The invention relates to a method of producing a multilayer object that forms a rotating body, said object comprising at least a base having a diameter D, which is connected to a side wall having an average thickness E and a height H. The inventive method consists in supplying a coextruded multilayer dose to the cavity of a mould and subsequently compressing the dose in order to form the object, said dose forming a body that rotates around an axis of symmetry. The dose consists of a radial stack of several layers including at least one thin functional layer, the outside diameter of said dose being essentially equal to D. In addition, the compression direction is parallel to the axis of symmetry of the dose and the compression is performed on a face of the dose. The method is characterised in that the dose is compressed only on part of said face. |
