When should you choose sand casting?

Sand casting is an economical process for creating rough metal parts. Raw castings are then machined to produce finished products or components. Sand casting is the least expensive of all casting processes, including die and investment casting. Sand casting may require a longer lead time for production at high output rates (1–20 pieces/hour/mold), but is unsurpassed for large-part production. Sand has almost no upper limit on part weight and minimum part weight ranges from 0.075–0.1 kg. The sand is bonded together using clays or chemical binders. In most operations, the sand can be recycled many times, requiring the addition of only small amounts of sand each time.

Preparation of the sand mold is fast but requires a pattern that can "stamp" out the casting template. Typically, sand casting is used for processing low-temperature metals, such as iron, copper,aluminum, magnesium, and nickel alloys. It can also be used for hightemperature metals where other means would be impractical. Sand casting is by far the oldest and best understood of all techniques. As such, automation can easily be adapted to the production process, although somewhat less easily to the design and preparation of forms.

Thus, sand casting is a ideal casting process when you have a design for below requirements:

• Low tooling costs

• Low or high volume requirements

• Low part cost

• Quick delivery or turn around
