ABSTRACT:
A mould set for injection moulding of plastics material comprises two one-piece components which together define the mould cavity and which are each produced by extrusion of high duty aluminum alloy so as to comprise, also, and integrally with each of them, all the necessary fixtures and fittings for the mould set. In addition, one of the mould components is provided with integrally extruded flanges enabling an ejector plate (also extruded from high duty aluminum alloy) to be supported without the need for complex fixtures. There is thus provided a mould set which performs the same functions as a conventional set even though the latter has three times as many components.
