What is the investment casting process?
The investment casting process refers to a metal casting process where a disposable wax model identical to the casting is produced from an injection molding type of tool. The wax model is then repeatedly dipped into liquid ceramic slurry to form a layered mold. After the ceramic has dried, the disposable wax is burned out leaving a hollow cavity into which the metal is poured. This process is sometimes called the lost wax process.
