PRODUCTION OF MOLDED ARTICLES

摘要

PURPOSE:To prohibit the leakage of pulverized raw materials and provide the molded articles having excellent strength and quality at the time of preforming these raw materials in particular. CONSTITUTION:A temporary binder 34 reacts with the liquid additives 32 and dissolved layers 36 are obtd. when the liquid additives 32 and the temporary binder 34 are added to the spacings among respective powder and granular materials 30. The temporary binder 34 and the liquid additives 32 bond each other via the dissolved layers 36 and enclose the respective powder and granular materials 30, thereby expanding the apparent particle diameter A of the powder and granular materials 30. Then, the apparent particle diameter expands even if the powder and granular materials 30 themselves are fine particles. The leakage of the particles from mold clearances is thus effectively prohibited.
