green sand in foundry

The process we use to create metal objects by pouring hot, molten metal into a mold is called foundry casting. The sand used to form the mold is central to the process. However, the previous generation of foundry sand uses silica sand, which causes environmental problems. Nowadays, there is a superior option known as green sand.

Green sand (moulding sand) consists of sand, clay, and water mixture. The clay is very important — it binds the sand together, so that the mold is strong enough to hold the melted metal without breaking due to the heat. Not only is this alternative more Earth-friendly, but it is also easier to deploy and produces superior metal objects.

Environmentally-friendly molding with green sand

The best things about green sand is it is environmental friendly. Old foundry sand (OFS) often contains toxic contaminants that can harm the environment and the humans who handle it. But green sand is composed of natural materials that are safe for the planet and not dangerous to workers. Green sand allows foundries to protect the environment and create a safer environment for your workers.
