The machine comprises an annular cavity for receiving a silicone material. The material is injected in a cold state via a coldrun nozzle (20) and cured by heat in the cavity. The cavity has a narrow cross-sectional area over a substantial portion of the cavity and the cavity is connected to a venting area (13) . The cavity has an annular enlarged portion (18) at the proximal portion of the cavity, arranged adjacent said inlet (24) and a groove (14) at the distal portion of the cavity. The narrow cross-sectional area has a decreasing radial dimension towards the distal portion of the cavity. The surface of the cavity is grit blasted. |
