3D pipe processing is a technology for manufacturing pipe components with complex spatial shapes. It enables high-precision bending in multiple directions, twisting, branching, drilling, and more, and through integration with CAD/CAM systems, it provides a consistent process from design to manufacturing. Typical processing methods include cutting and opening using 3D laser processing machines, and bending using NC-controlled pipe benders. High-quality bending using mandrels is also possible. It contributes to weight reduction, space saving, and improved functionality in a wide range of industrial fields, such as automotive exhaust system components, hydraulic piping for construction machinery, complex piping for plants, and aircraft components. It is a highly specialized processing field that requires advanced technology and equipment.
