The Manufacturing Process The preparation of sand consists of five basic processes: natural decomposition, extraction, sorting, washing, and in some cases crushing. The first process, natural decomposition, usually takes millions of years. The other processes take considerably less time.

Sand: Sand: Product of the disintegration of rocks over long periods of time. Most sand casting operations use silica sand (SiO 2). A great advantage of sand in manufacturing applications is that sand is inexpensive. Another advantage of sand to manufacture products by metal casting processes, is that sand is very resistant to elevated

The No-Bake Sand casting process involves creating a mold using sand and resin. Sand is packed around a pattern that contains the imprint of the casting to create a cope (top half of sand mold) and drag (bottom half of sand mold). Molten metal is poured into the sand mold, through the runner and gating system and allowed to cool and solidify.
