For over 40 years, THIELMANN GRAPHITE GmbH & Co. KG has been selling graphites and graphite products, with the main emphasis on natural graphites. In 1982, the company moved into the premises of Becker-Pennrich KG, which has also been working with graphite for more than 40 years, with the main emphasis on processing synthetic graphites. As early as 1995, the quality management system was certified in accordance with DIN EN ISO 9001 by DQS (Deutsche Gesellschaft für Zertifizierung von Qualitätsmanagementsystemen mbH) [German Association for Certification of Quality Management Systems Ltd]. To meet the exacting demands on the quality of the graphites that we supply, our own testing laboratory has numerous facilities for verifying quality as part of incoming and outgoing goods inspection. Our own grinding and sieving facilities enable us to respond flexibly to user requirements.
