Abstract: A novel manufacturing process of mold containing continuous holes and used for filter materials, gas dispersive materials, and mold materials. By this invention, the epoxy resin mixture including an epoxy compound having one or more epoxy groups in each mole, a hardener which reacts with and hardens the epoxy compound, emulsifiers, water or water-surface active agent, and fillers respectively is used as the molding material. As the emulsifier, at least two kinds of three different kinds of nonionic emulsifiers of 4-8, 8-17, and 11-15.6 HLB respectively are used together.The molding material is cured to a desired shape to prepare a mold containing continuous holes and for molding, conventional methods such as hardening after casting, for example, are adopted.

Abstract: The first invention relates to a novel manufacturing process of mold containing continuous holes and used for filter materials, gas dispersive materials, and mold materials. By this invention, the epoxy resin mixture including an epoxy compound having one or more epoxy groups in each molecule, a hardener which reacts with and hardens the epoxy compound, emulsifiers, water or water-surface active agent, and fillers respectively is used as the molding material. As the emulsifier, at least two kinds of three different kinds of nonionic emulsifiers of 4-8, 8-17, and 11-15.6 HLB respectively are used together. This is the primary feature of the invention and no molding materials including such emulsifiers are known so far. The molding material is cured to a desired shape to prepare a mold containing continuous holes and for molding, conventional methods such as hardening after casting, for example, are adopted.The second invention relates to a novel casting mold suitable be for slip discharge casting.
