On January 1, 1949, Karl-Wilhelm Burgdorf founded the company Dipl.-Ing. Karl-Wilhelm Burgdorf, Abschreckhärtetechnik, Nienburg a. d. Weser, in the turmoil of the post-war period.
His decision to found the company was based, on the one hand, on the experience he had acquired during his work for international mineral oil companies before and during the Second World War and, on the other hand, on the opportunity to use two patents that he had been significantly involved in developing.
On the basis of these findings, Karl-Wilhelm Burgdorf developed the first high-performance quenching oils with controlled cooling behavior.
These new quenching oils benefited German industry, which demanded high-quality, high-performance quenching oils with long-term stability due to a post-war shortage of alloyed and easily hardenable steels.
Due to an unfavorable living and working situation in Nienburg, Karl-Wilhelm Burgdorf quickly looked for a larger home for his extended family and the newly founded company. To this end, he made personal contact with the then Lord Mayor of Stuttgart, Arnulf Klett. In the interests of rebuilding Stuttgart as a business location, he was given a building for his family and the company at the instigation of the Lord Mayor, which they moved into in 1950.
BURGDORF was carefully and purposefully built up by him, from the end of the 1960s by his sons the brothers Dipl.-Kfm. Hannes Burgdorf and Dipl.-Ing. Eckhard H. Burgdorf and since 2005 by Dipl.-Ing. Rainer Braun and Dipl.-Kfm. Frank Burgdorf into an internationally active specialist company for heat treatment technology of the highest rank.
Building on the high-performance quenching oils already introduced to the market, BURGDORF has expanded its product portfolio over the years with the development of synthetic quenching oils, vacuum quenching oils, polymer quenchants, special cleaners and corrosion inhibitors. With the acquisition of NÜSSLE GmbH & Co KG and OSMIROL GmbH, we expanded our product portfolio to include high-quality stop-off paints and gained internationally recognized polymer quenchants expertise. Following the takeover of the quenching agent activities of Carl Bechem GmbH, Hagen and Georg Oest Mineralölwerke GmbH&Co.KG, Freudenstadt, we now operate worldwide in the field of materials technology and heat treatment under the name "bon Group".
Achieving results of exceptional quality for our customers - this is not only because of our high-quality product range.
