Plate Roll Bending Machine - HR-4 Series

Our HR-4 Series 4-roll bending machines are engineered with robust frames made from high-quality steel construction and feature fully hydraulic operation. Both the top and bottom rolls are powered by hydraulic motors and planetary gearboxes, ensuring powerful and precise performance. These machines are ideal for shops requiring an easy-to-operate 4-roll design capable of handling materials ranging from 2mm to 50m in thickness. The HR-4 Series machines come standard with conical bending capabilities for creating cone-shaped parts, along with hydraulic adjustments for the bottom and side rolls. Available in lengths ranging from 1m to 8m, these machines offer exceptional flexibility for a wide variety of applications. This ensures you get the perfect solution for your specific needs—rather than a one-size-fits-all approach. plate bending rolls
