Method for producing a ceramic core

Abstract

The invention relates to the field of casting, and more particularly to a method of producing a ceramic core (1) for casting, said core (1) presenting a shape that includes at least a first lateral protuberance (11), and the method comprising at least a step of injecting a paste comprising a ceramic granulate and a polymer binder into a mold cavity In order to form a part (10) presenting a shape corresponding to the shape of the core (1) together with at least one additional lateral protuberance (15) adjacent to said first lateral protuberance (11), a step of firing the part (10), and a step of eliminating said additional lateral protuberance (15) from the part (10) after said firing step.
