铝合金石膏型熔模精密铸造是一门新颖的铸造工艺技术,在铸造薄壁、复杂、整体优质铝合金铸件工艺方面有独到之处,具有较高的技术经济价值。这种铸造工艺技术目前国内还是空白。本文,根据美国泰克铸造公司总裁GOTT—HOLD先生的技术讲座撰写,对铝合金石膏型熔模精密铸造工艺作一些介绍,以供铸造工作者参考。铝合金石膏型熔模精密铸造采用熔模石膏型铸造薄壁、复杂、优质的整体铝合金精铸件的一种新颖的铸造方法。它的主要工序有模具(工装)的设计与制造、蜡模的制造与装配、石膏型的制造、石膏型的脱蜡与焙烧、合金的
Aluminum alloy gypsum-type investment casting is a novel casting technology, casting thin-walled, complex, overall high-quality aluminum alloy casting process has its own uniqueness, with high technical and economic value. This casting technology is still blank at home. This article, based on a technical lecture by Mr. GOTT-HOLD, President of Tektronix Foundry, presents some introductory texts on the casting process of aluminum alloy gypsum castings for the reference of foundry workers. Aluminum alloy gypsum-type investment casting Precision casting using cast-gypsum casting thin-walled, complex, high quality overall cast aluminum alloy casting a novel method. Its main processes include design and manufacture of molds (tooling), manufacture and assembly of wax molds, manufacture of gypsum-type, dewaxing and roasting of gypsum-type, alloyed
