One of the first steps in any manufacturing activity is the process of castings. Casting provides the initial workable material (in terms of geometry) for conventional and non conventional machining process.
Casting is the melting of any material by heating and then pouring it into a mold to form desired shape. Formally casting is defined as,” The process in which a molten metal flows by gravity or other force into a mold where it solidifies in the shape of the mold cavity”.
The solidified part formed as a result is termed as Casting.
Parts of any form and shape, however intricate they may be, can be formed using casting. However, casted parts do not have good quality surface finish and need to be machined and grinded.
There are three steps in metal casting:
- Melt the molten metal
- Pour the metal into the mold
- Let it freeze
In the coming articles we will discuss the method of casting in detail and will discuss different types of casting processes (conventional and non-conventional).
