Method for casting components with localised reinforcement, such as a bimetallic piston, characterised by successive castings in the same mould of two separate alloys, by means of a vertical moulding and of two alloys, in which the solidification intervals are compatible, that is to say the temperature of the start of solidification of the second alloy fits into the interval of solidification of the first alloy, on the one hand, and in which an appropriate quantity of the first alloy is solidified at the temperature of the start of solidification of the second alloy, on the other hand. Application, in particular, to bimetallic pistons for internal combustion engines. <IMAGE>
