Vacuum precision casting is a casting process in which metals are smelted, poured and crystallized in a vacuum chamber. It can reduce the gas content in the metal and prevent metal oxidation and trachoma. Demanding castings can be produced in this way. vacuum casting services The cost of vacuum casting is high, and it is generally used for high-quality castings, and the casting mold should not contain volatiles.
