目前不锈钢精密铸造技术已投入工业生产，当时航空喷气发动机的发展需要制造叶轮、刀片、喷嘴等复杂的形状、精确的产品尺寸以及表面光泽耐热合金零件。
At present, stainless steel precision casting technology has been put into industrial production. At that time, the development of Aerojet engine needed to manufacture impeller, blade, nozzle and other complex shapes, accurate product dimensions and surface gloss heat-resistant alloy parts.
耐热合金材料难以加工，零件的额头形状复杂，无法用其他方法制作，必须找到新的精密成型工艺，因此很多制造商从古代的蜂蜡铸造中吸取了教训。
Heat resistant alloy materials are difficult to process, and the forehead shape of parts is complex, which can not be made by other methods. We must find a new precision forming process. Therefore, many manufacturers have learned a lesson from the ancient beeswax casting.
不锈钢精密铸造在制造过程中主要改进材料和工艺技术，现代铸造方法以古代工艺为基础，能够取得相对重要的发展，因此航空工业的发展也在有效地推动这些技术的应用。
Stainless steel precision casting mainly improves materials and technology in the manufacturing process. Modern casting methods are based on ancient technology and can achieve relatively important development. Therefore, the development of aviation industry is also effectively promoting the application of these technologie
