Abstract: PROBLEM TO BE SOLVED: To provide a lost pattern casting method by which a casting having an excellent quality without developing residual defects and burnt defects can be obtained. SOLUTION: When a product is cast with poured molten metal by pouring the molten metal into a mold prepared by embedding a pattern with a facing mold formed therein in the molding sand and melting away the pattern, an exhausting passage provided with an exhaust gas restraining means for exhausting a gas generated by melting away the above pattern to the outside of the mold is arranged independent of the facing mold, and the ratio of the permeability of the facing mold to the thickness (mm) of the facing mold is made to be ≤0.1 in the permeability/thickness.

Abstract: PROBLEM TO BE SOLVED: To provide molding sand composition excellent in fluidity. SOLUTION: This molding sand composition contains a refractory granular aggregates and non-hollow spherical fine grains. In the case of defining ϕ as average grain diameter of the refractory granular aggregates, the average grain diameter of the non-hollow spherical fine grains is ϕ/8-ϕ/5,000. Concretely, it is desirable that the average diameter of the non-hollow spherical fine grains is 0.1-50 μm. Further, it is desirable that a binder, such as a furan resin, a water-soluble alkaline phenol resin, is contained in the molding sand composition, because the fluidity of the molding sand composition containing the binder is easily lowered. As the non-hollow spherical fine grain, silica fine grain, silicone resin fine grain, polyethylene fine grain, etc., are used, and the silica fine grain, in which silicon treatment is applied on this surface, is suitably used. Blending ratio of the non-hollow spherical fine grain is desirable to be 0.01-1.0 pts.mass to 100 pts.mass of the refractory granular aggregate.
