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 cylinder as a hydraulic 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 coiling 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 parts and wiring materials in industries such as automotive and air conditioning. Bending machines are mainly used for plastic forming of pipes.
