Our Scope of Work

Body shell

The fundamental element of every vehicle is the bodywork. In today’s passenger cars, this takes the form of self-supporting bodywork, meaning the chassis and the structure are merged into one unit. In this context, the paneling, reinforcements, mounting plates, and profiles are permanently attached to each other using various joining techniques, such as gluing, spot welding, laser welding, or soldering. In collaboration with the CAE department, during the development process, an optimization of the body shell takes place with regard to vehicle safety and passenger protection using various crash simulations.

Door shell

The doors of a vehicle are an important, but autonomous, component of the bodywork with essential functions regarding safety and crash protection. When designing the components, various factors such as manufacturability, joinability, or the arrangement of units (package) play an important role.

A selection of our services in this field:

without frames, with frames, or as sliding doors using a sheet metal construction
inside of the door can be designed either with or without a door module
locks, hinges, external mirrors and decorative trim
seal and the determination of the hinge axis with analysis of the door recess
functioning crash system in coordination with the entire body shell

Engine hood

In addition to serving a visual purpose (design), the engine hood (also known as the radiator hood) also serves the important function of pedestrian protection or to improve the cooling of the engine compartment. When designing the components, various factors such as manufacturability, joinability, or the arrangement of units (package) play an important role.

Hatchbacks / Trunk lid

There are various variants for the trunk compartment or trunk lid on vehicles, ranging from a notchback as on sedan cars or hatchbacks and station wagons to tailgates/hatchbacks on vehicles with an open loading area. In addition there are different materials, discs, stops or locks, dampers or springs.

Modularity

From the point of view of economic efficiency and industrialization, nowadays, scalable and modular construction solutions, rather than individual ones, are in demand in vehicle construction. Especially for small and medium product volumes, modularization offers a cost-effective solution for development and production in terms of crash testing, ease of repair, and tool diversity.

During the development of the entire vehicle, if it’s possible to derive the development goals from the subsystems and break down the modularization to the components or subsystems, these synergies can then be used in the various subareas, such the chassis and E/E components.
