ZOLLERN CASTINGS <strong>TECHNOLOGY</strong> – PERFORMANCE, EXPERIENCE AND INNOVATION 2 3 In the field of castings technology, the ZOLLERN Company is not only one of the foremost names in Europe but also a highly respected exporter to some of the most important industrial notions in the world. After all, we have been making castings for around one hundred years. ZOLLERN helped to shape every stage in the development of the technology, from the production of simple cast iron at the end of the 19th century to the most modern technologies in use today. Our origins, however, go a lot further back. Prince Meinrad II of Hohenzollern founded the smelting plant which bore his name and consisting of a blast furnace and hammer mill as long ago as 1708. During the 280 years since then, the original iron works at Laucherthal (near Sigmaringen) has developed into a Company employing 2000 people and operating on an international scale. Today, ZOLLERN concentrates primarily on producing castings by a variety of methods (investment, sand, shell, mould, Shaw, continuous and centrifugal); it also has forging and drawing facilities at its disposal. At the same time, ZOLLERN is also well known as a manufacturer and supplier of drive systems, handling equipment and machine components, with the result that the expertise obtained from all the industrial sectors which the Company supplies is utilised synergically to the advantage of customers for ZOLLERN castings.
