前 言 铝合金石膏型熔模精密铸造技术是近年来国外兴起的一项新颖的铸造工艺,它可以铸造出其它方法难以成形的薄壁、复杂、异形、整体、无余量铝合金优质精铸件。无论在国防工业还是在民用工业部门均有广泛的应用前景和很高的技术经济效益,特别适用于新产品研制、老产品改进改型、小批量多品种精铸件的生产。该项技术国内原属空白。
Introduction Aluminum alloy gypsum type investment precision casting technology is a novel casting technology emerging abroad in recent years. It can cast thin-walled, complicated, shaped, integral and non-surplus aluminum alloy high quality casting parts that are difficult to be formed by other methods. No matter in the national defense industry or in the civil industry, it has a wide range of application prospects and high technical and economic benefits. It is especially suitable for the production of new products, improvement of old products and production of small-sized and multi-species precision castings. The technology was originally blank in the country.
