As a process tube bending starts with loading a tube into a pipe bender and clamping it into place between two dies, the clamping block and the forming die. The tube is also loosely held by two other dies, the wiper die and the pressure die.Bends are made by forcing tube against a die to make it change shape. Other methods include pushing a pipe through rollers to force it into a curve.

Some typical industry bending,car parts bending like exhaust mandrel pipe tube bending,car bumper bending, car seat bending,furniture industry(chairs, medical beds) which normally need our 63CNCor 76CNCrigid pipe tube bender machine. Different car parts bending choose different function machine like hydraulic mandrel bender, electric pipe tube bender.Machine reach to max 3D(three dimensional) bending capacity in 3 inch for carbon steel bending and if profile bending which based on real situation. If serpentine bending required can also be customized to max your bending convenience and efficiency.

If you are bending pipes or tubes you need to take note of the following considerations:

  • Size and wall thickness of the work piece

  • Materials to be bent

  • Number of bends in the part

  • Proximity of the bends to one another (distance between bends, if any)

  • Plane of bend relationship to one another

  • Production rates

  • Finished part tolerances (such as for wall thinning and point-to-point dimensions)

  • Centreline radius of the bends

  • Initial cost of equipment (plus training, service, support, repair parts, and tooling)

  • Return on investment

Basic tools used in pipe bending are:

  • Bend die – tube bent over to create angle

  • Clamp die – holds other side of bend die in place

  • Pressure die – holds tube on top of bend

  • Wiper die – holds tube under bend

When a pipe is bent the outside wall becomes thinner due to stretching, and compression of the inside wall causes it to become thicker.

Four main factors are involved in bending tube:

  • Material – wall thickness

  • Machine

  • Tooling

  • Lubrication needed
