セラミックス射出成形生産システムの最適化

抄録

The ceramic injection molding production system consists of a number of independent elementary processes. In the present study, the processing factors were taken up from four independent elementary processes and a statistically designed experiment using an orthogonal array was conducted. Thus the processing conditions under which the dispersion of the whole production system becomes the smallest were identified. The minimum dispersion conditions so identified were verified through a follow-up confirmation experiment. The material under investigation was sintered alumina. As a result, we reduced the variance of the dimensions of sintered molded products to one tenth of its original value.
