Casting is the one of the oldest manufacturing processes, and even today is the first step in manufacturing most product. In this process the material is first liquefied by proper heating and then this liquefied is poured into a previously prepared
The casting of steel presents a number of special problems due mainly to the high casting temperature, typically 1550–1600ºC, and the volume shrinkage that occurs on freezing. Steel castings are often used in critical situations where optimum mechanical properties are essential so that freedom from casting defects is particularly important.

The sand mould casting process is used in this report. The casting process is used for making small to large cast parts, complicated shapes, and precision parts, etc. Making a casting without defects is an important requirement for its strength. The effective and efficient design of the gating system is necessary for making defects free castings.
casting profiled to minimize stress concentration. Cast Iron: The Natural Composite Iron castings, as objects of art, weapons of war, or in more utilitarian forms, have been produced for more than 2000 years. As a commercial process, the production of iron castings probably has no equal for longevity, success or impact on our society.

In specific cases, the casting section can be strewn with blowholes of pinholes. The interior walls of blowholes and pinholes can be shiny, more or less oxidized or, in the case of cast iron, can be covered with a thin layer of graphite. The defect can appear in all regions of the casting. Possible Causes
analyse the defects found in castings. HOT TEAR DEFECTS Hot tear is a defect that occurs during solidification of a casting. Though steel is poured at high temperature, this temperature is low relative to high freezing temperature range for steel. The result of this is that steel starts freezing soon after being poured, often before the moulds
