Two-rollfour-roll bending machine

This two-roll plate rolling machine delivers outstanding productivity: it completes one-step forming without pre-bending or secondary processing, with daily output of 400–4,000 pieces per unit; high-speed automated variants finish one sheet in merely 20 seconds. It boasts top-tier rolling precision: roundness error stays within ±0.4% of workpiece diameter, with a 0.5mm tolerance and seamless joint free of flat marks, outperforming conventional plate rollers. It eliminates residual flat ends on workpieces, cutting material waste and lifting utilization efficiency, a key upgrade over standard three/four-roll models. Flexible elastic rollers enable scratch-free, wrinkle-free non-destructive rolling, fitting perforated, embossed, mirror and coated sheets. Supporting full CNC automation, it forms unmanned production lines covering sheet separating, loading, rolling and unloading. Compatible with 0.15–8mm thick, max 3000mm wide carbon steel, stainless steel and aluminum sheets. Simple structure, low power consumption, standard-compliant electric control with motor overload protection for eco-friendly, stable operation.

Product Features

1，Exceptionally High Productivity | Formed in a single pass without the need for pre-bending or secondary forming; daily output per machine ranges from 400 to 4,000 pieces. High-speed, fully automated models can process a sheet in as little as 20 seconds.

2， Superior Rolling Precision | Roundness error is ≤±0.4% of the diameter (D), with workpiece roundness maintained within a 0.5mm tolerance. Offers higher precision than other types of Plate rolling machines, with no visible flat spots at the seam.

3， No Flat Ends, Material Savings | Produces a perfect arc without leaving flat ends; eliminates the need for pre-bending, directly boosting material utilization and production efficiency. Overcomes the issue of residual flat ends at the edges inherent in the structural design of traditional three-roll or four-roll machines.

4️， Non-Destructive Processing, Scratch-Free Surface | Features flexible contact between the plate and the elastic roll; prevents wrinkling and surface scratching during the rolling process. Suitable for processing sheets with perforations, embossed patterns, mirror finishes, protective films, or special coatings.

5， High Level of Automation | Can be equipped with CNC systems and hardware to automate the entire workflow—including sheet separation, picking, loading, alignment, feeding, rolling, and unloading—creating a fully automated two-roll plate rolling production line.

6， Broad Compatibility | Handles metal sheets ranging from 0.15mm to 8mm in thickness and up to 3000mm in width, including carbon steel, stainless steel, aluminum, and coated sheets. Capable of processing mirror-finished and coated materials without surface damage.

7， Eco-Friendly and Energy-Efficient | Fully CNC-controlled production with a simple equipment structure and low energy consumption; the electrical control system complies with national standards, and motors feature short-circuit and overheat protection.
