More than 135 years of Strobel Quarzsand - a long tradition

From 1876 to the present day, four generations of the Strobel family have led the silica sand plant with foresight, determination and great success.

Since 1994, Liselotte and Günter Forster are the fourth generation to run Strobel Quarzsand GmbH. With great dedication and together with 70 skilled and highly motivated employees we serve the needs of our partners.

Our foundry sands are used as a basic material for producing molds and cores with the binding agents such as bentonite, synthetic resin or water glass. They constitute the basis for ready-to-use sands, oil-bound or coated in synthetic resin, for a wide range of different uses up to rapid prototyping. This type of sand is used in the vehicle industry, in mechanical engineering but also in synthetic casting

In addition to the standard grades in the grain size from AFS 40 to AFS 140, we also offer the finest special sands up to AFS 250 as an additive in green sand.

For developing, optimizing and monitoring our foundry products, we have an application laboratory which allows examination of both nuclear parameters and moulding material parameters.
