History

Roell & Korthaus have been involved in materials testing since 1920. Zwick began building machines and instruments for mechanical materials testing in 1937. The company founded by Professor Seger in 1876 evolved into the present-day concern Toni Techni. Roell and Korthouse, along with Toni Technik, have been part of the Zwick Roell Group since 1992. In July 2001 the group become a corporation under the name of Zwick Roell AG, incorporating Zwick, Toni Technik and Indentec Ltd. Acmel Labo, the French manufacturer of laboratory instruments for the cement, lime and plaster industry, has been part of the group since May 2002. Zwick/Roell AG acquired the German company GTM in 2007 and Messphysik of Austria in 2006. In 2014 ZwickRoell opened its new factory in Taicang, China, some 50 km north-west of Shanghai. Here, on a site totaling around 2,000 m², testing machines and instruments will be developed and assembled for the Chinese and world markets.
