20 0 1— 2 0 0 2年美国和德国相继召开了 3个有关消失模铸造研讨会 ,共交流 45篇报告。报告归纳出北美和欧洲在消失模铸造研究上有 3大热点 :开展消除铝合金消失模铸造缺陷的研究 ;完善发泡模具及白区制模技术 ;探索消失模铸造模拟和快速原型制造技术。介绍了国外消失模铸造企业现状 ,指出我国消失模铸造与世界先进消失模技术的 3大差距
20 0 1-2 0 0 2 years the United States and Germany have held three seminars on lost foam casting, a total of 45 reports exchanged. The report summarizes the North America and Europe in the Lost Foam Casting Research has three major hot spots: to carry out the elimination of aluminum alloy lost foam casting defects; improve the foam mold and white area molding technology; to explore the Lost Foam casting simulation and rapid prototyping technology. The status of lost foam casting enterprises in foreign countries is introduced, and the three major gaps between lost foam casting in China and the advanced lost foam technology in the world
