Tube Bending & Fabricating

At Trunex Limited, we provide precision tube bending, metal fabrication, and CNC machining services with a focus on accuracy and reliability.
Our team delivers end-to-end solutions — from raw material cutting to finished assemblies — ensuring consistent quality, tight tolerances, and dependable performance.

Industrial Tube Bending Services in Action

We are equipped with state-of-the-art CNC tube benders with touch screen controls, which allows us to produce complex bent parts. We use our existing tooling systems for bending and fabricating that not only facilitate faster part turnaround but also reduce tooling expenses. With 15 tube benders of various types and sizes, we fit the right machine to the product and well as provide redundancy to guarantee delivery in case one machine requires maintenance.

Moreover, we have a dedicated customer support team to help you out with queries regarding in-house bend-die information.

Tube Bending Specifications

The Trunex Limited tube bending process provides standard bend radii from tight 1D mandrel bends to large, sweeping roll bends and free form bending. We also offer bending of pre-coated and painted parts. We fabricate metal tubes of length up to 27 feet and assemblies up to and over 80 feet. Mild steel, stainless steel, and aluminum are among the materials we use to produce these tubular components.

Design Assistance

Some basic ideas that can help in reducing the overall cost of a part by designing the part to be manufacturing friendly are provided below. For a more in depth analysis send us your drawings, or call one of our engineers.

Tube Bending Considerations

CLR- Center Line Radius: Typical CLR is 3x the OD of the tube without mandrels. It is possible to bend on a 1 or 2xD bend, but not without more complex tooling. Tooling costs also increase when comparing a plug mandrel to 3-ball mandrel & wiper die. The tighter the radius, the more tooling required and the more expensive the part. Use the same CLR for all bends unless prohibited by design restraints.
Straight between bends: Allow 3x the OD of straight for clamping between bends and from the edge of the tube. This reduces the overall cost of part by reducing additional trim operations and increasing the bend rate. Bends closer than 3xD require compound tooling increasing tooling cost and reducing bend rates
