Ceramic Injection Molding(CIM) is suitable for manufacturing complex shape products. However, considerable distortion occurs in de-waxing stage. It is caused by the visco-elastic deformation, due to the release of the latent strain, which is generated in the material during injection molding stage. In this paper, injection molding into T-shaped cavity has been dealt with and distortion in de-waxing stage is examined. Then, the distortion property is discussed in consideration with visco-elastic property of material.
