THE HANDBOOK SAND CASTING BY COW, AMMEN TAB BOOKS BLUE RIDGE SUMMIT, PA. 17214
Green Sand Green sand casting uses a kind of humid sand mixed with black clay. This sand is cheap, and can be used repeatedly. So, it is suitable for manual molding, machine molding and automated machine molding. Green sand is the cheapest sand casting process, and is also mostly used casting process in China.
Green Sand Molding The most common method used to make metal castings is green sand molding. In this process, granular refractory sand is coated with a mixture of bentonite clay, water and, in some cases, other additives (Fig. 1). The additives help to harden and hold the mold shape to withstand the pres-sures of the molten metal.

Sand casting is able to make use of almost any alloy. An advantage of sand casting is the ability to cast materials with high melting temperatures, including steel, nickel, and titanium. The four most common materials that are used in sand casting are shown below, along with their melting temperatures.
Sir Gawain and the Green Knight is a romance par excellence––though few English examples of the genre before Spenser are as sophisticated and witty as Sir Gawain, which explores how difficult it is for a knight to reconcile the competing codes of chivalry, courtly love, and Christianity.
Foundry shop is the place where the metal casting is prepared by melting and pouring the molten metal into moulds. Some of the commonly used tools in foundry shop for moulding process are showel, trowel, riddle, rammer, draw spike, swab, vent wire and slick tool..

Granular soils range in particle size from .003" to .08" (sand) and .08" to 1.0" (fine to medium gravel). Granular soils are known for their water-draining properties. Characteristics Sand and gravel obtain maximum density in either a fully dry or saturated state. Testing curves are relatively flat so density can be

Green sand casting: Type of sand casting characterized by the use of a wet sand mixture to create a mold. Dry sand molds are limited in the amount of weight they can support; green sand molds can support a much higher mass. In addition to water, bentonite, clay, and anthracite are normal components of green sand mixtures. Heat treatment:

reclaimable, with between 90 and 95% of the sand being recycled, although new sand and additions are required to make up for the discarded loss. These features, combined with the relative ease of mold production, have ensured that the green sand molding process has remained as the principal method by which castings are produced. THE SAND
Sep 03, 2004 · This seems a practical suggestion: after all, clay is the finest-textured soil and sand the coarsest, so mixing the two should result in just the right blend. It’s not that simple, though. The problem is that you must add a great deal of sand to make a difference–at least 4 inches of coarse sand to the top 6 inches of clay soil.

The plaster follower plate can be used to make green sand or no-bake sand molds. In this case the pattern is held by the plaster while the first half of the sand mold is rammed up. Then the mold is turned over, the backing plate removed and the second half of the sand mold created. The sand stays in the mold box so it is now a "flask".
