Sand Casting
Sand casting is a metal casting process that uses expendable sand molds to manufacture components across a wide range of sizes and geometries. It is commonly used for pump housings, machine bases, valve bodies, industrial equipment, and complex metal parts where casting flexibility and material versatility are important.

Manufacturing overview
Sand casting involves forming a mold cavity using compacted or bonded sand, introducing molten metal, and allowing it to solidify.
The process is suitable for prototype, low-volume, and production applications depending on tooling and casting complexity.
Common materials include cast iron, ductile iron, carbon steel, alloy steel, aluminum, and selected copper alloys.
Typical applications include machinery housings, pump bodies, structural castings, industrial frames, and heavy equipment components.
Sand casting offers flexibility for large components and complex internal cavities through the use of cores.
Design considerations include wall thickness, draft angles, shrinkage allowance, gating, risers, and machining stock.
Casting surface finish and dimensional accuracy depend on mold preparation, alloy, component size, and process control.
Critical machined surfaces, bores, and threaded features generally require secondary machining.
Buyers should provide a 3D model, dimensioned drawing, material grade, quantity, casting tolerances, machining requirements, and inspection criteria.
Quality requirements may include chemical analysis, mechanical testing, dimensional inspection, and nondestructive testing where applicable.
