Some investors asked questions on the investor interaction platform: good leadership. I think the company recently replied to other investors that "the company has obtained the single crystal blade order of overseas customers\' aeroengines". I have learned aviation related professional knowledge. As far as I know, the production of hot end turbine blades of overseas commercial aeroengines, especially stage 1 and 2 high vortex single crystal blades, is very difficult, so I have never found a Chinese supplier to produce them in history. I would like to ask the leaders, is Yingliu the first company in Chinese history to get overseas commercial engine single crystal blades, and are there other manufacturers in China to get such orders
Anhui Yingliu Electromechanical Co.Ltd(603308) (603308. SH) said on the investor interaction platform on January 7 that, as you said, it is very difficult to produce overseas Aeroengine Blades. Generally, customers will choose European and American suppliers such as PCC, and the process of obtaining the above orders is very difficult. First, Yingliu developed directional crystal and single crystal blades for overseas gas turbines and supplied them continuously, gradually gaining the trust of customers, then developed aeroengine casings and supplied them continuously, and finally obtained orders for overseas Aeroengine Blades. The whole process took 5-6 years. At present, the above-mentioned overseas aeroengine single crystal blades have achieved technological breakthroughs. At the same time, the operation of the raised investment project has improved the company's engineering industrialization ability and further enhanced its product competitiveness. At present, Yingliu is one of the few enterprises that have received orders for hot end blades of overseas commercial engines.
