Casting Process: Advantages and Limitations

Casting process

Casting is also known as foundering, is the oldest manufacturing process in which liquid molten metal is poured into a perforated casting cavity of refractory material. Allow liquid metal to solidify, after solidification the casting metal can be taken out by breaking the mold. The casting process is used to produce components such as pistons, mill rolls, wheels, cylinder blocks, liners, machine tool beds.

Casting process

Different terminology used in casting process are molding sand, baking sand, facing sand, loam sand, parting sand, CO2 sand, flak, pattern, parting line, sprue, runner, ingate, riser, chill, and chaplets.

Molding sand:
Molding sand is the refractory material used for making the mold. It is a mixture of silica, clay, and moisture to get required properties.

Baking sand:
Baking sand consists of refractory material, and it is made of used sand or burnt sand.

Facing sand:
Facing sand is the carbonaceous material sprinkled on the inner surfaces of the molding cavity for obtaining better surface finish.
