Our Services

Test stands and services to improve subjective and objective product quality

This is accompanied by the use of standardized material pair testing and annoying noises analysis to avoid contact pairs that have a tendency for the stick-slip effect. Different materials within a vehicle do feel the same – in technical speaking this is called “material match” - with the help of our haptics system, we are able to measure relevant physical parameters, which are relevant to touch haptics and create a so-called haptic fingerprint of the material surface. With the volumeter from RION, we offer an acoustic determination of the density of solids for all relevant applications.

Research and Development

Experts at work

In order to secure our technological leadership, we carry out publicly funded research projects. The findings are used to further develop our test benches in the areas of materials testing and touch haptics.

Quality through management

ISO 9001:2015

The assurance of process quality and product quality in our company, through the corresponding certifications, accreditations and approvals, such as ISO 9001:2015, is a very important to us.

We think ahead . . .

…and support our customers with measurement technologies and services for acoustical and perceived product quality, as well as their improvements.

In this context, product quality is defined by subjective and objective factors. ZIEGLER makes it possible with its testing technology to measure both the objective and the subjectively perceived quality and to convert it into comparable key figures.

These testing techniques and services support the complete life cycle of products. Starting with the planning and enables long lasting quality control.

After being founded by Rainer Ziegler in 1972, the company initially focused on sound and vibration, starting with Dr. Hans-Jürgen Daams. After a further focus on Squeak and Rattle, the company is taken over by Jens Herting and Patrick Schimmelbauer in 2016, who strategically focus on "improving the objective and subjective quality of products". Ziegler has been operating under the name ZIEGLER perceived quality GmbH since 2024.
