Using the ZHU250TOP
(PresseBox) ( Ulm, )
Deutsche Edelstahlwerke in Stuttgart, Germany is a member of the SCHMOLZ + BICKENBACH AG group of companies which, with 150 years of experience, roughly 11,000 employees and sales exceeding € 4 billion, is the world's largest producer, processor and distributor of special steel long products.

The company offers its customers a ‘one-stop-shop’ for heat treatment processes including plasma nitriding. Leading Major German automotive sports car manufacturers rank amongst their list of prestigious clients, and Zwick is proud to have equipped the laboratory with all of its hardness testers - the most recent being the premier ZHU250 TOP Universal Hardness Tester.

This machine has expanded the capability of the laboratory to carry out Rockwell, Vickers, and Brinell tests, and includes an innovative revolver system incorporating four indenters. Similar systems require three or more objective lenses to cover the application range but, due to Zwick’s unique digital zoom technology, the ZHU250 requires only two. This enables a fast throughput of tests, and many different types of test can be carried out on the same machine with very high accuracy and repeatability. The test results are also sent to the host computer system via a computer interface.

“A major reason for purchasing the ZHU250 was the excellent manufacturing quality, and the reliability of our existing Zwick Roell products. This convinced us to purchase this new machine, and as a result we have saved cost, improved our throughput and increased our business significantly” explains Mr. Wessel Völcker, Deutsche Edelstahlwerke‘s Production Manager.
