Roller leveler – Serving the aluminum sheet processing industry

Our industrial-grade multi-roll precision leveling machine is engineered to systematically eliminate material imperfections such as ripples, warping, and coil breaks in both sheet and coil metal. Through its precision-engineered roll array, it applies controlled bending and stress-relieving actions, resulting in superior material flatness and dimensional stability. By integrating this machine into your production line, you directly enhance the quality of your final rolled products while boosting overall throughput and reducing scrap rates.

Roller leveler : bringing perfect flatness to your aluminum sheet

In the metal manufacturing process, achieving perfect flatness is a universal challenge. Whether processing hot-rolled or cold-rolled steel, aluminum coils, or other non-ferrous metals, inherent material stresses invariably manifest as surface and shape defects. Common issues such as ripples, sickle bending (camber), and warping are not merely cosmetic; they directly compromise the quality of the final product and severely hinder efficiency in downstream processes like stamping, coating, or assembly. Our advanced multi-roll leveling machine is engineered with a singular focus: to precisely and consistently eliminate these pervasive flatness issues at their root.

Main advantages and characteristics of roller leveler：

Unmatched Leveling Precision: Our machine features a uniquely engineered arrangement of work rolls and support rolls. This high-density configuration ensures uniform and controlled plastic deformation across the entire sheet surface, effectively eliminating stress gradients to guarantee exceptional, consistent flatness that meets the most stringent tolerances.
Exceptional Versatility & Flexibility: The machine is designed for ease of adjustment, enabling quick adaptation to a wide spectrum of materials—from steel and stainless steel to aluminum and copper—across various thickness ranges. This allows for rapid changeover between product batches, significantly minimizing downtime and maximizing production line flexibility.
Intelligent CNC Control System: An intuitive robotized CNC interface allows operators to set and adjust parameters with ease. The system intelligently automates critical settings, automatically calculating and applying the optimal roll gap and pressure. This advanced automation eliminates variability from human factors, ensuring repeatable, high-quality results batch after batch.
Enhanced Strength & Long-Term Durability: Built for relentless performance, all key components—including the rollers and the robust frame—are manufactured from high-quality alloy steel. These critical parts undergo rigorous heat treatment processes to maximize resistance to wear and plastic deformation, even under the most demanding cyclic loading conditions, ensuring extended service life and reliability.
Energy Efficiency & Low Operating Costs: An adjustable-speed drive system, combined with an optimized mechanical structure, works in concert to reduce overall energy consumption. Furthermore, a simplified and accessible design streamlines routine maintenance and serviceability, directly contributing to lower ongoing operational costs.

Problem solved:

Addressing Longitudinal and Transverse Waviness: We eliminate both directional ripples by applying precise, controlled pressure across the entire sheet surface, ensuring uniform material flow and perfect flatness.
Rectifying Camber and Bow: Our machine systematically corrects any linear deviation (camber) or cross-directional arc (bow) in the sheet, guaranteeing straight edges and a geometrically true shape.
Relieving Internal Locked-in Stresses: The leveling process effectively neutralizes residual stresses induced by prior cutting, rolling, or slitting operations. This stabilizes the material, preventing subsequent distortion and ensuring dimensional stability in your final product.
Enabling Superior Surface Finishing: By delivering an impeccably flat and stress-free substrate, our machine prepares the metal surface for demanding downstream processes. This is essential for achieving flawless results in high-quality painting, mirror polishing, or the uniform application of functional coatings.
