advanced automation. Their decision was driven by real production needs—and reinforced by our reliable technical support and previous successful cooperation.
Technical Specifications Designed for High‑Precision Metal Processing
The installed machine is engineered for demanding industrial environments and supports a wide range of sheet‑metal applications. Its technical specifications are optimized for precision, stability, and long‑term reliability:
Working thickness range: 1–10 mm
Maximum working width: 800 mm
Flatness accuracy: up to 0.05 mm
Roller configuration: 19 leveling rollers
Roller diameter: 80 mm
Drive system: dual‑motor drive for stable torque output
Pressure system: hydraulic pressure control for consistent leveling force
High‑rigidity frame ensuring stability under continuous operation
Advanced roller leveling technology for stress‑relief and deformation correction
Automated control system for consistent, repeatable leveling results
These specifications make the machine ideal for laser‑cut parts, stainless steel components, cold‑rolled sheet, aluminum plate, and other precision‑critical applications. The combination of 19 rollers and 80 mm roller diameter ensures optimal contact, pressure distribution, and deformation correction across the entire sheet‑metal surface.
How Roller Leveling Technology Improves Sheet‑Metal Quality
The core of the machine’s performance lies in its advanced roller leveling technology, which uses controlled bending and counter‑bending to eliminate internal stress and correct deformation. As sheet‑metal passes through the 19 rollers, the material undergoes multiple micro‑bending cycles that redistribute internal stress and achieve uniform flatness.
Key benefits of roller leveling include:
Stress‑relief processing that prevents deformation during bending and welding
Flatness correction that ensures dimensional accuracy for precision assemblies
Improved surface quality for downstream finishing processes
Higher consistency compared to manual flattening or traditional press leveling
Better compatibility with automated production lines
This technology is especially effective for laser‑cut parts, which often suffer from thermal distortion. By applying controlled pressure through the hydraulic system and dual‑motor drive, the machine ensures stable leveling force and repeatable results.
On‑Site Commissioning: Immediate Improvements in Production Quality
During installation and commissioning, our engineering team worked closely with the customer’s production managers to optimize leveling parameters for different materials and thicknesses. The results were immediate and measurable:
Significant improvement in sheet‑metal flatness accuracy
Effective stress‑relief, reducing deformation during bending and welding
Lower rework and scrap rates for laser‑cut parts
Higher production efficiency due to stable, predictable leveling performance
Better dimensional consistency for automated assembly lines
Improved welding quality due to reduced gaps and misalignment
Enhanced bending accuracy thanks to uniform material thickness and flatness
The ability to achieve 0.05 mm flatness accuracy brought noticeable improvements to the customer’s quality control and downstream workflow stability.
