Lightweight construction

Lightweight construction refers to the deliberate reduction of the mass of a component or structure without compromising the functionality and load-bearing capacity required for the application. The key factor is therefore not merely the lowest possible weight, but an optimal ratio between component mass and functional performance.

Lightweight construction can be achieved through the selection of suitable materials, load-appropriate component geometry and adapted manufacturing processes. Cold forming offers interesting possibilities in this regard, as materials can be specifically formed into complex geometries and their mechanical properties can be influenced by the forming process.

At MN Kaltformteile, material, geometry and manufacturing process can be considered together right from the component and process development stage in order to develop cost-effective and material-efficient component solutions.

Lightweight construction through cold forming

Lightweight construction begins as early as the design stage of a component. This involves investigating which geometry and which material are required to achieve the required function and load-bearing capacity with the lowest possible component mass.

Cold forming can offer various approaches to this end. Through targeted material distribution, for example, hollow geometries, different cross-sections, collars or functional contours can be produced. Material can thus be deployed precisely where it is needed for the component’s function.

At the same time, plastic deformation leads to work hardening of the material. The resulting mechanical properties can be taken into account during component design. The choice of a material with a lower density – such as aluminium – can also represent an opportunity for weight reduction, depending on the requirements.

At MN Kaltformteile, such potential is already taken into account during the development and manufacturability analysis stages. In this way, the material, geometry and forming process can be coordinated, and existing components can be optimised, where appropriate, in terms of weight, material usage and manufacturing process.

Lightweight construction: Questions and answers

What does lightweight construction mean?

Lightweight construction refers to the targeted reduction of the weight of a component or structure whilst maintaining the same or sufficient functionality and performance.
How can the weight of a component be reduced?

Component weight can be reduced, amongst other things, by selecting a suitable material, designing a load-optimised geometry, using hollow geometries or distributing the material in a targeted manner. It is crucial that the required function and mechanical load-bearing capacity continue to be met.
What is the significance of cold forming for lightweight construction?

Cold forming makes it possible to shape material precisely into complex geometries and load-appropriate geometries. At the same time, the mechanical properties of the material are influenced by the forming process. Both aspects can be taken into account when developing weight-optimised components.
Which materials are suitable for lightweight components?

The choice of material depends on the mechanical, thermal and functional requirements of the component in question. In addition to steel, aluminium and suitable aluminium alloys may be of particular interest for lightweight construction applications due to their low density. In the case of heat-treatable aluminium alloys, the mechanical properties can also be influenced by targeted heat treatment and adapted to the requirements of the component. The key factor is the interaction between weight, strength, geometry, manufacturing process and, where applicable, heat treatment.
Can existing components be optimised for lightweight construction?

Yes. For existing components, aspects such as material, geometry and manufacturing processes can be examined for potential optimisation. For example, solid sections can be replaced with suitable hollow geometries, materials can be reassessed, or machined geometries can be converted to a cold-formed design. The prerequisite is always that the component’s functional and mechanical requirements continue to be met.
