| Programmable Radius Tube Bending Tooling |
|---|
| Programmable radius tooling is available for the tube sizes listed below and is intended for large radius CNC bending. As a general starting point, bend radii are approximately eight times the outside diameter for round tube and 10 to 12 times the outside dimension for square tube. Feasibility and repeatability depend on the material, wall thickness, bend angle and complete part geometry. Fixed radius tooling is preferred when closer dimensional control or higher repeatability is required. |

Why Choose Seaborn Manufacturing for Tube Bending
Materials of Our Kitchener-Waterloo Clients Used for Tube Bending
Steel Tube Bending Kitchener-Waterloo
Steel remains the most widely used material for Tube Bending Kitchener applications. From standard grades such as ASTM A1011 and 44W to high-strength alloys like 4130 and 4140, steel tubing is used for structural and mechanical applications. You see it in everything from equipment frames and safety devices to furniture, making it the backbone of many fabricated assemblies.
Stainless Steel Tube Bending in Kitchener
Stainless steel does well in tube bending when handled correctly. It is commonly selected for its corrosion resistance and visual appearance in exposed applications. In the Kitchener , Waterloo manufacturing region, stainless tubes are often used in equipment, and enclosures, for food or chemical handling.
Aluminium Tube Bending in Kitchener-Waterloo
Aluminum tube bending requires careful material selection. The most common grade of aluminum tube is 6061-T6 and is not suitable for forming, or tube bending. For your Kitchener tube bending projects, we focus on sourcing the correct aluminum grades such as 6063-T5. Our fabrication facility in Waterloo is ready for all your tube bending needs.
Wall Thickness and Tube Bending
At Seaborn we prefer working with slightly thicker walled tubes. It is much easier to form a tube with a 3mm ( ⅛”) wall than one with a 2mm 0.08” wall. The tubes hold their shape better and form far easier.
Square Tube Bending Waterloo
Square tube bending adds another level of complexity and consideration. For many projects the tube’s inner and outer wall collapsing to the center may be acceptable. For those that need a cleaner appearance controlling the tube wall requires the right tooling and a lot of tube bending expertise. Our Waterloo based tube bending service has a lot of experience with forming square tubes.
Tube Bending Applications Across Industries
Tube Bending in the Kitchener-Waterloo area is especially popular in these local industries:

Tube Bending Services FAQ
We provide CNC tube bending for various materials including steel, aluminum and stainless steel.
CNC tube bending base line and generally the most cost effective tolerance would be to follow the perfect part path within an ⅛” or 3mm. This is for a part with multiple bends on different planes. The end position of tube bending and even the travel path can be held to tighter tolerances but cost will go up. We frequently hold the tube end position to end position to better than 1.5mm / 1/16”.
Minimum bend radius depends on multiple factors such as wall thickness, material and tube size. As a general rule, tighter radii bending requires more tooling and has a higher failure rate. . At Seaborn Manufacturing, we regularly work with radii down to approximately 2.5x–3x tube diameter depending on the application, while maintaining part integrity. Avoiding the min is better when it is possible.
Yes and to a limit. Multi plane bending is a core capability of our CNC tube benders. They all can rotate the tube between bends. All our production tube benders are also double stack benders, this means they can carry two bend radii at the same time. The dies should be made together to be used in this manner. We also have the ability to use programmable bend radius but these take far more set up and development on every new lot of tube and are limited to roughly 12 times the tube diameter for a centerline radius.
To quote accurately, you should provide a dimensioned and toleranced drawing. For quoting a PDF is ideal. Make sure to include the material, tube size, wall thickness and quantity being ordered in each release. If you are buying thousands annually let us know but for most jobs the release quantity will set the price.
The perfect tube bend drawing would provide the center the distance for the start of each bend and the distance from the end of the last bend to the start of the next bend. The centerline radius of the tube as used in the drawing. How much the tube is rotated between bends if all bends are not flat on a single plain.
For our tube benders the min straight section from the end of one bend to the start of the next is 3.25” to allow for the tube benders clamp. As the tube gets larger and also as the bending radius gets larger the straight section needs to become longer. Typically the straight section between bends should not be less than 3.5 times the tube diameter.
Tube bending is the forming of tube around a central die while encapuslating the tube so it maintains its profile.
Tube bending most commonly is for mild steel. Stainless is well suited to tube bending and some grades of aluminum bend well. Copper, Inconel alloys, and many exotics are and can be used in tube bending.
Same as every job. Tooling cost need to be addressed first if stock tooling can not be used. After that is set up time to instal tooling and prove the first formed parts. Scrap cost of parts expected to be lost in set up. Then finally the run cost per part. The cost per part does not change throughout a run but how many pieces the initial costs are amortized over has a big effect on piece price.
