Casting

Casting is a manufacturing process in which molten metal, is poured into a specially designed mould and then allowed to solidify. The solidified part is known as casting. After solidification, the workpiece is then removed from the die to undergo different finishing treatments processes or for use as a final product. Casting methods are typically used to create very complicated or detailed solid shapes, heavy equipment and cast products are wildly used in different applications, including automotive components, aerospace parts, electronics, mechanical devices, and construction supplies.

Different types of casting and the casting process

Sand Casting
Sand casting basically relies on synthetic or naturally-bonded sand. Sand casting generally consist of finely ground grains with a smooth molding surface. The molten metal is poured into the mold cavity with the shape for the required part already shaped by synthetic or naturally-bonded sand, the sand can be also enhanced with addition of clay which strengthens and help the particles bond closely. Parts made from sand casting usually have rough surfaces with impurities. Sand casting is normally used for production of large parts.
Die Casting
Die casting method, molten metals are injected into the designed mold with high pressure which ensures the parts have better surface finish and high dimensional accuracy which makes some parts need little or no machining after the casting process. The mold is coated with lubricant before the molten metal is been injected into it. This lubricant helps to regulate the die temperature and to assist with ejection after solidification. Die casting has a relative high tooling cost, which makes it best when dealing with high volume products.
Investment Casting
This method of casting is mostly used in the production of parts used in aerospace, automotive industries. Investment casting uses a disposable wax for each cast part, the wax is applied before casting. Molten metal is then poured into the mold and allowed to solidify and set into the designed shape. The solidified part is then ejected, and the wax melted out of the solidified part for reuse. Investment casting usually has a high-quality surface and detail which reduces machining and tooling cost of parts. Investment casting is usually more expensive than the other casting methods
