May 03, 2010Sand, when mixed with the correct ratio of sodium silicate, rammed into a core box, and then exposed to carbon dioxide (CO 2), will result in a very hard and durable sand core.Never having used sodium silicate (and never having made sand cores before!), this was an excellent lesson in learning what works and what doesn't.
I needed learn how to make Green Sand for metal casting. If you watched the furnace video you saw me making refractory, and making green sand is about the same process. Simply put, it is a mixture of sand, bentonite clay, and a bit of water. Using this kind of sand is called green sand casting.

Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term sand casting can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries.Over 60% of all metal castings are produced via sand casting process.

The Nobake Process Nobake is a casting process that involves the use of chemical binders to bond the molding sand. Sand is conveyed to the mold fill station in preparation for filling of the mold. A mixer is used to blend the sand with the chemical binder and catalyst. As the sand exits the mixer, the binder begins the chemical process of hardening.
