First address for interior testing and engineering

The interior components of a vehicle have a direct impact on the driving experience as well as the well-being of the occupants. The look and feel of surface materials, operating instruments, door panels, etc. play an important role, but so do acoustic perceptions, e.g. As an experienced and highly flexible interior testing and engineering partner, we support our customers in testing and optimizing all factors: from the individual component to the overall project and from the concept phase to series support.


Comprehensive range of services

Our customers include most OEMs and system suppliers worldwide, whom we support in development and testing. With over 40 years of experience, we see ourselves as an engineering development partner and interface between customer and development. In addition to testing and engineering the entire interior, we can also take on projects from concept planning to homologation support. The competencies of our team extend to the operation or development of test benches, emission testing of materials and the revision or development of test specifications.

Our focus areas in the interior are:

  • Cockpit and center console
  • Door panels
  • Headliner, sun visors, mirrors
  • Floor and pillar panels, trunk
  • Soundproofing etc.

Tested and evaluated: service life, series installation, endurance runs

Lifecycle testing

  • Vibration tests uniaxial and multiaxial (shaker, MAST)
  • Dynamic and climatic protection of interior components
  • Resonance determination, frequency response analysis
  • Road driving simulation
  • Noise analysis (temperature-conditioned NVH tests)
  • Transport simulation according to MIL STD
  • Electrical / electronic parameter monitoring

Evaluation of series installation

For the close-to-series construction of our test samples for validation, all screw connections are assembled using a calibrated torque wrench over the entire screwing process. Speed ​​and torque are decisive here in order to evaluate not only the strength but also the durability of the samples.

Robotic endurance tests

To validate moving parts, such as center armrests, glove boxes or vents, endurance tests are carried out on individual components or vehicles using robots. The movements can be carried out with exactly reproducible speeds and trajectories. All relevant parameters such as forces, moments or distances are measured, documented and analyzed.
