1. Hydraulic driven with large pressure, speed uniformity and low noise. 2. Apply to one piece or several pieces metal wires bending, high efficiency and good forming. 3. Apply to single angle bending or continuous automatic bending for polygonal frame through PLC controlled. 4. Quadrilateral length can adjust to any length for bending within machine width. 5. Special design the mold size and control the stroke of bending cylinder to obtain different bending angle. 6. Widely used for wire frame ,angle bending and forming of metal material, such as iron wire(plate), steel wire(plate),aluminum wire(plate),copper wire (plate),etc.
