Quality Management

We owe our high standards of quality to an extensive system of quality assurance measures. They are certified against and aligned with the demands of DIN ISO 9001:2015. We have documented our quality management system in a process-oriented management manual, which we are happy to make available to interested customers. In scheduled internal audits and reviews, the executive body reviews and assesses the effectiveness of the management system. We have modern facilities at our disposal for the varied tests in goods receipt, production and final inspection and for product development.

As such, we are able, for example, to directly depict, present and measure the behaviour of our commutators under variable operating conditions (temperature, speed) on our dynamic centrifugal test bench. In the interests of a high level of customer satisfaction, we work continuously on the improvement of all quality-relevant processes.

All commutators and slip ring bodies delivered are subjected to 100 % of the electrical test.

Upon request, we can add certificates of the test to your delivery. Here is an example certificate.

Testing equipment

A variety of equipment are used to ensure our high quality standards. These have sometimes been specially manufactured to meet the specific test criteria.
