Tube Bending


The Auto Components bending process provides standard bend radii from tight mandrel bends to large, sweeping roll bends. We also offer bending of pre-coated and painted parts.

Auto Components is equipped with state-of-the-art CNC tube benders with touch screen controls, which specifically produce formed tubes. We use our existing tooling systems and also manufacture toolings to suit the specific customer requirement for bending and fabricating that not only facilitate faster part turnaround but also reduce tooling expenses.

Designing 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
