If a design requires a high degree of accuracy, fine surface finish or defect free surface it reduces the castability of the part. [2] However, the casting process can be very economical for part designs that require intricate contoured surfaces, thickness variations, and internal features. [3]
The exact process and pattern equipment is always determined by the order quantities and the casting design. Sand casting can produce as little as one part, or as many as a million copies. Although additive manufacturing modalities such as SLS or SLM have potential to replace casting for some production situations, casting is still far from
Molten metal before casting Casting iron in a sand mold. In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a three-dimensional negative image) of the intended shape.
AutoCAST uses geometric reasoning for automating the design of casting methods elements – cores, mold cavity layout, feeders, feed aids and gating channels. Fast and intelligent simulation technology is employed to visualize mold filling and casting solidification in near-real time.
This technology allows engineers to predict and visualize the flow of molten metal, crystallization patterns, and potential defects in the casting before the start of the actual production process. By simulating the casting process, manufacturers can optimize mold design, reduce material consumption, and improve the quality of the final product.
Cast iron casting. Casting is a manufacturing process in which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process.

Evaporative-pattern casting is a type of casting process that uses a pattern made from a material that will evaporate when the molten metal is poured into the molding cavity. The most common evaporative-pattern material used is polystyrene foam. [1] The two major evaporative-pattern casting processes are: [1] Lost-foam casting; Full-mold casting
