Casting Process 

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 solidity.

In this process, complex parts can be manufactured economically and rapidly that otherwise would involve a lot of time if produced by other methods like shaping or cutting. Casting process can be utilized to produce a large variety of parts that are used in different industries.

The major casting processes used in our manufacturing are the following:
 

• ♦ Die Casting
•  

•  
• ♦ Investment Casting

Die casting - In this process metal is forced into the mold at a high pressure that ensures production of identical parts, a better surface finish, and an increased dimensional accuracy. Some parts produced by die casting even do not require machining after casting, or may require only a light machining to achieve the desired dimensions.
 

Sand casting is normally used for the production of large parts, by filling a molten metal into the mold cavity that has been shaped from natural or synthetic sand. Surface of the sand castings is normally rough with surface impurities for which a machining allowance is included.
 

Investment casting is a manufacturing process used for metals that are difficult to be machined or fabricated. This process provides an excellent dimensional accuracy and surface finish. The pattern is made of wax or other substance that is melted, leaving behind a cavity which is filled with the material of the part being produced.
