3 Rolls for quick economical rolling

With KAAST 3-Roll plate bending machines, RBD-3M and RBD-3HL, cylinders of varying radii can be created easily. Our 3 roll machines feature a locked top roll and either mechanically or hydraulically controlled side rolls, with the hydraulic models including DROs as well. Our bending machines uses top brand components like Siemens, Rexroth, Bosch, Parker, Atos, Telemechanique, SKF, NSK, and FAG to guarantee high-quality lifelong performance.

These plate rolls feature heavy, welded construction, with all rolls mated to high-quality, heavy-duty bearings, which ensures minimum friction and even rotation of the bending rollers and are suitable for forming aluminum or stainless steel. The machines are equipped with drop-end for easy removal of finished parts. Via simple operation with a mobile control panel, these machines are frequently used in the HVAC, aerospace, and tank and vessel making industries

4 Rolls for increased flexibility and faster pre-bending

RBD-4HD - RBD-4HL

The KAAST series of 4-roll plate 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. Our 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. Our 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. The 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.
