Bend machines can be broadly categorized into CNC bend machines, hydraulic bend machines, and so on. The applications of bend machines: Hydraulic bend machines are mainly used in electrical construction, highway and railway construction, boiler, bridge, ship, furniture, decoration, and other pipeline installation and repair. They have many functions, reasonable structure, simple operation, easy mobility, and quick installation. This machine, in addition to bending pipes, can also use the hydraulic cylinder as a hydraulic jack, offering the advantages of being more affordable and user-friendly compared to CNC bend machines. It holds a leading position in the domestic bend machine market. CNC bend machines can perform helical bending on pipes at room temperature, either a single bend radius (single model) or two bend radii (double model), and are widely used in the bending of various pipe fittings and wires in industries such as automotive and air conditioning. Bend machines are mainly used for plastic forming of pipes.
