In the foundry industry, silica sands are traditionally used as moulding material to manufacture moulds and cores. The requirements for the quality and precision of foundry products have risen sharply in recent decades.
The most important feature of foundry sand is the high SiO2 content, between 94 and > 99%. Our silica sand reaches values of > 99%.
The advantages of our silica sand are its high purity, high sintering temperature of > 1600 °C and its high SiO2 content.
Our products arise from previously screened grain fractions, so they can be offered in line with the requirements and customer wishes.
Another benefit of our products is the low clay and sludge content, which is achieved by processing in the sand washers.
