Bending machines can be roughly 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 pipeline installation and repair, featuring multiple functions, reasonable structure, simple operation, easy mobility, and quick installation. This machine, in addition to bending capabilities, can also use the hydraulic cylinder as a hydraulic jack, offering the advantages of lower cost and ease of use compared to CNC bending equipment, thus dominating the domestic bending machine market. CNC bending machines can perform helical bending on pipes at room temperature, either a single bend radius (single mold) or two bend radii (double mold), and are widely used in the bending of various pipe fittings and wires in industries such as automotive and air conditioning. Bending machines are mainly used for the plastic deformation of pipes.
