Tube End Forming Machine Ultimate FAQ Guide


End-forming techniques modify the geometry of tubes. Tubes are reduced, machined, and shaped into different configurations. They are reshaped so that features like seals, rings, and nut fittings are fixed to connect the tubing to critical components i.e. braking system.

In this quick guide, you’ll learn the basics of operations and recommendations regarding the working/applications of end-forming machines.

Chapter 1. What is end forming?

End-forming is a process used to alter and improve the geometry of a tube. Usually, the transformation occurs near or at the end of the material. This traditional process was once performed using special castings.
But manufacturers now prefer custom, machine-forming for better quality and cost-efficiency.
End forming can be done by beading, expanding, flaring, grooving, reducing, knurling, and flanging the tube. This operation also entails a diversity of part arrangements and components i.e. steel, copper, aluminum, brass, and stainless steel.

Chapter 2. What is an end forming machine?

End-forming is a proper and efficient technique for tube fabrication. But if done by an old process i.e. using castings, it can be time and asset-consuming.

Premium end formers or end forming machines can be used for prompt yet more accurate results. The tubes transformed by using tube end forming machines can be round, rectangular, or square in shape.

By using end-forming machines you can also generate contact points between two different media normally used in automobiles and offers leak-proof services.

Chapter 3. How many types of tube end forming machines are there?

The tube-end formation process for changing the shape of the end of a tube is carried out by some basic methods:

  • Segmented tool sizing
  • Ram forming
  • Rotary forming
  • Roll forming
  • Spinning 

The most common ones are segmented tool sizing and ram forming. 

Rotary forming, roll forming, and spinning have their particular benefits, as they are capable of functioning around the circumference of the metal tube. Particularly, they are used for progressive tube-forming processes i.e. sharp angles and essential diameter alterations.

Segmented tool sizing, ram forming is used to work the entire circumference at one time.

Chapter 4. What is the working principle of a tube end former?

Tube end forming processes depend mainly upon the deformation of ends of the tube. The deformation is followed by desired shape production rather than adding caps or welding. A tube end fabrication by using a tube end forming machine is quite clear-cut and simple: 

  • You can insert a hollow tube into any tube end forming machine, using a manual or automatic loading method.
  • Fix the tube in position and secure it with clamp dies.
  • Then the end forming starts working; it uses some sort of pressure i.e. hydraulic pressure.
  • The hydraulic cylinder hit and pushes punches towards the tube.
  • It presses the ends of the tube against a forming tool to form the desired shape on the tube end
  • The method and machine type used depends upon the material thickness, shape required, and tolerances.

Chapter 9. What shapes can tube end-forming machines make?

Tube-end forming machines are designed to transform tubes into different configurations. The tubes are altered by a premium tube end former, and they can be round, rectangular, or square in shape. Usually, some of the most common shapes can be molded by:

  • Reduction(swaging): reduction is used to lessen the outside diameter (OD) of any tube so that different parts can fit into each other.
  • Expand: You can enhance the overall exterior diameter (OD) of a tube by expanding technique.
  • Bead (or bulge): It is used to form a bead on the tube end and so that the hose can easily move over a tube.
  • Flare: It enables the connection of tubes or other assemblies together.
  • Nose: The technique is used exclusively to restrain the movement of a gas or fluid out of the tube’s end.
  • Groove: Seal a part of O-rings into an assembly by grooving.
  • Notch: Notching allows you to weld a part onto another tube.
  • Flat: By flattening a tube’s end, you can combine it with other parts by piercing a hole in the flattened surface.

Chapter 10. How to perform beading for efficient tube fabrication?

Beaded tubes can be created by using a combination of hand beading tools or, end-forming machine beading rolls. The diameter and thickness of the tube walls determine the method used for its production. 

A beaded mount is added to the tube forming machines to generate bead-shaped tubes. For gaining efficient results the bead frame should also include proper rollers. 

