Bend machines can generally be categorized into CNC bending machines and hydraulic bending machines, etc. The applications of bending machines include: hydraulic bending machines are mainly used in electrical construction, highway and railway construction, boiler, bridge, ship, furniture, decoration, and other aspects for pipeline laying and repair. They have the advantages of multiple functions, reasonable structure, simple operation, easy mobility, and quick installation. This machine, in addition to bending function, can also use the hydraulic cylinder as a hydraulic jack, offering the features of lower price 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 bending radius (single mode) or two bending radii (double mode), and are widely used in the bending of various pipe parts and wires in the automotive, air conditioning, and other industries. Bending machines are mainly used for the plastic forming of pipes.
