OUR QUALITY MANAGEMENT 

 

 

                                                Our company is certified to ISO TS 16949 and has an experienced team to ensure the quality of our products. In addition to our competence in the materials sector, our fully equipped metallographic laboratory is the heart of our quality assurance operations. That puts us in a position to assist you from start to finish – from material development to series production – and to offer you advice and practical help in all matters relating to materials. We have four tensile testing machines – three of which are electronically controlled – for mechanical-technological testing in the range from 25 N to 1,000 kN, Test Class 1. Depending on the requirements, hardness testing is performed by the Brinell, Vickers and Rockwell (C and B) methods. The machines are inspected annually by an accredited company approved by the DKD (Deutscher Kalibrierdienst). For metallographic tests (microstructure/purity), we use two Leica light-optical microscopes with magnifications from 25x to 1,500x. Macroscopic examinations are performed using a Leica DM205C stereomicroscope with a magnification of up to 104x. The TEST MASTER PRO from Oxford Instruments Analytical GmbH is available for standard analyses. The specimens for metallographic tests are usually prepared by wet cutting (cutting-off machines from Struers and ATM), followed by grinding and polishing. A hot mounting press (Struers) and a grinding/polishing machine (ATM) with individual and central force application are used for specimens that have to be specially prepared using a diamond suspension.
