Four Rolls Plate Bending Machine
4R-IHS
Four Rolls Plate Bending Machine
The Four-Roller Mechanical Plate Bending Machine is an industrial machine used for bending metal sheets, performing the bending operation with high precision through a system that involves the coordination of four rollers. The top roller is fixed, while the bottom roller is movable, and the two side rollers ensure the smooth bending of the material. This design allows metal sheets of various thicknesses and widths to be bent to the desired angle and diameter.
Thanks to the effective coordination of the four rollers, the machine is widely preferred in the construction, automotive, machinery manufacturing, and energy sectors. The Four-Roller Mechanical Plate Bending Machine offers superior performance, especially in bending large-diameter and heavy metal sheets, providing high efficiency in production processes and guaranteeing high-quality results.
