Abstract
A molding apparatus for producing a ceramic molding comprising a material-flowing path, a molding die disposed at one end of the material-flowing path, and a pressurizing means for extrusion-molding the molding material; the material-flowing path comprising pluralities of porous plates for passing the molding material and a screen fixed therebetween, and a method for producing a ceramic molding using this apparatus.
Claims15
A method for producing a ceramic molding using a molding apparatus comprising a material-flowing path and a molding die disposed at one end of said material-flowing path, comprising extrusion-molding a molding material charged into said material-flowing path from said molding die, through pluralities of porous plates and a screen fixed therebetween in said material-flowing path, wherein said pluralities of porous plates are disposed in the material-flowing path such that the pores of the porous plates on opposite sides of the screen are substantially aligned with respect to center axes.
The method for producing a ceramic molding according to clam 1, wherein pluralities of said porous plates have a pore diameter 1/10 or less of the inner diameter of said material-flowing path, and an opening area ratio 50% or more of the cross section area of said material-flowing path.
A method for producing a ceramic molding using a molding apparatus comprising a material-flowing path and a molding die disposed at one end of said material-flowing path, comprising extrusion-molding a molding material charged into said material-flowing path from said molding die, through pluralities of porous plates and pluralities of laminated screens fixed therebetween in said material-flowing path, wherein said pluralities of porous plates are disposed in the material-flowing path such that the pores of the porous plates on opposite sides of the laminated screens are substantially aligned with respect to center axes.
A molding apparatus comprising a material-flowing path, a molding die disposed at one end of said material-flowing path, and a pressurizing means for extrusion-molding said molding material;
- said material-flowing path comprising pluralities of porous plates for passing said molding material and a screen fixed therebetween, wherein said pluralities of porous plates are disposed in the material-flowing path such that the pores of the porous plates on opposite sides of the screen are substantially aligned with respect to center axes.
A molding apparatus comprising a material-flowing path, a molding die disposed at one end of said material-flowing path, and a pressurizing means for extrusion-molding said molding material;
- said material-flowing path comprising pluralities of porous plates for passing said molding material and pluralities of laminated screens fixed therebetween, wherein said pluralities of porous plates are disposed in the material-flowing path such that the pores of the porous plates on opposite sides of the laminated screens are substantially aligned with respect to center axes.
