The invention relates to a method for producing crowns etc. by producing a frame, for example, made of alumina, whereby a film (6) is shrink-fitted on the die (3) of a working model. The film (6) is provided with a slip and the slip is baked on a frame after the film is removed. In order to accelerate the method and to avoid the loss of materials, the die (3) is placed on a rotatable shaft (2). The slip is deposited with a tool (5). A drying process using a hot air dryer (7) is carried out during and/or after depositing the slip. This method can also be carried out in a CNC machine with which the veneer ceramic is successively deposited. A separating agent similar to lipstick can be deposited in place of the film (6). Said separating agent melts at temperatures greater than 45 DEG C when the spacer function is not used. The invention also relates to a crease-free shrink-fitting of the film (6). In addition, the invention shows how the infiltration itself can result in the ceramic furnace, whereby the frame lies on a base which absorbs the excess glass. The invention also relates to a dosing device for slip with which the slip is to be dosed on the shrink-fitted film in a uniform consistency. |
