Lost Wax Investment Casting
Lost wax investment casting is an ancient yet highly precise manufacturing process. It begins with creating a wax model of the desired part. This wax model is then coated with a refractory ceramic material layer by layer to form a shell. The wax is melted or burned out, leaving a cavity inside the ceramic shell. Molten metal is then poured into the cavity, and after solidification, the ceramic shell is removed, revealing the final casting.