Lubricate the exterior as well as the interior of the tubes. You can use a light oil to reduce friction between rollers. By doing so you can also prevent different tube damage i.e. scratches. 

The marks present on the sixteenth inch on the rollers designate the exterior diameter of the tubing. This is the diameter that can be beaded by using the rollers.

  • It is also used to link exhaust tubes or fuel lines with lower pressure together.
  • These tubes are also compatible with lower-pressure air, exhaust system, and liquid systems in the locomotive and boating industries.
  • You can also use these tubes to diminish trembling in solid lines.

Chapter 12. What are different types of Tube flaring?

The flaring tube fabrication is categorized into two different types:

1. Single Flaring

This tube end formation method is typically used to create a liquid-tight, airtight connection at the end of a tube. You can perform rotary or spinning techniques for a flared end, or just ram forming

2. Double-Lap Flaring 

It offers extra strength to the tube ends. Mostly used for the tubes are exposed to more stress and fatigue. The joint is created to have a larger diameter for the inner surface of the flare. An increased tube end diameter prevents it from restricting the flow characteristics of the system.

Some ram machines are considered as impeccably advanced tube end formers. They are constructed with the ability in being prepared with several tools. They can create different end forms on a single tool. 

Aside from exceptional power, a ram tube end machine is capable of progressive expansion or reduction of the tube for minimizing the tube OD (outer diameter). Thus, the technique is also termed progressive ram end forming.

Chapter 17. What is the principle of ram tube end former?

The ram tube end fabrication is carried out by loading the tube into some clamp dies. The clamps die contain cavities cut within them for the tube to fit in. As the end forming cycle starts in an end former, immediately the dies are closed. 

It will allow you to hold the tube in place during the process.

A shuttle with a single or a set of tools moves the tube forward. These tools are responsible for the formation of the tube’s end. They induce the metal to move rather slowly in the machine also referred to as cold flow. The metal follows the path created by the tools at minimum resistance.

The tube keeps moving until a sketch is prepared and separated inside the tool and forms the dies. 

Chapter 18. Are ram tube end forming machines worth it?

Having a Ram end formers can be quite advantageous. The machine can generate powerful wall thicknesses of approximately 0.500 by using its hydraulic power.  Some of the most premium end former models can provide almost 250 tons of force for end-forming.

The hydraulic power can considerably amplify their expansion and reduction range capabilities. You can get exceptional services as compared to other machines i.e. rotary or segmented method following end formers. 

Apart from its many benefits, the ram tube end forming machines possess some drawbacks as well. Depending on the material used for the tube, beads with tight or radical radii formation may be quite challenging. 

This all happens because the movement of materials into the radii profiles cut within the dies is difficult.

Chapter 19. What is the difference between ram tube end former and segmented tool sizing?

Most ram end forming applications are compatible with segmented tool sizing as well. However, these processes still have some important features with distinctive differences.

Ram tube end forming machines

Ram forming also known as bulldozing utilizes a powerful process. It is capable of driving a tapered plug on the interior or tapered cup around the exterior of any firmly held tube end.

If you require powerful and high-precision, long-lasting performance, ram tube end formers would be an ideal option. Ram-type tube end formers are proficient in constructing tubes having serious tolerances, concentricity, and offsets.

Segmented tube end forming machines

Segmented tool sizing affects the tube circumference outwardly. For tube OD reduction the process consumes a set of segmented dies. These dies are designed bigger in size.

You can use segmented tube end-forming machines for low-volume products. It doesn’t offer high-end forming precision. But it still works perfectly with lower capacity items. These machines contain eight finger tools power-driven by the mechanical drawbar.


Chapter 20. What is the difference between the rotary tube end former and the ram tube end former?

Both methods are used for effective tube fabrication, but differ in some aspects;

Ram tube end former

It is exceptionally powerful and functional end former. The machine provides working in both interior and exterior tube circumference. Heavy-duty ram machines are mostly used for mass production applications. They can efficiently create tubs having severe tolerance and offset.
