Summary:The invention relates to the field of casting and more particularly to a method for producing a ceramic core (1) for casting, said core (1) having a shape that has at least one first lateral protrusion (11), the method involving at least a step of injecting a paste containing a ceramic granulate and a polymer binder into a mould cavity to form a component (10) having a shape corresponding to the shape of the core (1) with the addition of at least one additional lateral protrusion (15) adjacent to said first lateral protrusion (11), a step of curing the component (10) and a step of eliminating the said additional lateral protrusion (15) from the component (10) after said firing step. 本发明涉及铸造领域，更具体地涉及种用于制造用于铸造的陶瓷芯的方法，所述芯(1)的形状具有至少个第侧向突起(11)，该方法至少包括将包含陶瓷颗粒和聚合物粘合剂的浆料注入模腔中以与邻近于所述第侧向突起(11)的至少个附加的侧向突起(15)起形成其形状与芯(1)的形状对应的零件(10)的步骤，固化零件(10)的步骤以及在所述烧制步骤后从零件(10)中去除所述附加的侧向突起(15)的步骤。
