Description
DANSAND® Foundry Sand is developed for castings of liquid metals in various compositions. Silica sand for foundry must have a high quartz content, must be well defined and it must be as dust-free as possible. At Dansand®, we have developed a process in which the sand is first washed and hydro-classified, then oven-dried using natural gas and finally sifted to standard sortings. The purpose of the process is to achieve high sintering temperatures, high chemical purity and a low slurry content – a process that ensures you a good and safe casting of the different types of goods.
We offer four standard grades, and we are also capable of supplying special grades per request.
Benefits of Dansand foundry sand
- High silica content
- Well-defined grain curves
- Low dust content
- Low slurry content
- High chemical purity
- High sintering temperatures
