Wax Pattern Precision Casting and Lost-Wax Method

Lost-Wax Method: The "lost-wax method" is also known as "investment casting" or the "investment precision casting process." It uses a one-time meltable wax material as the pattern, then repeatedly coats the wax pattern with multiple layers of specially formulated refractory coating to form a shell. After the shell hardens, the wax pattern is melted out in steam and hot water to obtain the shell mold. The shell mold is then placed in a calcination furnace for high-temperature calcination, and finally the prepared alloy is poured while hot. After the metal solidifies, the shell is broken to obtain the casting. This process can produce very complex shapes. Lost-Wax Process Flow: Brass zodiac figures made by the lost-wax method
