美国的熔模铸造工业,专业厂占63％,只为本厂提供产品的工厂占16％,既为本厂服务又对外协作的工厂占21％。各工厂从事熔模铸造的人员从2人到273人,1982年各工厂的产值从20英磅到500万英磅。1983年与1982年相比,约25％的厂家生产稍稍降低,35％的厂家生产略有提高。今后,将使用熔模与热等静压粉末冶金复合或不同金属 The investment casting industry in the United States accounts for 63% of the specialized factories and 16% of the factories that only provide the products for the factory. The 21% of factories that serve both the factory and the outside cooperate. From two to 273 people engaged in investment casting at each plant, in 1982 the output value of each plant ranged from 20 to 5 million pounds. In 1983, compared with 1982, about 25% of the manufacturers produced a slight decrease, while 35% of the manufacturers made slight increases. In the future, fusible and hot-isostatic powder metallurgy composites or different metals will be used
