Metals are part of both everyday life and a luxurious lifestyle. They are used in the most advanced technology as well as in the most basic packaging material. Our exhibition explains the sophisticated technology that lies behind all metal products.

Foundry and Metals

People have been working with metals for around 10,000 years. At first, only “native metals” were found on the surface of the earth. These pieces of metal attracted attention because of their great weight, lustre and malleability. Then around 6,000 years ago at the latest, people began to extract metals from their compounds, the ores. Thanks to their special material properties, metals have since become indispensable to mankind.

The exhibition chronologically traces the evolution of the production and further processing of metals.

72Of the 94 natural chemical elements, 72 are metals – ca. 50% of these have technical applications.

2,000°CThe highest temperature reached in a blast furnace during the production of pig iron.

1,000kgAnnual global production of osmium – one of the world’s rarest metals – is only around 1 tonne.

Powder Metallurgy / Stainless Steel

Stainless steels can be found everywhere and are a sustainable material. They have a long life and are very easy to recycle.

Activities

Demonstration Foundry

Here, visitors can watch an actual casting process live! The function of the aluminium melting furnace is explained before the casting process starts. Liquid metal is then poured into prefabricated casting moulds and the result is a finished casting. For group bookings, a mould can also be made from sand first and then filled with metal.

Participation in this demonstration is free of charge for individuals and families, registration is not necessary. The meeting point is beside the Demonstration Foundry. Check the schedule on the day of your visit to see when the demonstration will take place.

Groups should book a foundry demonstration in advance of their visit.
