After China has entered the reform and opening -up of the modern socialist country, the level of economic development, scientific and technological progress and the level of industrialization have shown a certain trend of development, this has effectively promoted the process of China’s machinery reform and industrialization innovation, especially the performance optimization of large-scale mechanical parts for China’s machinery industrialization process is also very important. Focusing on improving the performance of the mechanical bearing seat, this paper mainly analyzes the influence of different casting technology levels on improving and changing the performance of the mechanical equipment in China.
