CNC mandrel tube bending is a specialized service that utilizes advanced machinery and computer-controlled processes to precisely bend tubes and pipes with accuracy and consistency. This technique is crucial in industries such as automotive, aerospace, construction, and manufacturing, where the creation of bent tubular components with specific shapes, angles, and dimensions is required.

Process Overview:

CNC mandrel tube bending involves using a mandrel (a solid rod or flexible material placed inside the tube) to maintain the shape and integrity of the tube during the bending process. The general steps include:

  1. Design and Programming: A digital model or Computer-Aided Design (CAD) file is prepared, specifying the desired bends, angles, and dimensions of the tube. This design is then converted into instructions for the CNC mandrel tube bending machine.
  2. Material Preparation: The tube or pipe to be bent is selected based on the material type, diameter, and wall thickness required for the application. It is then cut to the appropriate length for bending.
  3. Bending Process: The tube is loaded into the CNC mandrel tube bending machine, which uses computer-guided precision to clamp, grip, and rotate the tube while a mandrel maintains its shape internally. The machine applies controlled force to bend the tube according to the programmed specifications.
  4. Quality Inspection: After bending, the resulting tube is inspected to ensure it meets the precise angles, dimensions, and tolerances outlined in the design.


Services Offered:

  1. Precision Tube Bending: CNC mandrel tube bending services provide precise and accurate bending of tubes and pipes with complex shapes, multiple bends, and various radii while maintaining structural integrity.
  2. Customization: These services cater to custom designs and specific requirements, offering flexibility in producing unique bent tube components.
  3. Material Versatility: CNC mandrel tube bending can handle various materials, including steel, stainless steel, aluminum, copper, brass, and alloys.
  4. Prototyping and Production: Services accommodate both prototype development and large-scale production runs, delivering consistent quality across batches.


  • Accuracy and Consistency: CNC mandrel tube bending ensures consistent and precise bending, minimizing errors and maintaining dimensional accuracy.
  • Complex Geometries: Capable of producing intricate tube shapes, angles, and configurations that are otherwise challenging to achieve using traditional bending methods.
  • Strength and Integrity: The use of a mandrel during bending minimizes distortion and maintains the structural integrity of the tube.
  • Efficiency and Cost-Effectiveness: CNC automation reduces production times and material waste, making it a cost-effective solution for high-quality bent tube components.

CNC mandrel tube bending services are essential for industries requiring accurately bent tubes and pipes for various applications, offering precise customization, high-quality fabrication, and efficient production capabilities.
