Abstract (en)

[origin: EP1813365A1] The production of orifices (110) for the evacuation of cooling fluid in the wall (171) of a component fabricated by the lost wax foundry process with the formation of a wax model in a mould, the orifices incorporating a first portion (110E) emerging at the surface of the external wall (171ext), consists of: (A) making cavities in the wax model corresponding to the first portion of an orifice; (B) then machining in the component coming from the foundry of a second portion (110T) of an orifice, connecting the bottom of the first portion with the internal surface of the wall. An independent claim is also included for a turbine component obtained using this method.
