铝合金石膏型熔模精铸是一项先进铸造工艺,它把熔模铸造和石膏型铸造有机地结合起来,在铸造高精度、薄壁、复杂整体铝合金铸件方面具有独到之处,是铝合金铸造技术上很有发展前途的一项工艺。一一四厂、西工大、四院、四三○厂、五三○八厂等九个单位组成研制攻关组,系统地研究了石膏铸型材料、模料、A356铝合金、以及整个石膏型熔模精铸工艺:成功地试制了
Aluminum alloy gypsum investment casting is an advanced casting technology, which combines investment casting and gypsum casting organically, in the casting of high-precision, thin-walled, complex overall aluminum alloy casting has the uniqueness of aluminum Alloy casting technology is very promising for a process. One by one, four factories, the Western Engineering University, four homes, 430 plants, 5380 plants and other nine units to develop research groups, systematically studied the gypsum mold materials, mold materials, A356 aluminum alloy, and the gypsum type melting Die casting process: a successful trial of the system
