Abstract

The method involves first arranging a hollow core element in a mould. Then mould is then closed and the hollow chamber around the element is loaded with a material which is hardened by heating the mould to a given temperature. The hollow core element is heated to another temperature before the mould is heated. The core element is heated by circulating a hot gas through it.
