Our foundry sands - in a class of their own
It is the absolutely unique combination of the grain shape with its rounded edges, the smooth grain surface and the high sintering point that make our silica sand so valued and proven. This unique qualitative position allows sophisticated foundry casting of the very highest level and, last but not least, it is therefore always the first choice when it comes to high-grade foundry products.
The highest raw material quality for your production
The foundry sands from our other deposits do of course also meet the high quality requirements of our company and, needless to say, are suitable for all self-, heat- and gas-hardening processes. Our quality criteria for them are strict and ensure consistently high quality.
- high SiO2 content (> 99%)
- low annealing loss
- high drying rate
- low abrasiveness
- high temperature resistance
Being an innovation leader, we are of course continually discovering new optimization potential in our extraction and treatment processes, from which you can also benefit in your production. Speak to us about this. We’ll be glad to send you further information material or advise you about our products.
