Single-piece and small-batch castings for the agricultural, electrical, construction and mechanical engineering industries – and a long tradition of decorative and functional cast iron.
We produce grey cast iron castings weighing from approx. 0.1 kg to approx. 350 kg, with an annual production capacity of 900 tonnes. Today the foundry mainly supplies castings to the agricultural, electrical, construction and mechanical engineering industries. At the same time, we have a long tradition in decorative and functional cast iron (benches, posts, bicycle stands, manhole covers, etc.).
Exports currently account for around 35 % of our output, mainly to Italy, Austria, Germany, Switzerland, France, Slovakia and Slovenia. We pride ourselves on a customer-friendly approach and fast, flexible handling of our customers’ requirements.

We support
The entire process takes place under one roof – from melting in cupola furnaces through moulding and core making to fettling and quality control.
The melting shop is equipped with two cold-blast cupola furnaces with an inner diameter of 700 mm and a maximum output of approx. 2.5 tonnes of molten metal per hour. The drum-type pouring ladles hold 800 kg of molten metal.
We mould with bentonite-bonded green sand.
Cores are made by hand or on two core shooters.
Shot blasting on two belt blast machines, a table blast machine and a hanger-type chamber blast machine. Finishing on bench grinders or by hand in fettling booths.
Patterns are made by our long-standing, proven suppliers. In-house we carry out only partial repairs and modifications of patterns.
Castings can be primed at the customer’s request.
Casting quality is ensured by spectral analysis and Brinell hardness (HB) testing; tensile testing verifies material strength on request.
