Even the vapor vulcanization technology has developed a lot. The uneven temperature distribution caused by the condensation water inside the capsule still exists. In this paper, a numerical simulation study was conducted on vapor condensation of tyre capsule. Using a simplified two-dimensional model, after the 240s calculation, we analysed the result. The result shows that there was flow inside, and it was mainly induced by the condensation water flowing down the wall after it had been produced on the wall. The height of the condensed water layer is about 4.0mm. The volume of condensed water in three dimensions is about 240ml, which results in uneven temperature distribution. The temperature of the wall area with condensed water is about 3 to 13 lower than other wall areas, and the maximum °C°C temperature difference occurs at the deepest part of the condensate layer.
