        摘要：Examinations and statistics about casting dimensions have been accomplised in three ranks of typical investment casting factories.Referring to the ISO 8062-84 and the GB6414-86,it shows that the dimensional tolerances of castings made by rank-A and rank-B factories have conformed to grade CTS～CT7 of GB6414-86,and those made by rank-C factories,conformed to grade CT8.
