Our Company

Our company Siegfried- W. Grunwald e.K. Erodiertechnik & Werkzeugbau is a young corporation in the field of tool manufacturing. Since our formation in 1992 we render services from the concept and the prototype to the point of a series production part.

In the last years we have expanded our connections continuously. We always try to expand and improve our service portfolio. Moreover we make investments higher- than-average in new manufacturing technologies.


Since the internal development of our Multiformer it has become more and more our core business. We are proud of our product because we could convinced more and more vehicle manufacturers of the advantages of our product. We are particularly happy that we can serve international customers as well.  You can find a summary of the Multiformer references here.

We can number among our customers basically vehicle manufacturers and their suppliers but also companies who work plastic and quality-consious individual customers.

We are looking forward to any tasks one can assign us. Moreover we are always prepared to develop our products constantly further in order to meet you and the required products.

We would like to realize your concepts and ideas, too.
