On June 6, at the 2024 SMM Die Casting Industry Summit Forum - Roundtable Forum hosted by SMM in Ningbo, Zhejiang, Zhang Yuebo, General Manager of New Material Technology of Shuaiyichi New Material Group Co., Ltd., said that currently there are more than 100 patents for global heat-free treatment materials, but in fact, there are only more than 10 patents for aluminum heat-free treatment, and no more than 5 have been applied. Ignoring the patent itself, taking vanadium as an example, applying for a patent alone will increase the cost by more than 1,000 yuan per ton. Heat-free treatment materials were first developed abroad, and the development in China is relatively slow.
