工程数に応じた積層数のセラミック成形体が得られる。Figure 2 shows the process of press-molding ceramic raw material powder into a molded body.
The ceramic raw material powder C1 exhibiting a predetermined color is filled inside, and the raw ceramic molded body Ca shown in FIG. As shown in the same figure (c), ceramic raw material powder C2 exhibiting a color different from that of the ceramic molded body Ca was filled into the chamber U, and the upper and lower bunches p, p2 were used as shown in the same figure (d). Thus, a molded body in which raw ceramic molded bodies Ca + Cb are laminated is obtained. By repeating such steps, a ceramic molded body having the number of laminated layers corresponding to the number of repeated steps can be obtained.
