INTEGRATED CASTING CORE-SHELL STRUCTURE FOR MAKING CAST COMPONENT WITH NON-LINEAR HOLES

The present disclosure generally relates to integrated core-shell investment casting molds that provide filament structures corresponding to cooling hole patterns in the surface of the turbine blade or stator vane, which provide a leaching pathway for the core portion after metal casting. These fila...

Zusammenfassung:	The present disclosure generally relates to integrated core-shell investment casting molds that provide filament structures corresponding to cooling hole patterns in the surface of the turbine blade or stator vane, which provide a leaching pathway for the core portion after metal casting. These filament structures may be linear or non-linear. The invention also relates to core filaments that can be used to supplement the leaching pathway, for example in a core tip portion of the mold.
