The waterpowered hammer mill in Hasloch at the Haselbach is the origin of the international high-tech corporation Kurtz Ersa. The HAMMERMUSEUM and the still working Iron Hammer tell a story full of passion to glowing iron.

HAMMERMUSEUM and Iron Hammer show living technology since 1779. According to the motto "Future needs Origin" the view back defines the position of today and tomorrow. You will obtain a first impression of the exhibition on this page.


Until the late 19th century, many iron hammers were located in the Spessart and Odenwald regions. These used wood, which was plentiful, and water power. An interactive model illustrates how water power is controlled through sluices. However, only two iron hammers survived the turn of the 20th century.


Everything that is worth knowing about the iron hammer in Hasloch is included in the second chapter: how do a tilt hammer or a tail hammer work exactly and how is metal shaped using these? Historic forgings are on display, such as bell tongues, pliers and drag shoes. At an interactive station, visitors can test their strength against that of the iron hammer.


As early as 1852, the Kurtz family expanded its iron hammer into a foundry. Household items and agricultural machinery were produced, as well as railway castings. This first diversification enabled the company to survive. Today, the foundry is still an important mainstay.


In the 20th century, thanks to its enlarged foundry and engineering works, the "Joachim & Kurtz, Maschinen- und Apparatebaugesellschaft" was active at a national level. Models of shape moulding machines and of a low-pressure casting machine, infographics and videos, as well as many original exhibits, illustrate the production processes.


From historic manual soldering irons to wave soldering systems, including the ERSASCOPE, with millimetric precision: this chapter explains the development and functioning of soldering technology. The museum features a remarkable interactive soldering game, with which a radio circuit can be soldered and put into operation.


The iron hammer in Hasloch has developed into an internationally active Corporation with worldwide presence. When visitors push a button, a large world map shows the sites. The exhibits, which change regularly, also provide information on new production processes.
