Manufacturing industries are still in the phase of improving the accuracy in order to improve the quality of a component or product. In this review paper in order to solve this industrial problem we are going to make a study based on vacuum pressure casting for the manufacturing of complex shaped components and also studied the manufacturing of sheet metal using pressure casting method instead of forming method. Vacuum pressure casting will meet the requirement of industries in the case of achieving high accuracy with complex and thin wall body parts. In this method there is no temperature loss during the transfer of the molten metal into the casting machine and because of this the defect like porosity can be solved. In this paper we are investigating the microstructure, porosity, surface roughness and mechanical properties of the component developed using vacuum pressure casting in comparison with gravity casting
