The bodywork plays one of the most important roles in the development of a new vehicle. Lightweight construction concepts, such as mixed constructions, reduce the overall weight. The challenge is to keep control of tolerances such as the accuracy of individual parts, the clamping, spot welding, folding and the drying of parts with cathodic dip coating (CDC drying). Variations in functional dimensions are visible and reduce the quality. In mixed constructions with aluminium, deviations from tolerance due to differences in thermal expansion can occur during thermal processes. This can influence the quality of seals, closing forces and wind noise. The deformations and displacements of the components in the test chamber are determined with optical measuring methods. The oven also has a large window.
