Bend machines can be broadly 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 for pipeline laying 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 jack, offering the advantages of lower cost and ease of use compared to CNC bending equipment, and dominating the domestic bending machine market. CNC bending 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 used for bending various pipe fittings and wires in industries such as automotive and air conditioning. Bending machines are mainly used for plastic forming of pipes.
