Abstract

A method for the simultaneous co-injection of at least two materials in the fluid state into a mould, kept separate and heated until at least one injection nozzle 6 is reached, comprises injection by means of the simultaneous expulsion of the materials from said nozzle 6, said materials coming into contact before coming out of an outlet 27 in a nozzle 6 without interacting before coming out of their respective feed channels 21, 24 to said outlet. The method is actuated with a simultaneous co-injection device comprising at least one nozzle 6 with a tubular part 26 containing an external sleeve 17 provided with its own expulsion opening, to which a first fluid material arrives, and a part 24 surrounding said sleeve 17 to which the second material arrives, said parts 26, 24 opening in the abovementioned tubular part 26 in such a way as to send the two materials into it so as to permit the joint expulsion of the same. <IMAGE>
