Sand Casting

Sand casting, the most widely used casting process, utilizes expendable sand molds to form complex metal parts that can be made of nearly any alloy. Because the sand mold must be destroyed in order to remove the part, called the casting, sand casting typically has a low production rate. Due to relatively low tooling costs the casting method can be used for prototype manufacturing. The surface finish and casting tolerances are adequate for most purposes.

 

Feature:

Sand casting is chosen for the production of small numbers of castings, for complex shape castings requiring intricate cores, or for large castings. Advantages include low tooling costs, largest casting dimensions achievable,

wide variety of metals and alloys (ferrous and non-ferrous) may be cast (including high melting point metals),very low gas porosity is possible, and general versatility of the process is good.

Dimensions: Max. 2.450 x 2.000 x 1.450 mm.
