Why Choose HOGI 2-Roller Rolling Technology
One-Pass Forming Without Pre-Bending: Unlike traditional 3-roller machines that require pre-bending of leading/trailing edges, our 2-roller design forms the complete cylinder in a single pass — saving 40-60% production time with no straight-edge waste.
Superior Roundness & No Surface Damage: The elastic lower roller conforms to the plate surface, distributing pressure evenly. This eliminates flat spots at seams and prevents scratches on mirror finish, plated, or coated materials — ideal for decorative and precision components.
Touch Screen Automation: One-key operation with PLC touch screen interface. No skilled operator required — input diameter and thickness, and the machine automatically adjusts pressure and roller speed for consistent results every time.
Wide Material & Diameter Range: Process carbon steel (diameter 150-1500mm), stainless steel (diameter 150-1000mm), aluminum, copper, and galvanized sheet. Available in 6 standard models with custom configurations.
Versatile Industry Applications: Perfect for ventilation pipes, smoke pipes, solar water heaters, pressure vessels, gas cylinders, silencers, automotive fuel tanks, food machinery, fire equipment, and household appliances.

HOGI Hydraulic 2-Roller Plate Rolling Machine Manufacturer — This specification page covers technical parameters of our HG series 2-roller rolling machines, including standard and heavy-duty configurations, material capacity, and rolling diameter ranges for cylinder forming applications.
Working Principle
The upper roller is a rigid steel roller. The lower roller consists of a steel core with an outer elastic layer (polyurethane compound). When the metal plate is placed between the two rollers and hydraulic pressure is applied, the elastic lower roller deforms into a concave shape, wrapping the plate around the upper roller. As both rollers rotate simultaneously, the plate is continuously bent and formed into a precise cylinder in a single pass — eliminating the need for pre-bending.

Technical Principles — Elastic Roller Deformation Technology
The key differentiator of 2-roller technology is the elastic lower roller. Made from high-durability polyurethane compound bonded to a steel core, the elastic layer deforms under hydraulic pressure to match the plate thickness. This creates a uniform bending force distribution along the entire contact length, eliminating flat spots at plate edges and preventing surface marks on decorative materials. Unlike 3-roller machines that require multiple passes and pre-bending, the 2-roller design completes the full 360° cylinder in one continuous rotation.
Technical Highlights
1. One-Pass Forming Efficiency: The 2-roller design eliminates pre-bending and progressive rolling passes. Cylinders are completed in a single rotation cycle — reducing cycle time by 40-60% compared to traditional 3-roller machines. No straight-edge waste means 100% material utilization.
2. Elastic Layer Pressure Distribution: The polyurethane elastic layer conforms to plate thickness variations and surface irregularities. This ensures uniform bending force across the full width, delivering consistent roundness without flat spots at the leading/trailing edges.
3. PLC Touch Screen Automation: Siemens or Delta PLC control with HMI touch interface. One-key operation — input target diameter and material thickness, and the system automatically calculates optimal hydraulic pressure and roller rotation speed for repeatable results.
4. Surface Protection Technology: The elastic lower roller exerts no localized high-pressure points, eliminating scratches, dents, and roller marks on mirror finish, plated, coated, and polished materials — critical for decorative and high-end applications.
