Hydrofold presses mfg co has developed hydraulically operated and plc controlled multiform machine. It has four adjustable forming modules which give 4 bends in one loading of sheet. The machine can be operated in manual or auto mode. In auto mode, the central clamp beams and end clamp beams clamp the sheet first. The end forming beams then fold two end bends and get retracted. The end clamping beams then get retracted. The central forming beams then form remaining two bends and retracted. The central clamp beams then lift making it possible to withdraw the formed panel. The entire sheet is supported properly during complete bend cycle and absolutely no handling is required. The machine is ideally suited to manufacture evaporator bodies of refrigerators, cabinets of air-conditioners, washing machines and panels. Essential features are: high production: cycle time for 4 bends is only 12 to 14 seconds; flexibility to accommodate different sizes as bend distances are adjustable; minimum setting time; high repetitive accuracy; minimum maintenance; pre-coated sheet can be bent without damaging the sheet; extensive safety features like two pushbutton start, emergency stop and photoguard.
