Green sand molding remains an attractive casting production method for two main reasons: 1. Green sand production is and will always be less expensive, as the price of chemical binders continues to rise faster than normal inflation. 2. Green sand foundries are not as labor intensive.
Versatile: green sand can be molded to produce complex castings with extensive gating systems. Tougher: Withstands high temperature; the molds retain their shape when the molten metal is poured Greener: casting with green sand is a sustainable process; the sand is recovered and reprocessed after every casting cycle and the metal scraps are recycled in an endless loop.
1. Green sand moulding is the least expensive method of producing a mould. 2. There is less distortion than in dry sand moulds, because no baking is required. 3. Flasks are ready for reuse in minimum time. 4. Dimensional accuracy is good across the parting line. 5.

Green Diamond sand is technically an Olivine sand that has been processed by melting, then granulated by quenching in water. It has the same advantages as natural Olivine, which is no free silica and low thermal expansion. This minimizes, or eliminates expansion defects, and reacts basic, rather than acidic like silica sand.

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.
The room temperature sample remains black, the green sand tested at 572F (300C) has a gray color, and the sample tested at 1,292F (700C) appears light gray. When thermal erosion data is examined as compactability increases for the same level of clay in the green sand system, the percent green sand loss decreases at room temperature (Fig. 4).

In the green sand casting process, molds are made from a mixture of sand, clay, water, and carbonaceous additives (e.g. bituminous seacoal, anthracite, or ground coke). About 85% of the mold (EPA, 1998), by mass, is sand. The clay (4 to 10%) and water (2 to 5%) act as the binder system from which the mixture derives its strength.
