Title:
MOLDING DIE, METHOD FOR MOLDING CERAMIC MATERIAL AND METHOD FOR PRODUCING CERAMIC ARTICLE
Document Type and Number:
Japanese Patent JP2021187156
Kind Code:
A
Abstract:
To provide a method for molding a ceramic material with high shape precision that can suppress cracking and deformation upon demolding and allows demolding by more simple operation and a method for producing a ceramic article having reduced burrs.SOLUTION: A method for molding a ceramic material comprises a raw material mixing step (S1) where ceramic powder, a resin a hardener and a solvent are mixed to obtain a casting liquid to be a ceramic material, a casting liquid injection step (S2) where the casting liquid is injected into a cavity 10 of a water-soluble molding die 1 formed with a water-soluble polymer material, a hardening step (S3) where the resin in the casting liquid injected into the water-soluble molding die 1 is hardened into a hardened body having a desired shape and a demolding step (S4) where the hardened body is demolded from the water-soluble molding die 1.SELECTED DRAWING: Figure 1B
