Tube bending

Cold bending is a traditional method for bending tubes and giving them a specific function or appearance. It is also the most commonly used method for bending tubes in serial production. The process involves pulling the tube through a hollowed out curve template, using a drawbar that has been hollowed out in the opposite direction as a lever. The drawbar and template form a “tunnel” that stops the tube flattening at the bend point. In order to ensure that the tube retains its shape at the bend point, we also use a mandrel that is specifically adapted for the inner diameter of the tube.

Compared with other production methods, such as cutting and joining tube parts, bending is a rational and cost-effective production alternative. Bendex has the tooling, the expertise, and the experience required to achieve a good result.

We are versatile

We precision-bend everything from round pipes to square tubes and elliptical profile tubes. Our modern machines with boost function enable us to bend with tight radii, high precision, and unbeatable quality.

Another important factor, apart from machine capacity, is tube quality. Choosing tube tube material of the right composition - e.g. the correct expansion values - is vital in order to ensure the best possible results.

We use various different methods depending on needs and requirements:

• Fixed radius: Traditional bending where we use a fixed radius disc.
• Free radius: In this technique, we shape the tube by rolling the material through moving rollers, which perfect for producing large, sweeping radii.
• Variable radius: Where a project requires the production of a part in different radius sizes, we use a free radius technique that allows us to vary the radius of the tube during a single bending cycle.
