Precision casting wax, also known as investment casting wax or lost wax casting wax, is a specialized type of wax used in the precision casting process. It is primarily used to create intricate and detailed patterns or molds, which are later used to produce metal castings with high precision and accuracy.
The wax tree is then coated with a ceramic shell, which is created by repeatedly dipping the tree into a ceramic slurry and then coating it with a fine ceramic powder. This process is repeated several times to build up a thick and strong shell around the wax patterns.
Once the ceramic shell has dried and hardened, it is placed in a high-temperature furnace or kiln. The wax inside the shell melts and is burned out, leaving behind a cavity in the shape of the original wax pattern. This is why the process is often referred to as "lost wax casting."
