High pressure die casting is the best suitable method for the manufacturing of Heavy Vehicle Engine Components. The design of feed system was done by Pro E wildfire 4.0 and the movement of molten metal inside the cavity was analyzed using the Magma software for an injection pressure of 600 kgf/cm2.The die for the Heavy Vehicle Engine Components was designed and manufactured. The engine components were manufactured with the help of 250 T locking force capacity high pressure die casting machine. The radiographic inspections for some of the sample components were carried. The hardness of the Heavy Vehicle Engine Components and the porosity levels were evaluated. The component’s dimensions were checked by a co-ordinate measuring machine.
