PURPOSE:To enable cleaning of a die simply and efficiently, by performing molding by making use of a molding material consisting essentially of amino resin, a filling agent and epoxy resin and taking in a deposit on the surface facing on a cavity of the die. CONSTITUTION:A material consisting essentially of amino resin, filling agent and epoxy resin is constituted so that when the material is molded within a die, a deposit on the surface facing on a cavity of the same die is taken in a molded product. Since the amino resin possesses properties, which is apt to take the deposit in the molding material, and moreover a low cost, the same is suitable for cleaning. A combined matter of the same with the rubber becomes apt to take in the deposit on the mold by coupling holding properties of the amino resin with adhesion of the rubber. It is preferable to use an organic filling agent together with an inorganic filling agent as the filling agent. Those materials are made into the molding material by performing mixing, kneading and crushing of them and granulation at need. Molding is performed by putting the molding material into the cavity of the die. |
