Metal infiltration apparatus comprising a die assembly (1, 2) formed of two or more separable members having opposed surfaces which define between them a die chamber (5) capable of evacuation via outlet (7) and receiving molten metal via feed line (8), and at least one mould assembly (3, 4) comprising separable parts and locatable within said die chamber, the separable parts (3, 4) having surfaces which wholly or partially define between them a mould cavity (5a) which can receive a body (10) to be infiltrated and which is capable of fluid communication with said die chamber when located therein, evacuation means and molten metal supply means being provided such that the pressure within the, or each, mould cavity can be reduced and molten metal can reach the mould cavity, or each of them, to infiltrate a body when located therein. |
