The ceramic shell mold method until the wax type is the same as the solid mold method, but after a slurry and sand (or floating sand), not the mold operation, but repeatedly to the slurry and sand until the predetermined shell thickness is obtained. Dry, heating, melting out of wax, high temperature heating and then pouring, this method is widely used in the current dewaxing precision casting industry, because it has the following advantages:
(1) Dimensions (hakɛ) ɲuman sabatili .
(2) Baara kɛli ni fɛnw ye minnu tɛ se ka fɛn kɛ .
(3) A girinya ka nɔgɔn, a ta ka nɔgɔn, a minɛcogo ka nɔgɔn, ani a dilanni ka nɔgɔn .
