Curved aluminium profiles, ready for installation, direct from the factory

Do you require extruded aluminium profiles with a specific radius, high repeatability and reliable lead times? Aluminium Laufen AG Liesberg bends your aluminium profiles in-house immediately after extrusion – precisely, efficiently and tailored to your production run.

The bending process: controlled, measurable, reproducible

When bending aluminium profiles, the cross-section, wall thickness, desired radius, tolerances, bending direction, alloy and temper condition all play a crucial role.

Using a modern roll-bending machine, we bend extruded aluminium profiles into the desired 2D shape. In roll bending, the profile is guided step by step over rollers and formed to the defined radius – a process particularly suited to long profiles, uniform radii and repeatable production runs.

The individual production stages are coordinated with each other to ensure process reliability:

Extrusion → Profile bending → Heat treatment (depending on the alloy, this step takes place before profile bending) → Machining → Surface finish

For you, this means: less coordination, less supplier management and clear accountability for the finished profile.

Send an enquiry
Please send us the drawing, profile geometry, alloy, desired radius, tolerances, quantity and requirements for machining and surface finish.
Feasibility assessment
We evaluate the cross-section, wall thickness, radius, bending direction, alloy and condition. If necessary, we advise on the optimal design of the profile.
Coordinating extrusion and bending
Profile production, the bending process, heat treatment and subsequent processes are technically coordinated with one another.
Start the bending process
Once the profile has been fed into the bending machine, the bending process is monitored, adjusted where necessary and documented to ensure consistent production quality for subsequent orders.

Bending in the T4 or T6 condition

Our bending machine allows bending in both the T4 and T6 conditions. For tight radii, bending in the T4 condition followed by heat treatment to T6 or T66 is often recommended. The specialist furnaces required for this, as well as the measuring systems for testing hardness, strength and other mechanical properties, are located at our plant in Liesberg.

Your benefit: Greater design freedom for tight radii and defined strength values following heat treatment.

Bended aluminium profiles for technical components and visible profiles in series production

Bended aluminium profiles open up additional design possibilities. They are suitable for indoor and outdoor applications, for example in the transport sector, in façade construction, in the automotive industry and in many other sectors.

Some areas of application for our bended aluminium profiles include:

Cable cars
Means of transport such as buses, trains and trams
Container frames
And many other products across a wide range of sectors

You will receive your ready-to-install bended profiles with short delivery time, from a single source and ex works.

Process reliability guaranteed for every single profile

During the bending process, once feasibility has been checked, we can use lateral guide rollers to compensate for deviations or even bend the profiles in the third dimension if required (conditional 3D bending).

The actual radius is measured continuously or cyclically. The target radius is achieved through automatic correction and is incorporated into the bending process for the next profile. This guarantees a consistently uniform radius within the required tolerance for the entire series.

The bent profiles are inspected in accordance with defined testing procedures, including individual quality requirements, prior to dispatch.

Why order bent aluminium profiles directly from the factory?

Predictable costs instead of the risk of scrap
New profiles need to be run in during the bending process. Depending on the geometry, radius and tolerance, this can result in scrap. It is precisely this risk that often makes external bending processes difficult for buyers to budget for.
You receive a firm quotation and thus a reliable basis for calculating the cost of parts ready for assembly.
Precise radii through a controlled bending process
Our state-of-the-art roll bending technology continuously or cyclically measures the actual radius during the process. Deviations are automatically corrected and incorporated directly into the bending process for subsequent parts. This ensures reproducible results, from the first to the last profile in a series.
The result: consistent radii, stable tolerances and reduced rework in your production.
Ideal for small and large production runs
Whether for recurring series production or smaller batch sizes (from 50 pieces): the process is designed for reproducible quality. Once settings have been determined, they are saved and can be reused for subsequent orders.
This is particularly important when profiles are reordered identically over extended periods.
Technical advice even before production begins
To ensure a reliable feasibility assessment, we consider all relevant technical and economic factors.

Among other things, we review the following with you:

Profile cross-section and wall thickness
Desired bending radius
Bending direction and profile height along the bending axis
Alloy and heat treatment condition
Requirements regarding tolerances, surface finish and further processing
Economically viable batch size and suitability for series production
This helps you avoid unnecessary rounds of corrections and establishes a robust technical basis for your procurement

More than just bending: ready-to-assemble aluminium profiles direct from the factory

On request, Aluminium Laufen AG Liesberg can carry out further mechanical processing steps following the bending process. This results in profiles that are precisely tailored to your assembly and functional requirements, including the desired surface finish.

Depending on the area of application, design specifications and functional requirements, bent aluminium profiles can be finished with a variety of surface treatments, for example:

Anodised surfaces
Powder-coated profiles
Wet-painted surfaces for custom designs
Silver-plated profiles for technical applications
Electrolytically polished aluminium surfaces
Special coatings to specification
Mechanical surface treatments such as brushing, grinding, blasting or textured finishes

Frequently Asked Questions about Profile Bending

Can all aluminium profiles be bent?

Many extruded aluminium profiles can be bent. The key factors are the profile geometry, wall thickness, alloy, temper and the required bending radius. We will assess the technical feasibility based on your drawing.

What is the minimum quantity for placing a bending order?

The minimum order quantity specified in our scope of services is 50 pieces. The process is particularly cost-effective for series production and repeat orders, as saved machine settings ensure consistent results for follow-up orders.

Can multiple radii be achieved in a single profile?

Yes. The radius measurement system allows one or more different radii to be measured along the same profile.

Can profiles be further processed after bending?

Yes. On request, bent profiles can also be machined and supplied with the desired finish.
