We develop and manufacture complete production-line equipment for lightweight, high-strength tubular chassis components. Each production line integrates tube bending equipment, tube hydroforming presses, and laser cutting systems, with core equipment designed and built in-house. Direct control over equipment design, process flow, and tooling ensures alignment with the actual production requirements of automotive tubular chassis components.

      Angle: 13-axis full-servo bending ensures accurate control at any bending angle, with angular accuracy within 0.05° and feeding accuracy up to 0.05 mm.
      Circularity: Multi-core mandrel bending combined with synchronized lubrication helps maintain stable tube roundness during the bending process.
      Thinning: Wall thinning is managed by coordinating the bending motion with auxiliary pushing and mandrel movement. Push-feed compensation and synchronized lubrication help keep wall thickness more consistent and improve forming stability.

To determine the bending speed, it's necessary to consider the tube diameter, material, hardness, and wall thickness. Softer or thin-walled tubes are normally bent at a slower speed, so the tube does not lose its shape during bending. Heavy or harder tubes are more stable and can be bent more quickly without losing their shape. In most cases, the number of axes on a tube bending machine is determined by the complexity of the tubes that need to be processed. For small-diameter tubes with simple bends, 3- or 4-axis machines are usually enough. If the tube diameter is larger or if the bending geometry is complex, such as side or inclined bends, 5-axis bending machines or higher configurations usually provide better control and help maintain both shape and strength.

Planning an automated tube processing line starts with understanding the tube material, part geometry, and production volume. When planning a tube processing line, it is important to consider the process flow, equipment compatibility, automation level, and quality control. A good tube processing line has a suitable balance between flexibility and efficiency, focusing on what is actually needed for tube production instead of adding complexity that does not add real value.
