<p>A method and apparatus for shaping ceramic multi-layer structural bodies by extruding through a die. Ceramic layers (1,2) having different properties are fed under pressure, united and integrated in an extruding apparatus, while the thicknesses of the layers are controlled by adjusting extruding pressures. The extruding apparatus comprises a die (18) having a tip end opening of a given shape corresponding to the structural bodies to be extruded, a first extruding means (16) capable of feeding a ceramic molding compound to the die under a given pressure, and a second extruding means (17) for feeding another ceramic molding compound to the die. The second extruding means is provided separately from the first extruding means.</p> |
