This paper demonstrates the possibility of designing and developing a four-cavity low pressure die casting mould in SEDI-Enugu. This research and development included the design of the die blocks and the core box for core production. Furthermore, the die blocks were cast, machined and later heat treated to obtain the desired properties of a mould material. After which the components were assembled and mounted on the Low pressure die casting machine. Emphasis was made on the coating of the mould and crucible pot internal surfaces with a solution of zinc oxide and sodium silicate. This is done prevent iron entrapment in mass of the molten metal as well as to minimize the sticking of castings on the mould during casting operation.
