Abstract
The invention relates to a method of manufacturing a multilayer object in synthetic resin () by compression molding a dose of molten multilayer resin () comprising at least one functional layer (), each layer of the dose being in the molten state at the time of compression; the method consisting at least in co-extruding the resins through a die, in cutting the extrudate periodically in order to obtain a dose (), then in depositing the dose () in the molten state in the cavity of a mold; the method thereby defining, within the dose, an extrusion direction and an arrangement of the functional layer () parallel to the extrusion direction; the method being characterized in that the dose is compressed along a compression axis () which intersects the extrusion direction, so as to introduce, into the flow of the layers, asymmetry with respect to the compression axis (). The invention also relates to an object obtained with the aforementioned method, to a dose used in the context of this method and to a device for implementing the said method.
