RBD-4HD - RBD-4HL Plate Rolls
The KAAST series of 4-roll plate rolls bending machines RBD-4HD and RBD-HL roll sheet metal into shapes such as cylinders and cones for wind-power, HVAC ducts, construction, shipbuilding, tanks, trucks, and more. The upper roller is fixed in place, the lower roller moves upwards and downwards to clamp onto the workpiece, and the side rollers move up and down at an oblique angle to adjust the shape of the roll. Model RBD-4HD features motorized top and side rollers, and our RBD-4H and HL features a motorized top roller and a motorized bottom roller.
Our bending machines uses top brand components like Siemens, Rexroth, Bosch, Parker, Atos, Telemechanique, SKF, NSK, and FAG to guarantee high-quality lifelong performance. The rollers have solid, welded frames and high-quality, heavy-duty bearings, which minimize friction and ensure even rotation of the rollers. Because the planetary gears are mounted directly on the rollers, the transmission of force takes place without loss of force or power. Simultaneous use of torsion bars and hydraulic units ensures accuracy and enables flexibility. With over 50 years of experience in sheet metal bending and thousands of reference customers, KAAST assures first-class support in any application or maintenance question.
