Episode 5: Coins


Everyone knows it, everyone has it, either in the wallet or in the pocket: small change. Be it in the form of Euros, Swiss Francs, US Dollars or Russian Rubles – it is omnipresent in our everyday lives. Few people, however, know that strict quality standards apply to coin blanks. After all, the coins that come into circulation should be flat and plane, and the minting must be permanently preserved. 


At the German company Freiberger Eurometall GmbH, 9,000 tons of non-ferrous metals and steel materials are processed annually into around 3 billion coin blanks. From these, state and private mints all over the world produce circulation coins of every type and size. 


KOHLER strip leveling lines for flat coin blanks.


This is where the strip leveling plants from KOHLER come into play: Our plants ensure that the raw material is prepared by leveling - also called roll leveling - so that it can later be stamped into coin blanks without any problems and in high quality. In this process, the starting material is available as a coil and sits on a coiler. The strip material is unwound from the coiler and fed into a strip leveling machine. It then passes between rotating leveling rolls arranged offset at the top and bottom and is leveled. This both reduces the stresses in the material and at the same time ensures that it is flat and plane. After the leveling process, the strip material is transferred to a punching line. There, the coin blanks are punched out of the leveled metal strip and delivered to mints around the world.


KOHLER Maschinenbau GmbH was founded in 1963 in Oberweier in southern Germany and is a manufacturer of strip processing lines and part leveling machines. KOHLER has been part of the WINTERSTEIGER Group since 2011 and has been based in Lahr, Baden, since 2014.
