Future challenges and development directions of precision casting
Although China's precision casting output leads the world, it still faces multiple challenges: Technology gap: high-end castings such as aircraft engine blades and nuclear power components rely on imports, and key processes (such as riserless casting) have not yet been broken through; energy consumption is 2-3 times that of developed countries, and large processing allowances lead to material waste. Environmental pressure: Traditional casting produces a large amount of waste sand and waste gas, and the domestic recycling rate is less than 50%, while Germany has achieved 100% recycling. Talent shortage: The casting major in colleges and universities has been cancelled, the industry's attractiveness has declined, and the gap in high-skilled talents restricts innovation. Future development directions include: Intelligent upgrade: Introduce digital twin technology to optimize process parameters, such as the 3D printing sand mold technology developed by Shenzhu, which shorten...
