Bend machines can generally be categorized into CNC bending machines and hydraulic bending machines, etc. The applications of bending machines: Hydraulic bending machines are mainly used in electrical construction, public and railway construction, boiler, bridge, ship, furniture, decoration, and other aspects of pipeline installation and repair. They have many functions, reasonable structure, simple operation, easy movement, and fast installation. This machine, in addition to bending functions, can also use the cylinder as a hydraulic jack, which is more cost-effective and convenient to use compared to CNC bending equipment, and dominates the domestic bending machine market. CNC bending machines can perform coiling bending on pipes at room temperature, with either a single bending radius (single mold) or two bending radii (double mold), and are widely used in the bending of various pipe fittings and wires in industries such as automobiles and air conditioners. Bending machines are mainly used for the plastic deformation of pipes.
