Process for manufacturing insulating ceramic inserts which are used as sealed passages for electrical conductors through a metal wall, consisting in silk-screen printing a green-ceramic sheet using a conductive ink in patterns which are generally in the form of a ring, in pressing the patterns, in drilling holes in the centre of the ring and in at least one other green sheet, in laying and pressing the silk-screen-printed sheet against at least one, or between two, other green sheet, or sheets, by bringing the holes into coincidence, in making a cut around each hole, in metallizing the outer lateral surface of the component obtained, and in heat treating in order to fire and sinter, the sintering thus being able to be carried out before metallizing the outer lateral surface. <IMAGE> |
