What are Green Sand Castings?

The green sand for the casting molds usually has a mixture of: Sand = 75-85%. Bentonite Clay = 5-11%. Water = 2-4%. Other materials = 3-5%. Silica in the sand can become airborne in the process of casting so American foundries install air control systems that pull the silica particles and anything else out of the air to keep foundry workers safe.

Die Casting vs Sand Casting

Mar 03, 2021In sand casting, the liquid metal is poured directly into a mold in the sand and there is no high pressure involved. When the metal has cooled, the mold is opened and sand brushed away form the product. But there is more downtime to this procedure as sand needs to be replaced around the match plate after each casting.
