发明名称 Multilayered preform and method of manufacturing it
摘要 The method involves supplying a co-extruded multilayer dose to a cavity of a mold (5). The multilayer dose is compressed only on part of its surface in order to form an object, where the compression direction is parallel to an axis of symmetry of the dose. A body, rotating around an axis of symmetry, is formed by the dose, where the dose consists of a radial stack of layers including a thin functional resin layer (3).
