Sand casting, while nowhere near as precise as investment casting, is a low-cost, low complexity manufacturing process that has repeatedly proven itself as an integral part of modern manufacturing. If investment casting is too cumbersome, or if large parts are needed, consider implementing sand casting into your production line.

Note: There are two types of sand used in the casting process that are green sand & dry sand. Greensand is a mixture of silica sand, clay, other additives & moisture. Whereas dry clay is the mixture of sand & fast curing adhesive. After the sand sets, we will reserve the drag as the pattern pointing upward. Now we will remove the pattern.

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.
