Various fine, precise parts of ceramics are made by injection molding in electronics industry. However, many kinds of defects occur in injection molding, de-waxing, and sintering stages. Their causes have not been made clear yet. Recently, production leading time reducement is urgent problem and estimation of molding defect occurrence in mold deseigning stage is very important. In this paper, three problems are discussed from this aspect. (1) Precise viscosity measuring method in consideration with slippage at capillary wall is developed, which contributes to improvement of simulation accuracy of melt flow. (2) Method of measuring welding defect generation criterion is developed. (3) Occurence of considerably large distortion at initial stage of de-waxing is pointed out and an in-plane shearing method of a sheet specimen for measuring visco-elastic property is proposed, which is necessary for estimation of the distortion.
