ABSTRACT:
A mould assembly for producing multiple castings in which a plurality of mould components are closely arranged together in an array and define a plurality of mould cavities. At the base of the array there is provided a regularly shaped space which communicates with each of the individual mould cavities via a runner passage and thus molten metal admitted to the space fills each of the mould cavities simultaneously leading to uniform properties in all the castings. The individual mould components are preferably injected moulded in a ceramic material.
