Modern Investment casting method has been applied in industrial production in the twentieth century forties. At that time the development of jet engines, require manufacturers such as blades, impellers, nozzles and other complex shape, size, precision and smooth surface of the heat-resistant alloy parts.

As the heat-resistant alloy machining difficult, complex shape parts, which can not or difficult to use other methods of manufacture, therefore, needed to find a new precision in the molding process, so learn the ancient lost wax handed down from precision casting, through to the materials and Process Improvement, modern methods of precision casting based on the ancient craft was an important development. Therefore, the development of the aviation industry to promote the application of precision casting, precision casting and continuous improvement and perfection, but also further improve the performance of the aviation industry has created favorable conditions.

China is in the last century, the fifties and sixties began casting for industrial production. Later this advanced steel casting process has been tremendous development, one after another in the aerospace, automotive, machine tools, ships, internal combustion engines, gas turbine, telecommunications equipment, weapons, medical equipment and cutting tools and other manufacturing industries that are widely used, but also for arts and crafts manufacturing.

The so-called precision casting process, it simply is to use fusible materials (such as wax or plastic) made of fusible models (Rong mold or model), on which the fire-resistant coating Ruogan layer of special coating, drying and hardening after the formation of After a whole shell, and then steam or hot water from the melting of the shell model, and then placed in sand box shell, filled with dry sand in the molding around it, and finally cast into the roaster in the high temperature calcination (such as high strength shell, it can not form the shell after the stripping direct baking), the mold or shell after roasting, after which pouring molten metal and are casting.
