PURPOSE: A method for manufacturing moldings with an electromagnetic wave shielding function is provided to absorb the electromagnetic wave of electronic products by forming a magnetism using the magnetic material of the molding. CONSTITUTION: A method for manufacturing moldings with an electromagnetic wave shielding function comprises following steps. Mixture is formed by mixing grand purpose polystylene 78wt.%, high impact polystyrene 20wt.%, foaming agent 0.5wt.%, plasticizer 0.6wt.%, release agent 0.5wt.%, and stabilizer 0.5wt.% The mixture is plasticized and mixed at the temperature of 150~170°C. The plasticized mixture is extruded so that molding is formed in the molder. The molding is frozen in the water. The molding passes through the molder and cubic design is formed. The color is transferred to the molding and the mixed solution is automatically applied and dried in the molding.
