SHELL COREMAKING: TOP PROCESS 粘土湿砂、自硬砂工艺比例最大
Total Number of U.S. Plants 铸造企业数量
The shell coremaking process remains the most popular method, edging out air-set/nobake by 2%. 制造壳芯工艺仍是使用最多的工艺，比自硬砂工艺使用率高2%。
Coremaking Methods
Leader: Shell Last Place: Cast-in Inserts A little more than half of the participating facilities (893)
reported using some method of coremaking. Shell and air- set/nobake coremaking were the top two responses, with 609 and 571 facilities reportedly using the methods, respectively.

制芯工艺
第一位：壳型 最后一位：镶铸件
报告显示，超过一半的铸造企业（893家）采用了制 芯工艺。壳芯和自硬砂制芯工艺是使用最多的2种，分 别为609家企业和571家企业。使用最少的是陶瓷芯工 艺（99家企业）和镶铸件（40家企业）。 约80%的调查企业采用一种以上制芯工艺，182家 企业仅采用一种制芯工艺。壳型和自硬砂两种工艺结合 是使用最多的工艺，有416家企业采用，调查企业中有 340家采用壳型和粘土湿型砂工艺。
47.3%
Aluminum is the dominant material, with 800 facilities (47.3% of respondents) pouring some type of aluminum alloy.
铝是主要材料，用800设施（受访者47.3％） 浇某种类型的铝合金。
