R.Ganesh Narayanan, IITG Metal casting processes • Casting is one of the oldest manufacturing process. It is the first step in making most of the products. • Steps: - Making mould cavity - Material is first liquefied by properly heating it in a suitable furnace.
Sand casting is now and has been for some time one of the most commonly used manufacturing processes and the use of gray cast iron fits very well with this process. The reasons for choosing sand casting as the manufacturing process and gray cast iron as the alloy will be discussed further in the report. Problem Statement:
At present, this is the most common method of moulding of bricks in most countries. In this process a piece of land (the ground) is first cleaned, then thoroughly leveled and often made smooth by plastering. Some sand is sprinkled uniformly over it to make it non-sticky. There are two variations of ground moulding.

While this process is simple, the dimensional accuracy is low. Another type of binder process is called the hot-box process, which uses a thermoset and catalyst for a binder. The sand with the binder is packed into a core box that is heated to approximately 230 °C (446 °F) (which is where the name originated from).
