Advantage of Precision Casting Method
Modern Investment precision 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.
