What is foundry sand? - Solex
The green sand is reclaimed by a thermal process that requires cooling the sand before it can be reintroduced into the casting process. The majority of foundries use green sand casting in their process method. No bake casting is another popular method used to produce "core molds" or smaller volumes of complex castings for both ferrous and non-ferrous metals. This method applies a chemical ...
What is foundry sand? - Solex Thermal Sciences
As foundry sand is an integral part of the casting process, using sand that is too hot or too cold leads to reduced casting quality, with lasting negative affects along the entire production line. When the molten metal is poured into a mold with green sand that is too hot, it can result in higher scrap rates as well as more consumption of bentonite. No bake sand that is too hot or too cold ...
