ISO 9001 Certification


Quality has to be part of a company´s mind set before it can be realised. Sophisticated product concepts and technical excellence guarantee highest functionality and quality level for all goods that we produce. From the individual unit to the serial product, we produce 100 % of our products at our factory in Wertingen, Germany. The components we have to buy are sourced under strict quality criteria from respected German and European manufacturers. Our high quality standard is a guarantee for a secure feeling and satisfaction of our customers.




On the 20th August 2008 WDT received an official certification of registration to  the International Organisation for Standardisation (ISO) for Quality Management Systems (9001). The effectiveness of our systems were approved by the accredited certification auditors, DEKRA Certification GmbH.

During the certification, we analyzed, defined and, where necessary, reorganized all processes of the company, using the support of the management systems consultancy, asquana GmbH. This is a further milestone in the history of the company.

The main goal of WDT is to ensure the satisfaction of our customers by providing stable and documented quality control systems of our products as well as the continuous optimization of our processes. This is not only a fundament of our strategy and goals but also a guideline for the daily work of all staff members.
