METHOD FOR PRODUCING METAL CASTINGS |
摘要 |
Metal castings having reduced residual carbon ash and surface flaws are produced by an evaporative pattern casting process, in which an organic foam pattern is vaporized upon contact with a molten metal leaving a metal replica of the pattern. The organic foam used in this process comprises a polymer formed by polymerizing CO2 with one or more oxirane compounds. |
