The invention relates to a process for injection molding articles having a number of layers of different plastic materials that are sequentially and/or coaxially injected, in plasticized form, into a mould. Prior to injection, the different plastic materials are brought into a hollow chamber in a preselected order and amounts, with the aid of separate injection units or by means of a distributor, which is made of elementary modules, each of which is capable of creating a certain combination and configuration of plastic materials in the chamber. The contents of the chamber are then injected into the mould.
