Production of Single Cylinder Engine Piston through Vacuum Die Casting in Sedi Enugu.

This research work looked into the fundamental properties of molten metal as well as the casting processes, especially the principle of operation of vacuum die casting used in the production of single cylinder engine piston.In addition, the factors that lead to the selection of vacuum die casting method for the project were enumerated. The main structure and working principles of vacuum die casting machine was explained. Furthermore, this paper treated mould design and mould materials requirement. And in conclusion, this paper discussed the alloy design of aluminum alloys used in the production of the piston. Although all the tests have not been carried out on components to ascertain their strength and durability but a functional test has been carried out by coupling the component on an engine and test running same for a while.
