A method of producing minute three-dimensional components by casting was experimentally examined. In the transcription of minute shapes, the particle size of the mold material and the production method of the mold are problematic. In particular, handling of minute models and casted products is extremely difficult. Molds were prepared by the following method. First, a model to be burnt was immersed in slurry. After the slurry density was increased by the application of centrifugal force, the binder was solidified to obtain a raw mold. A mold was then obtained by burning and removing the model material through firing the raw mold. The obtained mold was immersed in a hot solution for the casting process. With immersing the mold in water, the mold underwent self-breaking and the casted product could be removed without damage or cracking. It is confirmed that the accuracy of transcription of the casted product is approximately 10 μm.
