DOERING. Leading through performance.

As an independent, internationally active enterprise specialising in iron castings, we have been convincing customers for more than 150 years with our performance in the fields of job casting, pattern-making, grinding media, and valves. Our many years of know-how and our experience enable us to produce tailored solutions for our customers from the automotive, toolmaking, mechanical-engineering and mineral processing industries - true at all times to our high DOERING quality standard.

Job casting

In conformance with our customers' specifications, we offer hand-moulded castings from a variety of materials that may be made by the lost-foam or the conventional mould process.



Pattern-making comes before casting. Based on available data records, we make the patterns in our own pattern shop.


Grinding media

For grinding down minerals and ores we offer our cast, highly wear-resistant DOERING CYLPEBS.



Made of iron and other casting materials, DOERING heavy-duty valves have had an excellent track record for many years in a wide range of installation situations.
